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.

7% of this group indicated that they were aware spermarche
was going to occur, but that they had received information from no source" (Downs & Fuller 1991, p.
