A groundbreaking study from University College London (UCL) suggests that male masturbation could improve reproductive success and reduce the risk of sexually transmitted infections (STIs).
The research highlights several evolutionary benefits of self-pleasure among male primates, including humans:

1. Enhanced Fertilization Chances:
Masturbation increases arousal before mating
potentially leading to successful reproduction.
2. Improved Sperm Quality:
Ejaculation helps eliminate low-quality semen
leaving fresher
healthier sperm available for mating
3. Reduced STI Risk:
This behavior may decrease the likelihood of contracting sexually transmitted infections
It helps by increasing arousal before sex, which can improve the chances of successful fertilization. Additionally, ejaculation after masturbation clears out older, low-quality sperm, ensuring that fresh, healthy sperm is available during mating.
The findings also suggest that masturbation is an evolutionary trait present in both wild and captive primates. Researchers analyzed over 246 studies, 150 questionnaires, and expert communications to understand its biological and evolutionary significance.
While the benefits for males are clear, the evolutionary purpose of female masturbation remains less defined, according to lead researcher Dr. Matilda Brindle.
Lead researcher Dr. Matilda Brindle remarked, “Our findings provide significant insights into the evolutionary functions of masturbation, shedding light on a behavior that’s both common and misunderstood.”
The study, published in Proceedings of The Royal Society B, analyzed data from 246 academic papers, 150 questionnaires, and personal communications with zookeepers and primate experts. The findings suggest masturbation has deep evolutionary roots, likely present in the common ancestor of humans and other primates.
