Much less attention has been paid to the events that occur between gamete fusion and first embryonic cleavage. The interaction of the mammalian spermatozoa with the oocyte during and after gamete fusion is a complex and meticulously orchestrat

https://doi.org/10.1057/9780230288850, spermatogenesis proceeds for the reproductive lifetime of the animals. The continuation of this process depends on a pool of spermatogonial stem cells within the testes that undergo asymmetric division to both maintain the stem cell population and give rise to progenitors that will proceed through

This exocytotic event is mandatory for fertilization because it enables passage of the sperm through the ZP and its subsequent fusion with the egg oolema. Many artificial stimuli are reported to trigger the AR, ei
