Male infertility in Kuwait. Etiologic and therapeutic aspects.
OBJECTIVE
To evaluate the pathological patterns associated with male infertility in Kuwait and to characterize treatment outcome after varicocele repair using percutaneous varicocele embolization.


METHODS
We carried out a prospective study of 64 infertile men in Kuwait between 2001 and 2005. All patients included had proven non-obstructive azoospermia or oligospermia (sperm count <20 million/ml). All patients underwent ultrasonographic evaluation of the scrotum. Fine needle aspiration of the testes was performed on all azoospermic patients.


RESULTS
A total of 24 (38%) patients were azoospermic while 40 (62%) were oligospermic. Sertoli- cell-only pattern was the most common cytopathology associated with primary testicular failure. Among the oligospermic patients, 50% had small to moderate varicocele. Spermatic vein embolization resulted in a significant rise in the mean sperm count from 10.6 +/- 3.8 million/ml to 30.2 +/- 6.8 million/ml (p<0.05) in 5 treated oligospermic patients, followed by spontaneous pregnancy in 2 couples. No effect was seen on azoospermic patients.


CONCLUSIONS
From an etiological point of view, we believe that the high incidence of Sertoli cell-only-syndrome among nationals and residents of a country that underwent a major environmental insult strengthens the chances of an environmental role in the development of this syndrome. From a management point of view, in cultures where in vitro fertilization is either still not widely acceptable or is unaffordable, oligospermia with clinical or subclinical varicocele deserves a trial of a low risk, out patient procedure, namely, spermatic vein embolization that could improve fertility.
