TLDR – NOT HARMLESS
Evaluation of human papilloma virus in semen as a risk factor for low sperm quality and poor in vitro fertilization outcomes: a systematic review and meta-analysis
A review of the literature regarding ART outcomes showed an association between HPV infection and decreased PR, and an even stronger association between HPV infection and increased MR.
-increased miscarriage rate, lower odds of conceiving
Conclusion: Our meta-analysis shows a negative effect of HPV on sperm concentration, motility, and morphology. Further subgroup and categorical analysis confirmed the clinical significance of impaired sperm motility in HPV-infected sperm, although the sperm count and morphology must be carefully analyzed. The studies reviewed reported lower PR and increased MR in couples with HPV-infected sperm. As most studies had a moderate risk of bias, these observations warrant further large, well-designed studies before introducing clinical management recommendations.
Yes, this is a dealbreaker to sane women.
Human papilloma virus: to what degree does this sexually transmitted infection affect male fertility?

Human papillomavirus infection and fertility alteration: a systematic review
Results: HPV infections are shown to be significantly associated to many adverse effects in the reproductive function. These adverse effects were reported in different levels from cells production to pregnancy and may be related to the infecting genotype.
Conclusions: It appears from this study that HPV detection and genotyping could be of great value in infertility diagnosis at least in idiopathic infertility cases. Like for the risk of carcinogenesis, another classification of HPV regarding the risk of fertility alteration may be considered after deep investigations.
Human Papilloma Virus (HPV) and Fertilization: A Mini Review
Sorry but if something makes you less virile, you’re less of a man.
Human papilloma virus (HPV) is one of the most prevalent viral sexually transmitted diseases. The ability of HPV to induce malignancy in the anogenital tract and stomato-pharyngeal cavity is well documented. Moreover, HPV infection may also affect reproductive health and fertility. Although, the impact of HPV on female fertility has not been thoroughly studied it has been found also to have an impact on semen parameters. Relative information can be obtained from studies investigating the relationship between HPV and pregnancy success. Furthermore, there is an ongoing debate whether HPV alters the efficacy of assisted reproductive technologies. An association between HPV and assisted reproductive technologies (ART) programs has been reported. Nevertheless, due to conflicting data and the small number of existing studies further research is required. It remains to be clarified whether HPV detection and genotyping could be included in the diagnostic procedures in couples undergoing in vitro fertilization (IVF)/intrauterine insemination (IUI) treatments. Vaccination of both genders against HPV can reduce the prevalence of HPV infection and eliminate its implications on human fertility. The aim of the present mini-review is to reiterate the association between HPV and human fertility through a systematic literature review.
The role of human papillomavirus on sperm function
I love how many yanks pull a Henry 8th and blame women for their own infertility, in this century.
Recent findings: HPVs are agents of the most common sexually transmitted disease and can lead to warts and cancers both in men and women. A high incidence of HPV infection has been demonstrated in sperm from sexually active men with and without risk factors for HPV and from infertile patients.
Semen infection is associated to an impairment of sperm parameters suggesting a possible role in male infertility. – really???
Interestingly, it has been demonstrated that when HPV is present in semen only a percentage of total cells are infected
-only? a? 100% is a percentage too…
and the virus can be localized in sperm or in exfoliated cells with different impact on sperm motility. Moreover, infected sperm are able to penetrate the oocyte, to deliver HPV genome in the oocyte and HPV genes can be actively transcribed by the fertilized oocyte.
-wouldn’t it be ironic if it made the kids or grandkids infertile instead? because they were conceived with it, a polluted germline
Recently an increased risk of pregnancy loss has been demonstrated in couples undergoing in-vitro fertilization and particularly when HPV DNA was present in semen samples of male partners.– no blaming women this time, unless women haz sperm?
Summary: To date, no effective treatment, control strategy and prevention is provided for men despite the reported high incidence of HPV semen infection.
– no hurt their feefees? NAW
Because this infection in men is also a problem for partners, and because growing evidence suggests that semen infection may cause infertility and early miscarriage, more attention should be paid to male HPV infection. This study reviews the more recent literature about the role of HPV infection on sperm function and human reproduction.– Manosphere fears this topic and all male degenerate accountability.

High-risk human papillomavirus in semen is associated with poor sperm progressive motility and a high sperm DNA fragmentation index in infertile men
Does the presence of human papillomavirus (HPV) in semen impact seminal parameters and sperm DNA quality in white European men seeking medical help for primary couple’s infertility?
>in the germline of
Never talk about it, I’m sure it’ll be fine.
HPV seminal infections involving high-risk (HR) genotypes are associated with impaired sperm progressive motility and sperm DNA fragmentation (SDF) values.
HPV is commonly present in semen samples.
No? F no it’s not. Stop sparing slutty blushes.
The overall rate of HPV positivity was 15.5%
so 1 in 7, uncommon at best. No normalizing pathology please.
And it varies majorly by race and sexuality. Not sex because it’s sexual, obviously.
Sperm progressive motility was significantly lower (P = 0.01) while SDF values were higher (P = 0.005) in HPV+ men compared to those with no HPV. In particular, HR HPV+ men had lower sperm progressive motility (P = 0.007) and higher SDF values (P = 0.003) than those with a negative HPV test. Univariable analysis showed that HR HPV+ was associated with impaired sperm progressive motility (P = 0.002) and SDF values (P = 0.003). In the multivariable analysis, age, FSH levels and testicular volume were significantly associated with impaired sperm progressive motility (all P ≤ 0.04). Conversely BMI, CCI, smoking habits and HPV status were not. Only age (P = 0.02) and FSH (P = 0.01) were significantly associated with SDF, after accounting for BMI, CCI, testicular volume, smoking habits and HPV status.
It’s worse for the older men.
Impact of human papillomavirus infection in semen on sperm progressive motility in infertile men: a systematic review and meta-analysis
Background: Human papillomavirus (HPV) has been considered as one of the most common sexually transmitted viruses that may be linked to unexplained infertility in men. The possible mechanisms underlying correlation between HPV infection and infertility could be related to the altered sperm parameters. Current studies have investigated the effect of HPV seminal infection on sperm quality in infertile men, but have shown inconsistent results.
Methods: We systematically searched PubMed, Embase, Web of Science and CNKI for studies that examined the association between HPV seminal infection and sperm progressive motility. Data were pooled using a random-effects model. Outcomes were the sperm progressive motility rate. Results are expressed as standardised mean difference (SMD) with 95% confidence interval (CI). Heterogeneity was evaluated by the I-square (I2) statistic.
Results: Ten studies were identified, including 616 infertile patients with HPV seminal infection and 2029 infertile controls without HPV seminal infection. Our meta-analysis results indicated that sperm progressive motility was significantly reduced in HPV-infected semen samples compared with non-infected groups [SMD:-0.88, 95% CI:-1.17 ~ – 0.59]. There existed statistical heterogeneity (I2 value: 86%) and the subgroup analysis suggested that study region might be the causes of heterogeneity.
Conclusions: HPV semen infection could significantly reduce sperm progressive motility in infertile individuals. There were some limitations in the study such as the differences in age, sample sizes and the number of HPV genotypes detected. Further evidences are needed to better elucidate the relationship between HPV seminal infection and sperm quality.

The present study illustrates that there was a significant negative effect of ASA on sperm concentration, sperm motility (a+b) and sperm liquefaction.
The prevalence of Human Papilloma Virus (HPV) infection in the oligospermic and azoospermic men
The current study shows that HPV infection can affect on sperm count and motility and decrease count of sperm cell and decrease motility capability of these cells.
Among 50 confirmed oligospermic male, 15 were HPV DNA positive (30%).
In azoospemic group we had 8 HPV DNA positive (40%) and in normal group just 3 of 20(15%) samples were positive.
-what r the odds?
we found statistical significant relationship for sperm count (p<0.05) and sperm motility (slow) (p<0.05) in oligospermic group positive samples compared with negative. In the present study, 13 HPV genotypes were detected among positive samples. HPV genotypes 16, 45 in the high risk group and 6,11,42 in the low risk group were more frequent than the others.

no muh scientism and IVF cope
This study demonstrated that conventional sperm selection rarely eliminates HPV sperm infection. More attention should be paid to the reproductive health of infected patients because, not only can HPV be transmitted, but it may also have a negative effect on development of the fetus.

Is HPV the Novel Target in Male Idiopathic Infertility? A Systematic Review of the Literature
Infertility is an important health problem that affects up to 16% of couples worldwide.
1 in 7, where have I heard THAT before….? [scroll up]
Male infertility is responsible for about 50% of the cases,
–NAY, men are never responsible for their own in/fertility, have you been online recently?
and the various causes of male infertility may be classified in pre-testicular (for example hypothalamic diseases), testicular, and post-testicular (for example obstructive pathologies of seminal ducts) causes. Sexually transmitted infections (STI) are increasingly widely accepted by researchers and clinicians as etiological factors of male infertility. In particular, several recent reports have documented the presence of HPV in seminal fluid and observed that sperm infection can also be present in sexually active asymptomatic male and infertile patients.
In this review, we aimed to perform a systematic review of the whole body of literature exploring the impact of HPV infection in natural and assisted fertility outcomes, from both an experimental and a clinical point of view. Starting from in-vitro studies in animals up to in-vivo studies in humans, we aimed to study and evaluate the weight of this infection as a possible cause of idiopathic infertility in males with any known cause of conception failure.
Significant Correlation between High-Risk HPV DNA in Semen and Impairment of Sperm Quality in Infertile Men
guess the result
A total of 140 subjects participated in the current study. Among 70 confirmed infertile males, only 8 (11.43%) cases tested positive for high-risk HPV and all fertile men were HPV-negative. This data revealed a significant association between high-risk HPV and male infertility (P=0.03). The percentage of normal sperm morphology and sperm motility rate significantly declined in men infected with HPV (P<0.001).
and all fertile men were HPV-negative
oof and the sluts of both sexes are dying out, I am distraught.
The genetics of the future are fairing brighter than you’d think.
Conclusion: There was a significantly higher prevalence of high-risk HPV in infertile men than fertile men. HPV infection seemed to be a risk factor for male infertility. Additional, larger studies should be conducted to confirm the impact of HPV on male infertility.

Association between human papillomavirus infection and sperm quality: A systematic review and a meta-analysis
Human papillomavirus (HPV) has a high incidence rate in both males and females.
-maybe where you live
HPV infection in women has been shown to affect fertility and lead to foetal death and pregnancy loss. However, research on HPV infection in men is limited.

-Ashley Madison wasn’t full of women stepping out, was it?
The aim of this study was to study the effect of HPV infection in semen on sperm quality and present the findings of previous studies through a meta-analysis. Databases including PubMed, MEDLINE, EMBASE, Web of Science, Cochrane Library, WanFang data and China National Knowledge Infrastructure were searched for relevant studies. A systematic review and meta-analysis were performed, and 17 studies were included for analyses based on a set criterion. Meta-analyses indicated that HPV infection in semen significantly reduced sperm concentration (SMD = -0.12, 95% CI: -0.21 to -0.03, p = .009), sperm motility (SMD = -0.55, 95% CI: -0.780 to -0.33, p = .000), sperm viability (SMD = -0.55, 95% CI: -0.780 to -0.33, p = .000) and sperm morphology (SMD = -0.34, 95% CI: -0.61 to -0.07, p = .015). The high-risk HPV (HrHPV) infection could significantly reduce sperm count (SMD = -0.65, 95% CI: -1.11 to -0.18, p = .007) compared with high-risk HPV (LrHPV) infection.
In conclusion, HPV infection in semen significantly reduced sperm quality, and the HrHPV infection could significantly reduce sperm count compared with LrHPV.

Semen parameters and sperm morphology in men in unexplained recurrent spontaneous abortion, before and during a 3 year follow-up period
Baby death aborts the defective DNA, HPV fucks with your sperm’s DNA. Water is wet.
HPV makes you biologically unfit. According to the ultimate test, the womb.
To investigate the role of the ‘male factor’ in the pathogenesis of recurrent spontaneous abortion (RSA), especially sperm morphology abnormalities, 120 previously selected couples with unexplained RSA were studied for sperm parameters retrospectively and prospectively. The patients were subdivided into three subgroups, depending on their reproductive outcome during the 3 years of follow-up study: (i) 48 RSA couples who achieved a successful pregnancy; (ii) 39 RSA couples who experienced further abortions, and (iii) 33 RSA couples who experienced infertility during the follow-up period. A semen analysis was performed twice at the time of inclusion in this study, and twice again during the 3 year follow-up period. No significant differences in semen parameters were observed between RSA males and fertile controls. Instead, significant differences were observed between the group of RSA couples who experienced infertility during the follow-up and the other two groups (RSA couples who achieved successful pregnancy and RSA couples who experienced miscarriages and no live birth during the follow-up) for sperm concentration (P < 0.01 and P < 0.01 respectively), sperm motility (P < 0.01 and P < 0.01 respectively) and sperm morphology abnormalities (P < 0.01 and P < 0.01 respectively).
Sperm DNA fragmentation in couples with unexplained recurrent spontaneous abortions
The aim of the present study was to evaluate the degree of sperm DNA fragmentation in couples with idiopathic recurrent spontaneous abortion (RSA) and in those with no history of infertility or abortion. In this cohort study, 30 couples with RSA and 30 fertile couples as control group completed the demographic data questionnaires, and their semen samples were analysed according to World Health Organization (WHO) standards (September 2009-March 2010) for evaluation of sperm DNA fragmentation, using sperm chromatin dispersion (SCD) technique. The percentage of morphologically normal sperm was significantly lower in RSA patients compared with control group (51.50 ± 11.60 versus 58.00 ± 9.05, P = 0.019), but not in other parameters. Additionally, the level of abnormal DNA fragmentation in the RSA group was significantly higher than in the control group (43.3% versus 16.7%, P = 0.024). Our results indicated a negative correlation between the number of sperm with progressive motility and DNA fragmentation (r = -0.613; P < 0.001). The sperm from men with a history of RSA had a higher incidence of DNA fragmentation and poor motility than those of the control group, indicating a possible relationship between idiopathic RSA and DNA fragmentation.– idiopathic? Are you shitting me?
sure it is
Correlation of recurrent pregnancy loss with sperm parameters and sperm DNA fragmentation
This study has indicated that sperm from men with a history of RPL have a higher incidence of DNA damage and poor motility compared with fertile males.
Water is wet. Miscarriage is meant to happen to dodgy DNA.
Sperm chromatin integrity may predict future fertility for unexplained recurrent spontaneous abortion patients
“unexplained” – just assume the echo for comedic effect by now
The RSA group was further separated into three subgroups, depending on their reproductive outcome during the 12 months after they were enrolled in the study: the pregnancy subgroup consisted of 43 men whose partners achieved a successful pregnancy up to at least the 24th week of gestation; the abortion subgroup included 31 men whose partners experienced further abortions; and the infertile subgroup had 37 men whose partners did not have any positive pregnancy test after regular, unprotected intercourse. Significantly lower proportion of sperm with normal morphology was found in the abortion subgroup (14.7 ± 4.3%) than in the control group (17.5 ± 5.0%). Sperm concentrations were significantly lower in the infertile subgroup (55.7 ± 24.1%) than in the controls (68.6 ± 27.8%). The rates of abnormal sperm chromatin integrity were significantly higher in the abortion (16.7 ± 7.7%) and infertile (16.3 ± 6.6%) subgroups, compared to the control group (13.0 ± 4.4%). Logistic regression analysis showed that the subsequent reproductive outcome of the 111 RSA patients was negatively correlated to the rates of abnormal sperm chromatin integrity. In conclusion, sperm chromatin integrity, sperm morphology, and sperm concentration were associated with future reproductive outcome of RSA patients. The sperm chromatin integrity was a significant predictor for future abortion and infertility.
But men are never responsible for miscarriage, perish the THOUGHT.
I mean – where are the STUDIES?!
Cytochemical evaluation of sperm chromatin and DNA integrity in couples with unexplained recurrent spontaneous abortions
unexplained….. sigh, ok.
Our study showed that in the cases of RSA, slow motility had a significant reduction in comparison with controls and also spermatozoa of men from RSA group had less chromatin condensation and poorer DNA integrity than spermatozoa that obtained from fertile men with no history of RSA.

Human sperm deoxyribonucleic acid fragmentation by specific types of papillomavirus
Conclusion: Human papillomavirus type 16 and 31 deoxyribonucleic acid caused deoxyribonucleic acid breakages characteristic of apoptotic but not necrotic sperm.
The data suggest that these human papillomavirus types may adversely affect subsequent embryonic development after fertilization. Sperm deoxyribonucleic acid appears to resist human papillomavirus types 18, 33, and 6/11 or repairing mechanisms occurred. Although enhanced motility was found in human papillomavirus–exposed sperm, important velocity parameters were decreased, suggesting impaired sperm function.-swimming in circles isn’t motility, really

Negative Impact of Elevated DNA Fragmentation and Human Papillomavirus (HPV) Presence in Sperm on the Outcome of Intra-Uterine Insemination (IUI)
i.e. no, you won’t just get IVF
We wanted to determine the sperm DNA fragmentation index (DFI) cutoff for clinical pregnancies in women receiving intra-uterine insemination (IUI) with this sperm and to assess the contribution of Human Papillomavirus (HPV) infection on sperm DNA damage and its impact on clinical pregnancies. Prospective non-interventional multi-center study with 161 infertile couples going through 209 cycles of IUI in hospital fertility centers in Flanders, Belgium. Measurement of DFI and HPV DNA with type specific quantitative PCRs (HPV 6, 11, 16, 18, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66 and 68) in sperm before its use in IUI. Clinical pregnancy (CP) rate was used as the outcome to analyze the impact on fertility outcome and to calculated the clinical cutoff value for DFI. A DFI criterion value of 26% was obtained by receiver operating characteristic (ROC) curve analysis. Couples with a male DFI > 26% had significantly less CPs than couples with DFI below 26% (OR 0.0326; 95% CI 0.0019 to 0.5400; p = 0.017). In sperm, HPV prevalence was 14.8%/IUI cycle. Sperm samples containing HPV had a significantly higher DFI compared to HPV negative sperm samples (29.8% vs. 20.9%; p = 0.011). When HPV-virions were present in sperm, no clinical pregnancies were observed. More than 1 in 5 of samples with normal semen parameters (17/78; 21.8%) had an elevated DFI or was HPV positive. Sperm DFI is a robust predictor of clinical pregnancies in women receiving IUI with this sperm. When DFI exceeds 26%, clinical pregnancies are less likely and in vitro fertilization techniques should be considered
When HPV-virions were present in sperm, no clinical pregnancies were observed.
Sperm viral infection and male infertility: focus on HBV, HCV, HIV, HPV, HSV, HCMV, and AAV
Chronic viral infections can infect sperm and are considered a risk factor in male infertility. Recent studies have shown that the presence of HIV, HBV or HCV in semen impairs sperm parameters, DNA integrity, and in particular reduces forward motility. In contrast, very little is known about semen infection with human papillomaviruses (HPV), herpesviruses (HSV), cytomegalovirus (HCMV), and adeno-associated virus (AAV). At present, EU directives for the viral screening of couples undergoing assisted reproduction techniques require only the evaluation of HIV, HBV, and HCV.
-all trust the EU guys
However, growing evidence suggests that HPV, HSV, and HCMV might play a major role in male infertility and it has been demonstrated that HPV semen infection has a negative influence on sperm parameters, fertilization, and the abortion rate.
-somebody else look up herpes, I’m lazy
Besides the risk of horizontal or vertical transmission, the negative impact of any viral sperm infection on male reproductive function seems to be dramatic.
-Really, f-ing fascinating!
In addition, treatment with antiviral and antiretroviral therapies may further affect sperm parameters. In this review we attempted to focus on the interactions between defined sperm viral infections and their association with male fertility disorders. All viruses considered in this article have a potentially negative effect on male reproductive function and dangerous infections can be transmitted to partners and newborns. In light of this evidence, we suggest performing targeted sperm washing procedures for each sperm infection and to strongly consider screening male patients seeking fertility for HPV, HSV, and HCMV, both to avoid viral transmission and to improve assisted or even spontaneous fertility outcome

HPV infection in semen: results from a new molecular approach
Let’s get molecular.
Human papillomavirus (HPV) is the agent of the most common sexually transmitted diseases causing a variety of clinical manifestations ranging from warts to cancer. Oncogenic HPV infection is the major cause of cervical cancer and less frequently of penile cancers. Its presence in semen is widely known, but the effects on fertility are still controversial. – how? allergic to facts?
We developed a new approach to evaluate virus localisation in the different semen components. We analysed also the specific genotype localisation and viral DNA quantity by qPCR. Results show that HPV DNA can be identified in every fraction of semen: spermatozoa, somatic cells and seminal plasma. Different samples can contain the HPV DNA in different fractions and several HPV genotypes can be found in the same fraction. Additionally, different fractions may contain multiple HPV genotypes in different relative quantity. We analysed the wholeness of HPV DNA in sperm cells by qPCR. In one sample more than half of viral genomes were defective, suggesting a possible recombination event. The new method allows to easily distinguish different sperm infections and to observe the possible effects on semen. The data support the proposed role of HPV in decreased fertility and prompt new possible consequences of the infection in semen.
