From the article:
"The findings suggest that in contrast to prior meta-analyses, semen quality in most US men may be more stable than previously thought and may provide further reassurance against an impending epidemic of male factor infertility in fertile men in future generations."
This review also found that some subcultures (like bears) have received substantial research attention, while many others have been studied very little. The authors argue that future research needs to better capture the diversity of LGBTQ+ communities instead of treating men who have sex with men as a single, homogeneous group.
Religiosity positively predicted having more children, but the effect was relatively weak.
There were also different patterns across racial groups. For example, the link between political orientation and fertility rates held only for white Americans, but not for black Americans.
However, the association between women’s higher earnings and relationship dissolution was noticeably stronger among couples raising children. Female-breadwinner couples with children were 49% more likely to separate than male-breadwinner couples, whereas childless female-breadwinner couples were 23% more likely to separate than their male-breadwinning counterparts.
This finding suggests that balancing work and family responsibilities may place greater strain on relationships when women have higher earnings, perhaps because household responsibilities remain unevenly shared.
Men and women differed in how they felt about their sexual debut, with women perceiving the timing as less acceptable than men. However, it is important to note that men and women did not differ in their average age of sexual debut. So despite beginning to have sex at around the same age, men and women reported very different feelings about it.
Those who were more religiously involved perceived their sexual debut as less acceptable, yet they waited longer to begin having sex. Even when accounting for differences in age of sexual debut, religious involvement was linked to feeling less positively about it.
Asexual participants had similar rates of loneliness regardless of whether they were single, in an unsatisfying relationship, or in a satisfying one. The typical mental health advantages linked to romantic pairings seemingly did not translate to asexual respondents.
Women were significantly more likely than men to report worrying about their sex drive.
Relationship status played a role in these concerns as well. Participants who were in relationships, particularly those in relationships lasting between one and fifteen years, were more likely to report low libido and express worry about it.
Of those with nonconsensual paraphilic interests, 30% reported being distressed by their sexual fantasies or desires, with pedophilic interests being linked to the highest rates of distress.
Among those who were distressed, help-seeking behaviors were rare, with only 7% reporting that they sought help in the past 5 years.
Not surprisingly, Transparent Partners exhibit the most relationship satisfaction, secure attachment, and lowest levels of Dark Triad traits.

Antagonistic Strategists report the lowest satisfaction and the highest levels of insecure attachment and Dark Triad traits.
