These transparent eggs are valuable for studies observing living cells and for biochemical and molecular investigations because the time of fertilization can be accurately fixed, the development of many eggs occurs at about the same rate under suitable conditions, and large quantities of the eggs are obtainable.
Transfer of high sperm numbers at the time of copulation increases the chances of fertilization because of the considerable sperm losses along the female tract, with only a few sperm reaching the site of fertilization in mammals [17].
Thus, cows with either too low (FR-L) or too high (AL-H) insulin and LH stimulation had lesser embryo production after superstimulation because of reduced fertilization rate and increased percentage of degenerate embryos.
(2) That NPP is positively correlated with water quality indexes and crop field ratio suggests increasing NPP is correlated with degradation of water quality, because of the fertilization in croplands.
Quadrupling CO2 increases net primary productivity because of CO2 fertilization effects.
The soil samples were collected in municipality of Remigio, PB (6°59′14.9″ latitude S; 35°48′14.8″ longitude W) because of its fertilization regime.
We interpret this as an adaptation to a shortage of males, because a long life increases the chance of fertilization and/or of finding a high quality partner.
This study cautions that fertilization success is not a perfect predictor of sperm competitive ability, because of the relative nature of the calculation of fertilization success measures.
IVF sometimes includes ICSI to improve the chances of fertilization when the infertility is on the male end, because it eliminates reliance on sperm motility.
On the other hand, because this policy prevents academic investigators from studying in vitro fertilization with funds from the National Institutes of Health, it compromises efforts to learn the fundamental principles of fertilization and to improve the basic technology.
