Comprehensively understanding the female reproductive system is crucial for safeguarding fertility and preventing diseases concerning women's health. With the capacity to simulate the intricate physio- and patho-conditions, and provide diagnostic platforms, microfluidic chips have fundamentally transformed the k...

The production of two types of gametes, the sperm and the egg, does not necessarily imply the existenee of two distinet sexes; as a matter of fact, egg and sperm —two highly differe ntiated types of reproductive cells —may both be produced by the same individual. This occurs in ...

This is in contrast when compared in males where a diffuse production of estrogen meant that there are intricate estrogen-deficient productions and thus, less understood. It has been documented that estrogen plays a large role in spermatogenesis and in maintaining libido [28]. Estriol [E2] is a...
1d). Complementation of the iTgNPT1/Tomato parasite strain with a constitutively expressed copy of TgNPT1 (cTgNPT1) restored growth of the parasites in the presence of ATc (Fig. 1e), indicating that the growth phenotype observed in the mutant is solely the result of TgNPT1 knockdown. We...
In this study, we used an oral dose of 100 μg/kg bw/day of CD, a dose that has no effect on murine health34.We treated pregnant female mice from E6.5 to E15.5 with CD. We conducted the treatment during a reprograming window of E6.5 to E15.5, which is essential for normal de...

The mammalian oviduct is the venue of important events leading to the establishment of pregnancy. These events include final maturation and transport of the female and male gametes, fertilization, cleavage-stage embryonic development, and transport of the embryo to the uterus. In mammals, the physiol...
These surprising data indicate the “dual control” nature of the polytubey block by the fertilized egg cell and fertilized central cell. Importantly, two pollen tubes were targeted with higher percentages when both female gametes were unfertilized (∼80%, reported previously by Kasahara et al....
