Evidence for a role of cyclooxygenase（prostaglandin synthetase）and prostaglandins in the sperm acrosome reaction and fertilization
spermatozoa fertilization acrosome reaction cyclooxygenase prostaglandin inhibitor
2009/2/23
Three cyclooxygenase (prostaglandin synthetase) inhibitors, indomethacin, phenylbutazone, and oxyphenbutazone, decreased fertilization in vitro when mixed with capacitated mouse spermatozoa before a...
Correlation between in vitro fertilization and human sperm density and motility
Correlation fertilization human sperm density motility
2009/2/23
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...
Improvement in the quality and fertilization potential of a human sperm population using the rise technique
fertilization potential human sperm population rise technique
2009/2/23
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 ...
Correlation between human sperm swelling in hypoosmotic medium（hypoosmotic swelling test）and in vitro fertilization
human sperm hypoosmotic medium（hypoosmotic swelling test） vitro fertilization
2009/2/23
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...
Effect of Fatty Acids on Fertilization and Development of Mouse Embryos In Vitro
fertilization embryos fatty acids bovine serum albumin
2009/2/19
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...
Ca2+ Is Required for Mouse Sperm Capacitation and Fertilization In Vitro
capacitation acrosome reaction whiplash motility A23187 fertilization in vitro calcium
2009/2/19
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 ...
In Vitro Sperm Capacitation and In Vitro Fertilization with Normal Development in the Rabbit
sperm capacitation in vitro fertilization embryo culture embryo transfer spermatozoa oocytes rabbit
2009/2/19

Fertilization of Mouse Eggs In Vitro
in vitro fertilization penetration of zona pellucida 3-quinuclidinyl benzilate acrosome reaction sperm binding to zonae mouse sperm mouse eggs inhibition of zona binding
2009/2/19
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...
Characterization of Cholinomimetic Agents that Inhibit In Vitro Fertilization in the Mouse
sperm binding cholinomimetics
2009/2/19
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...
Role of Hyaluronidase in Fertilization: The Antifertility Activity of Myocrisin, a Nontoxic Hyaluronidase Inhibitor
myocrisin hyaluronidase inhibitor fertilization contraception
2009/2/18
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...
Evidence of proacrosin molecule abnormality as a possible cause of low acrosin activity and unexplained failure of fertilization in vitro
