A member asked:

When a boy first ejaculates, does he already have comparable adult sperm count/motility, or does he gradually get there over time, how long?

A doctor has provided 1 answer

Fertile sperm are present during puberty after the hormonal stimulation triggers their formation. The penis is wired to achieve erection from birth on which can be surprising to some. . When spontaneous "nightfall" or erection/semen expulsion in sleep occurs in the teen years it may contain viable sperm.

Dr Rhoads and another doctor agreed

For low sperm count and motility, does it make sense to ejaculate twice for the sample to be used in IUI to increase sperm quantity?
