Background: Oocyte cryopreservation is an important part of modern fertility treatment. The effect of vitrification on the fertilization and developmental rates of embryo is still a matter of debate.
Hydrosalpins (dilatation of Fallpian tube that can be seen by hysterosalpingogeraphy. Laparoscocpy, and in severe cases by sonography) is one of the probable confounding factors of assited – reproduct...
Three cyclooxygenase (prostaglandin synthetase) inhibitors, indomethacin, phenylbutazone, and oxyphenbutazone, decreased fertilization in vitro when mixed with capacitated mouse spermatozoa before a...
The conventional sperm characteristics of density (millions per milliliter) and motility, scored in a semi-subjective way, were correlated with results of an on-going in vitro fertilization and em...
Semen from 63 individuals participating in an in vitro fertilization program was processed using a modified rise technique. Overall normal morphology was significantly improved in the rise (79.2%) as ...
Human ejaculates (n = 83) were analyzed for standard sperm parameters (concentration, motility, and morphology), as well as for the ability of the spermatozoa to react (swell) in a hypoosmotic mediu...
The interaction of protein and fatty acids on the fertilization and preimplantation development of mouse embryos in vitro was investigated. Normal fraction V and fatty-acid-free bovine serum albumin...
The temporal involvement of Ca2+ during mouse sperm capacitation in vitro was examined by releasing sperm into Ca2+-free medium and then introducing Ca2+ (1.80 mM, final concentration) at 30 minute ...
The objective was to obtain in vitro sperm capacitation and fertilization to approximate the normal in vivo processes. Rabbit oocytes from follicles, ovarian surfaces, and oviducts were fertilized...
3-Quinuclidinyl benzilate (QNB) is a potent inhibitor of fertilization of mouse eggs in vitro: it acts by blocking penetration of the zonae by sperm. The time course of this inhibition was examine...
Spermatozoa from the cauda epididymidis of the mouse bind 3-quinuclidinyl benzilate (QNB), a highly specific antagonist of the muscarinic type of acetylcholine receptor; inhibition of in vitro ferti...
Myocrisin, a hyaluronidase inhibitor of low molecular weight, was tested for antifertility activity. In addition, the effect of myocrisin on penetration of the follicle cell layer by spermatozoa w...
The aim of this study was to investigate whether the molecular abnormality of proacrosin is associated with an unexplained failure of in vitro fertilization (IVF) and low acrosin activity in human...
The rat cauda epididymidis receives sympathetic innervation from the inferior mesenteric ganglion (IMG). We have previously demonstrated that surgical removal of the IMG and proximal hypogastric ner...
The objective of this study was to investigate the association of rapid and linear progressive motility in seminal and Percoll-separated sperm with the outcome of intrauterine insemination (IUI) and...
