388. (d) Spermatogenesis starts at puberty under
the influence of gonadotrophins secreted from the
anterior pituitary gland.

The primary spermatocyte undergoes first meiotic
division to form two secondary spermatocytes. The
total diploid number of chromosomes (46) of
primary spermatocyte are reduced to half (23) by
the first meiotic division.

Therefore, each secondary spermatocyte contains
only 23 chromosomes. They undergo a second
maturation meiotic division.

This is similar to mitotic division and the number of
chromosomes remains the same. After finishing
secondary meiotic division, each secondary
spermatocyte produces two spermatids. This may
produce a total of four spermatids from two
secondary spermatocytes. These four spermatids
may convert into sperm after maturation.
