Cryptorchidism is the most frequent congenital birth defect in male children (2–4% in full-
term male births), and it has the potential to impact the health of the human male. In fact …

Male factor infertility accounts for about half the cases of couple infertility and in around 50%
of cases its etiology remains unknown. Molecular genetic techniques have unveiled a …

OBJECTIVE: To reassess the predictive value of detecting sperm cells in men with AZFb or
AZFb-c deletions. DESIGN: Retrospective analysis of previously reported men with AZFb or …

BACKGROUND The prevalence of chromosomal abnormalities is assumed to be higher in
infertile men and inversely correlated with sperm concentration. Although guidelines advise …

BACKGROUND: This study was carried out to evaluate whether bilateral orchidopexy
represents a poor or good prognostic factor in azoospermic men undergoing testicular …

Background Cryptorchidism is the most frequent congenital disorder in male children;

Обследованы 105 мужчин, больных туберкулезом легких, при поступлении и через 3, 6
мес. лечения, из них 62-пациенты с инфильтративным туберкулезом легких (ИТЛ), 43 …

Background Cytogenetic and molecular studies of azoospermic and oligozoospermic males
have suggested the presence of azoospermia factors (AZF) in the Y chromosome. Deletion …

BACKGROUND A specific type of partial AZFc deletion, called 'gr/gr'deletion, was recently
proposed as genetic risk factor for spermatogenic impairment and testis cancer. Since both …

The aim of this study was to establish the prevalence of Y chromosomal microdeletions in
infertile Tunisian men. Three groups of infertile men, 65 normospermic, 53 oligozoospermic …
