❄️ :-
Semen is a collection of secretions from the seminal vesicles , prostate gland and Cowper's glands and sperms from testes.
Semen is ejected from the penis during ejaculation.
It provides fluid medium for sperm transmission, nourishes sperms and neutralises the acidity of the urine in the urethra of the male to protect sperms.
