heterogeneity of small EVs or the presence of nonvesicular extracellular matter (NV) pose …

The mechanism that causes the detachment of spermatozoa from the oviductal reservoir
around the time of ovulation remains to be elucidated. Because the cumulus cells of the …

Contents Fertilization and early embryo development relies on a complex interplay between
the Fallopian tube and the gametes before and after fertilization. Thereby the oviduct, as a …

Artificial insemination using diluted semen with reduced presence of seminal plasma has
been applied worldwide. Sperm stored in seminal plasma rather than diluted or removed …

Progesterone (P4) acts via the endometrium to promote conceptus growth and implantation
for pregnancy establishment. Many cells release extracellular vesicles (EVs) that are …
