Plasma testosterone, follicle-stimulating hormone (FSH), and luteinizing hormone (LH) levels were measured in the male partners of 69 infertile couples and in 260 allegedly fertile men requesting va...
Azoospermia is the cause of infertility in 8% of infertile male patients. Ten percent of those patients suffer from agenesis of the seminal vesicle (SV) and vas deferens (VD) agenesis. Currently, ...
Weekly intramuscular administration of testosterone esters such as testosterone enanthate (TE) suppresses gonadotropins and spermatogenesis and has been studied as a male contraceptive. For unknown ...
A retrospective study was carried out to determine the prevalence of sex-chromosome mosaicism among azoospermic men and to evaluate the feasibility of using fluorescence in situ hybridization (FISH)...
The aim of the present study was to evaluate the morphology of testicular spermatozoa by 3 different determinants. Sperm cells were obtained and their morphology was evaluated from 27 testicular spe...
The human follicle-stimulating hormone (FSH) receptor (FSHR) gene possesses single nucleotide polymorphisms (SNP) in exon 10, which influence serum FSH levels in women, but not in men. In the presen...
Male infertility is known to be associated with testicular tumors (Honig et al, 1994). In one recent report (Nobert and Goldstein, 2001), at least a 16-fold increase in the risk of testicular cancer, ...
The objective of this study was to evaluate nuclear normality in intracytoplasmic sperm injection (ICSI)-selected epididymal sperm from obstructive azoospermic (OA) patients. We evaluated whether th...
Deletions in the q arm of the Y chromosome result in spermatogenesis impairment. The aim of the present study was to observe the X and Y chromosome alignment in the spermatocytes of men with Y chr...
The differentiation of the urogenital system and the appendicular skeleton in vertebrates is under the control of Homeobox (Hox) genes. It has been shown that this common control of digit and gonad ...
Germ cell-less (GCL) protein is a nuclear envelope protein highly conserved between the mammalian and Drosophila orthologues. In Drosophila, maternal GCL protein is required to establish the germ ...
A multicenter, open-label, randomized efficacy and safety study was performed with combined human chorionic gonadotropin (hCG) and recombinant follicle-stimulating hormone (recFSH) (Puregon®) ...
Genetic factors cause about 10% of male infertility. Azoospermia factors (AZFa, AZFb, AZFc) are considered to be the most important for spermatogenesis. We therefore made an attempt to evaluate the ...
The androgen receptor gene has a polymorphic trinucleotide repeat that encodes a polyglutamine tract in its N-terminal transactivation domain. We started this study in order to find out whether a corr...
The incidence of azoospermia in infertile men is between 5% and 20%, while in the general population, it is about 2% (Jarow et al, 1989; Jarow, 1992). In the past, the main purpose of the evaluation o...
