Objective: To review the most clinically significant genetic disorders associated with severe
oligospermia and azoospermia in males, and to present recommendations for the genetic …

Microdissection testicular sperm extraction (microTESE) is considered the gold standard
method for surgical sperm retrieval among patients with non-obstructive azoospermia …

Spermatogenesis is a dynamic developmental process that includes stem cell proliferation
and differentiation, meiotic cell divisions and extreme chromatin condensation. Although …

Featuring over 600 full-color illustrations, the Third Edition of this definitive reference
provides comprehensive, current, and authoritative coverage of the entire spectrum of …

The incidence of invasive testicular cancer is increased in men with a history of
cryptorchidism. Previous studies based on relatively small series indicated that the risk of …

Testicular and epididymal spermatozoal reserves were determined for 11 healthy men, a
vasectomized man and 12 other men. For healthy men testis weight (19 testes) averaged …

biopsy from the contralateral testis and/or semen and hormone analyses after orchidectomy …

Background At present, one out of six couples is infertile, and in 50% of cases, infertility is
attributed to male infertility factors. Genetic abnormalities are found in 10%‐20% of patients …

Age-related changes in daily sperm production (DSP) and testicular weights were
investigated in paired testes from 89 men aged 21–50 years and 43 men aged 51–80 years …

Based on enumeration of maturation-phase spermatids in testicular homogenates from adult
men and rats, daily sperm production per gram of testicular parenchyma (DSP/g) was almost …
