the role of androgen in ejaculation

Ejaculation is the final link of the male sexual function chain "Libido--Erection--Penetration--Achievement of Climax--Ejaculation". Each link is highly androgen-dependent.

The production of a normal volume of seminal fluid requires the presence of seminal vesicles and the maintenance of their secretion by androgens.

Failure of ejaculation may be classified into I. Deficiency of production of seminal fluid from (1) Absence of seminal vesicles or (2) Androgen deficiency from (a) Pituitary dysfunction or (b) Testicular interstitial-cell failure from a number of causes. Correction of androgen deficiency usually restores ejaculation.
