What reproductive role does the prostate play in mammals?

The prostate gland in mammals plays a crucial role in reproductive physiology, primarily through the production of seminal fluid. This fluid is a key component of semen, which serves to nourish and transport sperm during ejaculation. The prostate's secretions contribute to the volume of the ejaculate and provide an appropriate environment for sperm viability and motility within the female reproductive tract.

In addition to helping protect sperm, the prostatic fluid also contains various enzymes and substances that enhance the likelihood of successful fertilization. Notably, the prostate's involvement in reproductive health is significant, as any abnormalities in its function can affect fertility. The other reproductive roles mentioned do not pertain to the prostate; oocytes are produced in the ovaries, hormones are secreted by various glands throughout the body, and the birth process involves different structures such as the uterus and cervix.
