'''పౌరుష గ్రంథి''' (Prostate gland) శుక్రకోశ పీఠభాగంలో ఉంటుంది. ఇది [[ప్రసేకం]]లోకి అనేక నాళాల ద్వారా తెరచుకొంటుంది. ఇది స్రవించే క్షార పదార్ధం శుక్రకణాలను ఉత్తేజితం చేస్తుంది. ఇది [[శుక్రద్రవం]]లో అధిక భాగాన్ని ఏర్పరుస్తుంది.

The function of the prostate is to secrete a slightly acidic fluid, milky or white in appearance,<ref>

</ref>. Semen is made alkaline overall with the secretions from the other contributing glands, including, at least, the seminal vesicle fluid . The alkalinity of semen helps neutralize the acidity of the vaginal tract, prolonging the lifespan of sperm. The alkalinization of semen is primarily accomplished through secretion from the seminal vesicles.<ref>

</ref> The prostatic fluid is expelled in the first [[ejaculate]] fractions, together with most of the spermatozoa. In comparison with the few spermatozoa expelled together with mainly seminal vesicular fluid, those expelled in prostatic fluid have better [[motility]], longer survival and better protection of the genetic material (DNA).
The prostate also contains some [[Smooth muscle tissue|smooth muscle]]s that help expel semen during [[ejaculation]].
