Intrinsic (mitochondrial) pathway and extrinsic pathway which is done by cell receptors.2 Apoptosis has a significant relation with infertility of men.3 The more immature the testicle, the more apopto...
In order to determine the seminal activity of LDH-C4 and to investigate its correlation with other fertility indexes, we studed total LDH, total CK avtivities, and LDH-C4 in relation to sperm count, m...
The results of routine semen analyses, the zona-free hamster oocyte penetration test, the hypoosmotic swelling test, and semen adenosine triphosphate levels were studied in 66 fertile and 130 infe...
LDH-X, an isoenzyme of lactate dehydrogenase specific for germinal epithelium activity, has been measured in the seminal plasma of infertile subjects whose infertility had different origins. In the ...
In both man and animals, changes in Leydig cell structure and function accompany seminiferous tubule damage. In this study of 1745 men attending an infertility clinic, 14% of men with elevated lev...
The presence of motility inhibitors in seminal plasma and within spermatozoa from control and infertile men with poor sperm motility was investigated using demembranated reactivated human spermatozo...
Human seminal plasma contains large amounts of transferrin, which is a protein secreted mostly by Sertoli cells. It has been suggested that the concentration of transferrin may serve as a possible c...
In order to reexamine the hypothesis that a high percentage of infertile men with oligo/azoospermia have androgen resistance due to androgen receptor abnormalities, both whole cell and nuclear uptak...
This study evaluated bromocriptine treatment in nine patients with prolactin secreting adenomas who continued to have elevated circulating levels of prolactin after surgery, and who were interested ...
Free cytoplasmic estradiol receptor was determined in testicular biopsies from six adults showing various primary testicular disorders, and in testicular tissue obtained at autopsy from 18 males of ...
This study was carried out to evaluate the morphology of spermatozoa in infertile men with and without varicocele. A series of 285 ejaculates were fully evaluated for seminal volume, sperm count, mo...
Sperm penetration rates in the heterologous ovum penetration test were correlated with results of routine semen analysis in 30 fertile and 50 infertile men. There was no difference in penetration ra...
Thirty-two men with abnormal (less than or equal to 11% penetration) Sperm Penetration (hamster ova) Assay (SPA) results were treated with doxycycline and reevaluated by SPA and seminal fluid analys...
It has been suggested that insulin-like growth factor (IGF)-1 plays an important role in the regulation of spermatogenesis in the testes. In the present study, concentrations of total IGF-1 we...
Interleukin-12 (IL-12) is a unique cytokine that recently has drawn considerable attention because of its immunomodulatory properties and its possible involvement in several normal physiological a...
