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...
In this study, the frequency and titers of serum antibodies to Chlamydia trachomatis in fertile and subfertile subjects and possible correlations between a positive serology and the values of conven...
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...
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 ...
A group of 598 allegedly fertile men requesting vasectomy were investigated; varicocele was found in 97 (16.2%) of these men. The mean ages and age distributions of men with and without varicocele w...
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...
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...
Recent evidence in our laboratory suggests that the cause of idiopathic subfertility/infertility in breeding stallions may originate in the testes at the luteinizing hormone (LH) receptor or postr...
Mammalian sperm that have completed capacitation are capable of undergoing the acrosome reaction in response to a number of biological and chemical stimuli. In the present report, we have investig...
Changes in nuclear size, shape, and chromatin texture during spermiogenesis and epididymal transport of human sperm were recently analyzed using transmission electron microscopy (TEM) image cytome...
The goals of this study were to determine the effect of the nonionic detergent, Triton X-100, on the recovery of acrosin in the clinical assay (Kennedy et al, 1989), since previous investigations ...
Five fertile and five subfertile stallions were treated with a single intravenous injection of saline the first week followed by a single intravenous injection of varying doses of gonadotropin-rel...
Seasonal effects on hormonal and seminal parameters in subfertile stallions have not been well documented and could provide information that is needed to understand the underlying endocrine mechan...
Human seminal plasma proteins from fertile and infertile men were fractionated by electrophoresis. The amounts of three Coomassie-stained protein bands were measured by densitometry. Their relativ...
The authors examined the value of sperm creatine-kinase (CK) activity parameters to predict sperm fertilizing potential of oligospermic men. Two patient groups from our intrauterine insemination pro...
