Male Reproductive Health - study of a sperm donor population

Abstract

Objective: Every individual has the right to a safe and satisfactory sex and reproductive life. Therefore, several countries have made efforts to make Reproductive Health resources available to their populations. However, few results have been published regarding the policies implemented in Portugal. This study looked into the reproductive health status of the Portuguese male population.Methods: Sperm donor candidates from the Portuguese Public Gamete Bank registered between 2011 and 2018 were included in the study. Spermogram findings were evaluated with respect to sociodemographic and risk factors.Results: This is the first study performed in this population. We found that sperm quality has decreased throughout the last nine years, and that spermatozoa progressive motility is inversely correlated with the body mass index. An association between drug use and decreased sperm pH was also found.Conclusions: Changes in sperm quality have important consequences in male fertility. Most of the identified causes of decreased sperm quality are modifiable factors and should therefore be addressed since an early age.

Cut‐off value for anti‐Müllerian hormone in the diagnostic criteria for polycystic ovary syndrome in the Japanese population

“…Serum AMH levels of them were similar compared to those of healthy patients in other populations. 42,43 Furthermore, our multiple regression analysis showed that the serum AMH level is independently affected by the presence of PCOS and by age, in agreement with our previous report. 41 The number of follicles in every growing stage tends to be greater in women with PCOS than in healthy women, [44][45][46] which is remarkable in the small antral and pre-antral follicle stages.…”

“…In this study, the control group consisted of patients that initiated ART in the absence of ovulatory disorders. Serum AMH levels of them were similar compared to those of healthy patients in other populations 42,43 . Furthermore, our multiple regression analysis showed that the serum AMH level is independently affected by the presence of PCOS and by age, in agreement with our previous report 41 .…”

Sperm parameters in Israeli transgender women before and after cryopreservation

“…Additionally, it was possible to compare the semen parameters of transgender women with the semen parameters of a control group comprised of sperm donor candidates. The use of candidates for sperm donation with unknown fertility status allows the reduction of selection bias, as it should reflect a healthy sample of the population 34,35 that more accurately represents the local population compared to the WHO references that depict the lower range of the fertile population. Furthermore, our study demonstrates the expected decline in sperm parameters after thaw for transgender female preservation to a greater extent compared to our control.…”
