background: stimulatory therapy with gonadotrpins is an effective treatment to induce spermatogenesis in men with idiopathic hypogonadotroptic hypogonadism (ihh). the aim of this study was to assess the effectiveness of human chorionic gonadotropin / human menopausal gonadotropin on hypogonadotropic infertile men. materials and methods: this study included fifty-six azoospermic infertile men wi...
AIM To evaluate for the first time the frequency of Y chromosome microdeletions and the occurrence of the partial deletions of AZFc region in Moroccan men, and to discuss the clinical significance of AZF deletions. METHODS We screened Y chromosome microdeletions and partial deletions of the AZFc region of a consecutive group of infertile men (n = 149) and controls (100 fertile men, 76 normosp...
OBJECTIVE To study the meiotic abnormalities during prophase I in an azoospermic man with t(1;21) reciprocal translocation. DESIGN Analysis of synapses, recombination, and transcription inactivation in a testicular biopsy sample. SETTING Research laboratory. PATIENT(S) One azoospermic patient with t(1;21) and five men with normal spermatogenesis. INTERVENTION(S) Immunostaining for SCP3,...
UNLABELLED The incidence of vasal injury during inguinal herniorrhaphy is estimated at 0.5%. We sought to assess the patency rates and long-term fertility outcome after microsurgical repair of vasal obstruction related to prior inguinal herniorrhaphy. METHODS Twenty procedures were performed on 13 men diagnosed with infertility and vasal injury secondary to previous inguinal herniorrhaphy. Ei...
BACKGROUND & OBJECTIVES Genetic factors contribute about 10 per cent of male infertility. Among these, genes in azoospermia factor (AZF) region including AZFa, AZFb, AZFc and AZFd on the long arm of Y chromosome are considered most important for spermatogenesis. Deletions in these regions are thought to be involved in some cases of male infertility associated with azoospermia or oligozoospermia...
Experimental studies in laboratory animals have shown that successful conception can be achieved by fertilizing oocytes with immature male germ cells. This gave rise to the concept that immature germ cells recovered from the testes of azoospermic men with maturation arrest may be used for assisted reproduction. However, in contrast to using germ cells recovered from healthy animals, clinical ap...
