2010/1/12
Aim: To compare the semen parameters between pregnant and nonpregnant couples with male factor infertility during intrauterine insemination (IUI). Materials and Methods: The study included a total of ...
Vasopressin receptors in human seminal vesicles：identification, pharmacologic characterization, and comparison with the vasopressin receptors present in the human kidney
Vasopressin receptors human seminal vesicles identification pharmacologic characterization
2009/2/23
Because of the presence of a high density of vasopressin receptors in the epithelial cells of porcine seminal vesicles similar to the V2 vasopressin receptors of renal tubules, human seminal vesicle...
Comparison between proteinases of human seminal plasma and of sperm origin
proteinases human seminal plasma sperm origin
2009/2/23
A comparison of the alkaline proteinase activity of human seminal plasma, the seminal non-gamete cellular material and spermatozoa was made by gelatin-sodium dodecyl sulfate-polyacrylamide gel elect...
Comparison of a direct and indirect ELISA for quantitating antisperm antibody in semen
direct indirect ELISA quantitating antisperm antibody semen
2009/2/23
A direct and an indirect quantitative ELISA for antisperm antibody were compared using the spermatozoa and cell-free seminal fluid of 66 infertile males. The normal concentration of sperm binding immu...
Comparison of the penetration ability of human spermatozoa into bovine cervical mucus and zona-free hamster eggs
penetration ability human spermatozoa bovine cervical mucus zona-free hamster eggs
2009/2/20
In vitro bovine cervical mucus (BCM) penetration tests, sperm penetration assays (SPA) using zona-free hamster eggs, and routine semen analyses were performed on a total of 136 freshly collected sem...
Analysis of human sperm function following exposure to the ionophore A23187. Comparison of normospermic and oligozoospermic men
A23187 sperm motility fertilization ohgozoospermia
2009/2/20
Time exposure photomicrography and interspecific in vitro fertilization techniques have been used to compare the responses to the divalent cation ionophore A23187 of spermatozoa from normal fertile an...
Comparison of glycerol and a zwitter ion buffer system as cryoprotective media for human spermatozoa. Effect on motility, penetration of zona-free hamster oocytes, and acrosin/proacrosin
spermatozoa human cryopreservation
2009/2/20
This study compared the cryoprotective effect of glycerol with that of a zwitter ion buffer system (TESTCY). Spermatozoa that are cryopreserved in the presence of glycerol possess a somewhat highe...
The effect of testicular x-irradiation on spermatogenesis in man. A comparison with the mouse
irradiation spermatogenesis testicular
2009/2/20
Existing data concerning the effects of x-irradiation on spermatogenesis in man were analyzed and the results were compared to published data on the mouse. Testicular x-irradiation produced a transi...
Comparison of Prostatic Response to Pituitary Grafts in Castrate Rats Treated with Testosterone or Dihydrotestosterone
prostate prolactin testosterone dihydrotestosterone
2009/2/19
To understand further the effect of prolactin (PRL) on prostatic growth, the present study was undertaken to determine if the augmentation of testosterone (T)-stimulated growth by PRL is mediated ...
Endogenous Steroids in the Rat Seminiferous Tubules. Comparison of the Stages of the Epithelial Cycle Isolated by Transillumination-Assisted Microdissection
androgens seminiferous tubules rats stages of spermatogenesis transillumination
2009/2/19
A microdissection procedure is described that allows the isolation of segments of rat seminiferous tubules in different stages of the epithelial cycle. This procedure is based on spermatogenic sta...
