INTRODUCTION. Aerobic glycolysis is the primary source of ATP in many mammals for sperm motility and capacitation [1, 2].Glycolysable substrates are essential for motility [3, 4], protein tyrosine phosphorylation and hyperactivation associated with capacitation [4–7], and fertilization [8, 9].Conversion of pyruvate to lactate with the …

In the human reproductive process, two kinds of sex cells, or gametes (GAH-meetz), are involved. The male gamete, or sperm, and the female gamete, the egg or ovum, meet in the female's reproductive system. When sperm fertilizes (meets) an egg, this fertilized egg is called a zygote (ZYE-goat). The zygote goes through a process of becoming an ...
Mix together flour, semolina, sugar, salt, and yeast in a large mixing bowl. The Spruce / Christine Ma. Add warm water and mix to form a dough.

The aim of this study was to analyze possible effects of semen type (conventional vs. female sexed) and calf sex on fertility and production traits. For this purpose, field data of German Holstein heifers in Lower Saxony were evaluated. Sexed semen was mainly used for first insemination. 87.0% female calves were born from …
With semen, a healthy pH balance (anywhere between 7.2 and 8.0) corresponds to a more ammonia-like or chlorine-like smell. At the same time, organic chemicals called amines are largely responsible for the smell people associate with semen. The amines found in semen include putrescine, spermine, spermidine, and cadaverine.
