Reduction of Prostate Cancer Risk: Role of Frequent Ejaculation-Associated Mechanisms.

Area of Science:

• Urology
• Oncology
• Reproductive Biology

Background:

• Prostate cancer (PCa) is a significant global health concern, with incidence rising worldwide.
• Several factors influence PCa risk, including age, genetics, lifestyle, and chemoprevention.
• The prostate gland's function is regulated by androgens, particularly 5α-dihydrotestosterone (5α-DHT), via androgen receptors (AR).

Purpose of the Study:

• To review the potential mechanisms by which frequent ejaculation may reduce the risk of prostate cancer.
• To explore the physiological processes linking ejaculation to prostate homeostasis and cancer prevention.

Main Methods:

• This study is a review of existing literature on prostate cancer, male reproductive function, and androgen regulation.
• It synthesizes findings related to the androgen-dependent mechanisms governing prostate growth and function.

Main Results:

• Ejaculation is linked to reproductive functions and the regulation of androgen levels.
• The binding of 5α-DHT to AR initiates a cascade affecting androgen-regulated genes, crucial for prostate homeostasis.
• Frequent ejaculation may contribute to reducing PCa risk by influencing these androgen-dependent pathways.

Conclusions:

• Frequent ejaculation, in the absence of risky sexual behaviors, is proposed as a potential strategy for prostate cancer prevention.
• Understanding the mechanisms of ejaculation's impact on prostate health could lead to novel preventative approaches for PCa.
