In this case, the population eventually consists of triploids only as long as selection against diploid apomicts is less than 1/3. However, if there is no selective disadvantage against either triploid, the population will have a higher frequency of the Aaa genotype than the AAa genotype (...

In addition, infertility may also occur even when the sexual function is normal, sometimes due to sperm abnormalities such as azoospermia and oligozoospermia. The pathogenesis of many male infertility-related diseases has been uncovered recently[9]. The female reproductive system consists of the ...

According to the species concerned, it is either the male gamete or the female gamete that accomplishes this result. In the mammals it is the sperm, of which two kinds are produced in equal numbers, one kind containing an X-chromosome (as do all the eggs), the other kind containing a ...
The aims of the present study were: (1) to evaluate the influence of sperm concentration (ranging from 0.5 × 106to 4 × 106spermatozoa/ml) and length of the gamete co-incubation time (2, 4, 6, 8, 10, 12, 16, 20, 24 or 28 h) onin vitrofertilization (IVF), assessing the sperm...
the mitochondria are therefore inherited maternally. ATP is provided by cells surrounding the oocytes. The male sperm cells, in contrast, are being produced continuously, with meiosis as a repair mechanism. The spermatocytes are motile in many eukaryotes, and their active mitochondria already suffer ...
The presence of spermatozoa or oocytes in the oviduct altered the secretion of specific proteins. Most of these proteins are known to have an influence on gamete maturation, viability, and function, and there is evidence to suggest these proteins may prepare the oviductal environment for arrival ...
. Furthermore, the combination of microfluidic chips and assisted reproductive technology (ART) is also a current research hotspot. The microfluidic technologies can be combined with various ART procedures to achieve embryo and gamete (sperm and oocyte) analysis, classification, operation, culture and ...
