Compared with both the 36 breastfed comparison men and the 18 formula-fed exposed men, the 21 breastfed exposed men also had increased follicle-stimulating hormone and decreased inhibin B, a hormone pattern previously shown to be a marker for impaired spermatogenesis.
Spermatogenesis couples genetic recombination and meiosis with germ cell proliferation and differentiation, culminating in the release of spermatozoa from the testis.
Most of the candidate genes involved in spermatogenesis have been mapped to the proximal long arm of the Y chromosome (Yq11) and are arranged in azoospermia factor (AZF) region including AZFa, AZFb, and AZFc sub regions (5).
