Additionally, although the onset of spermatogenesis (spermarche
) was not a focus of this analysis, spermarche
closely reflects the achievement of testis function during male puberty (Kulin et al.
4) At puberty, Baushi (Zaire) boys use numerous plants to prepare their genitals to ensure glandular function and erectile potency, to provoke spermarche, and to effect penile enlargement.
Evans-Pritchard's (1932) account of Azande spermarche implies that, in the absence of a chronological age reckoning, a boy's developmental status was actually measured by the appearance of his ejaculate:
28) Sometime during puberty, perhaps one to three years after spermarche

7% of this group indicated that they were aware spermarche

The evaluation of sperm in urine (spermaturia) has been used previously to assess the age of onset of spermarche
