Spermatozoa with smaller head length and head area were found in ejaculates with the greatest total sperm number (more than 120×109 spermatozoa) than in ejaculates with total number of spermatozoa of 70–90×109. The results of the present study suggest that the number of spermatozoa in an ...
The importance of porcine sperm parameters on fertility in vivo It would be desirable to use semen parameters to predict the in vivo fertilizing capacity of a particular ejaculate. In animal production, an ejaculate is ... S.,Tardif,and,... - 《Theriogenology》 被引量: 228发表: 1999年 The...
We suggest that pooling of two sequential ejaculates from oligozoospermic males is a simple and cost effective method to increase significantly the total number of motile sperm for intrauterine insemination, in vitro fertilization, gamete intrafallopian transfer, or semen cryopreservation. 展开 ...
The number of intromissions required to elicit ejaculation actually decreases for a few days after castration. Therefore, one function of T may be to increase the number of intromissions preceding ejaculation, which would increase the number of sperm in the ejaculate, facilitate sperm transport, ...
A weighted mean difference of 0.17% NR in favor of the 30million was not statistically significant (P>0.05). Measurements were made which included motility, per cent survival, sperm number, and cooling time and correlated with per cent NR on a within treatment split-ejaculate basis. No ...
