Sønnichsen-Dreehsen AS, Fedder J, Wod M, Thorarinsson CT, Nørgård BM. The association between paternal diabetes mellitus and successful pregnancy-Examined in a nationwide population undergoing reproductive treatment. Andrology 2024. [PMID: 39078246 DOI: 10.1111/andr.13702] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2024] [Revised: 07/02/2024] [Accepted: 07/05/2024] [Indexed: 07/31/2024]
Abstract
BACKGROUND About 15% of all pregnancies end in pregnancy loss. As most studies have focused on maternal factors little is known regarding the influence of paternal factors on the chance of successful pregnancy. OBJECTIVES This cohort study aims to assess the chance of biochemical pregnancy, clinical pregnancy, and live-born children in couples where the male partner has diabetes mellitus (DM). MATERIALS AND METHODS We performed a nationwide cohort study. Couples undergoing assisted reproductive technology treatment from 2006 to 2019 were included. The exposed cohorts comprised embryo transfers in couples with paternal type 1 DM (T1DM), type 2 DM (T2DM), or mixed type DM (TMDM). The unexposed cohort included embryo transfers in couples without paternal DM. RESULTS A total of 101,875 embryo transfers were included. Of these, 503 males had T1DM, 225 males had T2DM, 263 males had TMDM, and 100,884 did not have DM. For paternal T1DM, the adjusted OR for achieving a biochemical pregnancy, clinical pregnancy, and live-born child were 0.97 (95% CI 0.77-1.23), 1.08 (95% CI 0.65-1.79), and 0.75 (95% CI 0.49-1.14), respectively. For paternal T2DM, the adjusted OR for achieving a biochemical pregnancy, clinical pregnancy, and live-born child were 0.80 (95% CI 0.56;1.16), 0.67 (95% CI 0.32-1.41), and 1.03 (95% CI 0.48-2.20), respectively. For the paternal TMDM, the adjusted OR for achieving a biochemical pregnancy, clinical pregnancy and livebirth were 0.95 (95% CI 0.67-1.33), 1.31 (95% CI 0.56-2.92), and 1.19 (95% CI 0.59-2.38), respectively. CONCLUSION Paternal DM was not associated with a statistically significant decreased chance of biochemical pregnancy, clinical pregnancy, or live birth.

Friedman S, Thorarinsson CT, Wod M, Fedder J, Nørgård BM. Paternal Inflammatory Bowel Disease and the Risk of Pregnancy Loss. Inflamm Bowel Dis 2024:izae132. [PMID: 38944809 DOI: 10.1093/ibd/izae132] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/11/2024] [Indexed: 07/01/2024]
Abstract
BACKGROUND Only about 30% of conceptions end in live births, yet there are little data on paternal causes of pregnancy loss. Men with inflammatory bowel disease may have multiple disease-related issues that may affect fertility. We aimed to examine pregnancy outcomes in women undergoing assisted reproduction whose male partners had Crohn's disease or ulcerative colitis. METHODS This nationwide study included all embryo transfers registered in the Danish Assisted Reproduction Registry from January 2, 2006, to September 3, 2019. The exposed cohort included embryo transfers from couples in which the male partners had Crohn's disease or ulcerative colitis. The unexposed cohort included embryo transfers in which male partners did not have inflammatory bowel disease. RESULTS For fathers with ulcerative colitis, the adjusted odds ratio for a positive biochemical pregnancy (positive human chorionic gonadotropin) was 1.14 (95% confidence interval [CI], 0.92-1.42), for a clinical pregnancy (positive vaginal ultrasonography at 7-8 weeks) was 0.91 (95% CI, 0.59-1.40), and for a live birth was 0.99 (95% CI, 0.71-1.60). For fathers with Crohn's disease, the adjusted odds ratio for a biochemical pregnancy was 0.83 (95% CI, 0.63-1.09), for a clinical pregnancy was 0.58 (95% CI, 0.34-0.97), and for a live birth was 0.88 (95% CI, 0.51-1.55). CONCLUSIONS These findings may indicate that partners of men with Crohn's disease may have an increased risk of early pregnancy loss. Future studies should confirm these results and examine the impact of paternal medications, paternal disease activity, and other factors associated with chronic inflammatory bowel disease.

[PMID: 36640151 DOI: 10.1111/andr.13385] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2022] [Revised: 12/18/2022] [Accepted: 01/09/2023] [Indexed: 01/15/2023]
Abstract
BACKGROUND The increase in paternal age and the percentage of births after assisted reproductive technologies (ART) may have consequences on offspring and society's position regarding access to ART must be questioned. Most countries recommend limiting ART to men under 60 years. What is the rationale for this threshold? OBJECTIVE This systematic review assesses scientific arguments to establish links between paternal age, male fertility, and offspring health. MATERIAL AND METHODS Using the PRISMA guidelines, this systematic review of the literature analyzed 111 articles selected after screening PubMed, ScienceDirect, and Web of Science for articles published between January 1, 1995 and December 31, 2021. RESULTS A strong correlation was highlighted between advanced paternal age and a decrease of some sperm parameters (semen volume and sperm motility) and infant morbidity (exponentially increased incidence of achondroplasia and Apert syndrome, and more moderately increased incidence of autism and schizophrenia). The impact of paternal age on pregnancy and fetal aneuploidy rates is more controversial. No association was found with spontaneous abortion rates. DISCUSSION AND CONCLUSION The scientific parameters should be explained to older parents undergoing ART. And for countries that discuss a limit on paternal age for access to ART, the debate requires consideration of social and ethical arguments.

Abstract
Pregnancy loss has multifactorial causes, and the maternal risk factors are the most investigated. Therefore, this review investigates the current literature regarding the effect of paternal health on pregnancy loss. This review is conducted according to the PRISMA guidelines. The electronic databases PubMed and Medline were the primary sources of information. The online tool covidence.org was used for the screening process. The Newcastle-Ottawa Scale was used for assessment of risk of bias across the non-RCT (Randomized Controlled Trials) included studies. Six cohort studies and one randomised clinical trial were included for assessment in this review. Especially three large retrospective studies reported that circulatory paternal health issue, increasing metabolic syndrome diagnoses and paternal age was significantly associated with a higher risk of pregnancy loss. Lower pregnancy loss was also found in couples with diabetes in the man compared to couples without diabetes. One study suggests a connection between varicocelectomy and improved sperm DNA fragmentation and lower abortion rate. This review confirms that paternal age, somatic health and particularly health regarding cardiovascular and metabolic disease are associated positively with risks of pregnancy loss. However, further research may lead to evidence, which are more conclusive.

Abstract
BACKGROUND Low semen quality often obligates the use of assisted reproductive technology; however, the association between semen quality and assisted reproductive technology outcomes is uncertain. OBJECTIVES To further assess the impact of semen quality on assisted reproductive technology outcomes. MATERIALS AND METHODS A retrospective cohort study was carried out at a single academic reproductive medicine center (January 2012-December 2018). Patients undergoing at least one assisted reproductive technology cycle utilizing freshly ejaculated spermatozoa from the male partner were included. We assessed the association between semen quality (as stratified based on WHO 5th edition criteria), paternal age (< or ≥40), and reproductive/perinatal outcomes. To evaluate the differences in assisted reproductive technology outcomes by semen parameters and age, generalized estimating equations were applied for rates of fertilization, pregnancy, implantation, miscarriage, live birth, blast formation, gestational age, and normal embryo biopsy. RESULTS A total of 2063 couples were identified who underwent 4517 assisted reproductive technology cycles. Average ages of the male and female partners were 39.8 and 37.7, respectively. Lower pregnancy rates were observed in cycles with lower sperm motility (ie <40%; 39.9% vs 44.1%) and total motile count (ie <9 million; 38.3% vs 43.5%). When examining only cycles utilizing Intracytoplasmic Sperm Injection, only a lower motility count was associated with a decline in pregnancy rate (39.1% vs 44.9%). No association was identified between semen quality and gestational age or birth weight. Paternal age was not associated with ART outcomes. However, among assisted reproductive technology cycles in women <40, aneuploidy rate was higher for older men (P < .001). In cycles with women >40, no association between aneuploidy and male age was identified. DISCUSSION Sperm motility is associated with pregnancy rates, while other semen parameters are not. In cycles in women <40, paternal age is associated with embryo aneuploidy rate. CONCLUSION Paternal factors are associated with assisted reproductive technology outcomes, and future studies should explore mechanisms by which semen quality is associated with assisted reproductive technology outcomes.

Abstract
OBJECTIVE To investigate the prevalence and effects of medical comorbidities on spermatogenesis and to determine whether the treatment of medical comorbidities effectively improves spermatogenesis. DESIGN Single-center case-control study. SETTING University hospital. PATIENT(S) A total of 3,328 infertile men and 452 men with normal results on semen examination, with mean age of 35 years. INTERVENTION(S) Hormonal and spermatogenic parameters were compared between the men with and without medical comorbidities. For the men diagnosed with medical comorbidities during the infertility evaluation, semen parameters were compared between those who did and did not undergo treatment of the comorbidities. MAIN OUTCOME MEASURE(S) Rate of comorbidity, relationship between infertility and comorbidity, comorbidity treatment on total motile sperm count. RESULT(S) The prevalence of comorbidities was significantly higher in the infertile men (21.7%) than in the fertile men (9.1%), particularly for hypertension (17.8%), hyperlipidemia (5.9%), hyperuricemia (5.2%), and skin disease (3.0%). Among the infertile men, the reproductive functions were aberrant in the men with comorbidity compared with those without comorbidity. After treatment for comorbidities, a significant increase was observed in the total motile sperm count compared with both the baseline values and with the poorly controlled men. A multivariate analysis showed that varicocele and comorbidity treatments were independent predictors of an improved total motile sperm count, with odds ratios of 2.895 and 2.057, respectively. CONCLUSION(S) Medical comorbidities are associated with impaired sperm production. Male infertility evaluation offers not only specific therapy to improve semen parameters but also therapy for nonspecific medical comorbidities, which may benefit general health status and spermatogenesis restoration.

Abstract
Infertility affects up to 12% of all men, and sexual dysfunction occurs frequently in men of reproductive age, causing infertility in some instances. In infertile men, hypoactive sexual desire and lack of sexual satisfaction are the most prevalent types of sexual dysfunction, ranging from 8.9% to 68.7%. Erectile dysfunction and/or premature ejaculation, evaluated with validated tools, have a prevalence of one in six infertile men, and orgasmic dysfunction has a prevalence of one in ten infertile men. In addition, infertile men can experience a heavy psychological burden. Infertility and its associated psychological concerns can underlie sexual dysfunction. Furthermore, general health perturbations can lead to male infertility and/or sexual dysfunction. Erectile dysfunction and male infertility are considered proxies for general health, the former underlying cardiovascular disorders and the latter cancerous and noncancerous conditions. The concept that erectile dysfunction in infertile men might be an early marker of poor general health is emerging. Finally, medications used for general health problems can cause sperm abnormalities and sexual dysfunction. The treatment of some causes of male infertility might improve semen quality and reverse infertility-related sexual dysfunction. In infertile men, an investigation of sexual, general, and psychological health status is advisable to improve reproductive problems and general health.
