Effects of semen storage and separation techniques on sperm DNA fragmentation. To determine the effect of semen storage and separation techniques on sperm DNA fragmentation. Methods: Controlled clinical study. Methods: An assisted reproductive technology laboratory. Methods: Thirty normoozospermic semen samples obtained from patients undergoing infertility evaluation. Methods: One aliquot from each sample was immediately prepared (control) for the sperm chromatin dispersion assay (SCD). Aliquots used to assess storage techniques were treated in the following ways: snap frozen by liquid nitrogen immersion, slow frozen with Tris-yolk buffer and glycerol, kept on ice for 24...
Effects of lower doses of conjugated equine estrogens and medroxyprogesterone acetate on endometrial bleeding. To evaluate vaginal bleeding profiles with lower doses of conjugated equine estrogens (CEE) and medroxyprogesterone acetate (MPA) as continuous combined therapy. Methods: The Women's Health, Osteoporosis, Progestin, Estrogen (Women's HOPE) study, a randomized, double-blind, placebo-controlled trial. Methods: Study centers across the United States. Methods: Two thousand six hundred seventy-three healthy, postmenopausal women. Methods: Women received CEE, 0.625 mg/d; CEE, 0.625 mg/d, plus MPA 2.5 mg/d; CEE, 0.45 mg/d; CEE, 0.45 mg/d, plus MPA, 2.5 mg/d; CEE 0.45 mg/d, plus MPA, 1.5 mg/d; CEE, 0....
Horse and marmoset monkey sperm bind to the zona pellucida of salt-stored human oocytes. The present study demonstrates that horse and marmoset monkey sperm can bind to the human zona of salt-stored oocytes that failed to fertilize in vitro. Marmoset monkey sperm are also able to penetrate the salt-stored human zona. In contrast, human sperm do not bind to the zona of either horse or marmoset monkey oocytes. These results suggest that human sperm binding to the zona pellucida is more strictly species-specific than it is for horse and marmoset monkey sperm. In contrast, horse and marmoset monkey sperm contain receptors recognized by the human zona.
Pregnant mare’s serum gonadotropin. IV. Induction of premature labor by pregnant mare’s serum gonadotropin and its prevention by using clomiphene or indomethacin. The administration of pregnant mare's serum gonadotropin (PMSG), 30 IU on day 18 of pregnancy, resulted in premature labor in rats. However, this abortifacient efficacy of PMSG was not demonstrable when a simultaneous injection of progesterone, clomiphene, or indomethacin was scheduled, thus suggesting that the action of PMSG is medicated by the estrogen-stimulated release of prostaglandin. The termination of pseudopregnancy in bilaterally hysterectomized rats by PMSG and its reversal by indomethacin revealed that the inhibition of luteal function by PMSG does not require the presence of a ute...
Scanning electrons and light microscopy of the equine seminiferous tubule. Changes within the equine seminiferous tubules during the cycle of the seminiferous epithelium were studied light and scanning electron microscopy (SEM). Once observed with SEM, tubules were sectioned and staged using light microscopy. As viewed by SEM, the weblike, spongy cytoplasm of germ cells or Sertoli cells in stages I and II extended over the entire height of the germinal epithelium. The cytoplasm of the basal portion of the germinal epithelium in stages III to VIII was similar to that in stages I and II. However, the cytoplasm which occupied the luminal third of the epithelium in stage...
Effect of centrifugation and seminal plasma on motility and fertility of stallion and bull spermatozoa. The effect of centrifugation of diluted and undiluted semen on equine and bovine spermatozoan motility and fertility was examined, as was the effect of seminal plasma and dilution on stallion spermatozoa during incubation before and after freezing. Centrifugation at 370 g or 829 g was not detrimental (P greater than 0.05) to prefreeze or postfreeze motility if a final concentration of 10% seminal plasma was present. A reduction of seminal plasma from 10% to 2% significantly (P smaller than 0.05) reduced motility. A centrifugal force of 956 g significantly reduced prefreeze but not postfreeze m...
