Abstract

Mammalian diploid embryos are produced by fusion (fertilization) of specialized germ cells (gametes) from the male and female. The definitely differentiated male germ cells, the spermatozoa, gain the fertilizing ability after maturation in the epididymis. Therefore, under in vivo and conventional ...

Abstract

Females of strain ICR were inseminated 1.5 h after ovulation with spermatozoa from DBA/2N, CF1 or C57BL/6N ♂♂, using sperm concentrations of 2 × 106 to 8× 106/µl. Eggs recovered from ♀♀ killed at intervals after insemination were examined for evidence of penetration. The intervals from insemination ...

Abstract

Experiments involving repeat insemination of zona-free ova indicated that after fertilization the ova plasma membrane is altered such that sperm binding to the membrane is blocked, except in the region of the 2nd polar body. Activation of the ova with ethanol or strontium chloride did not result in ...

Abstract

Females aged about 21 days were injected with 2.5 IU PMSG followed 48 h later by 10 IU HCG. They were then mated, and were killed 68 h after HCG. For outbred N:NIH(S) albino, N:NIH(S)-B black and N:GP(S) ♀♀, and C57BL/6N and C3H/HeN MTV- ♀♀, the percentage from which embryos were recovered was 59,...

Abstract

From work on the fertilization rate in mouse oocytes incubated for 1-8 h in medium with different sperm concentrations (1 × 105 and 5 × 105), it was found that fertilization rate increased with incubation period. The best results were obtained with cumulus-free oocytes incubated for 8 h in medium...

Abstract

Single blastomeres were obtained by the disaggregation of 4-cell fertilised ova by various freezing treatments or by versene treatment, and were cultured in vitro. These blastomeres retained the ability to develop up to the blastocyst stage.

Abstract

In order to minimise the experimental costs associated with maintaining the large breeding colonies necessitated by the unreliable breeding behaviour of mice, the effects on reproductive performance of using AI, ovum transfer, and the artificial induction of pseudopregnancy in recipient females...

Abstract

The fertilising ability of superovulated mouse ova was evaluated after A.I. (vaginal route) and fertilization in vitro in explanted ampullar parts of the oviducts, and was compared with the fertility rate of superovulated ova after copulation. The number of fertilized ova was also studied after...

Abstract

90 KE strain ♀ mice aged 9-12 wks. were artificially inseminated about 18 hrs. after the injection of HCG to induce ovulation. The ♂♂ that provided the spermatozoa were of 2 genotypes: inbred KE and crossbred F1 (KP ♂ x KE ♀). The spermatozoa were either epididymal or collected from the uteri of...

Abstract

Prepuberal ♀ mice were hormonally induced to ovulate and were artificially inseminated with spermatozoa that had been stored in vitro from 2 to 24 hrs. No difference was found in fertilising ability due to storing spermatozoa for different periods of time. Inseminations were performed at various...
