Andrology Lab Corner* Receptors in Spermatozoa: Are They Real?
Sperm develop in the seminiferous tubules of testes following a complex developmental process called spermatogenesis. A series of morphologic remodeling occurs during spermiogenesis before the sperm are released into the lumen of the tubules by spermiation (Eddy and O’Brien, 1994). Mammalian testicular spermatozoa are relatively nonmotile and incapable of fertilizing an ovum. In most species, s...
متن کاملSurgical management of nonobstructive azoospermia
Nonobstructive azoospermia (NOA) is characterized by the complete absence of sperm in the ejaculate due to testicular failure. The evaluation and management of patients with NOA offer a challenge to the reproductive urologist. In the era of in vitro fertilization with intracytoplasmic sperm injection, surgical sperm extraction techniques can afford men with NOA biologic paternity. To provide a ...
متن کاملControversies in the management of nonobstructive azoospermia.
The fertility potential of patients with nonobstructive azoospermia (NOA) depends on sperm extraction from the tissue sample and then in vitro fertilization with intracytoplasmic sperm injection (IVF/ICSI). Unfortunately, there is no consensus regarding predictors that can identify nonobstructive azoospermic men with a potentially high yield at the time of sperm extraction. This article analyze...
متن کاملClinical management of infertile men with nonobstructive azoospermia
The clinical management of men with nonobstructive azoospermia (NOA) seeking fertility has been a challenge for andrologists, urologists, and reproductive medicine specialists alike. This review presents a personal perspective on the clinical management of NOA, including the lessons learned over 15 years dealing with this male infertility condition. A five-consecutive-step algorithm is proposed...
