Background Fertilization is a key physiological process for the preservation of the species.
Consequently, different mechanisms affecting the sperm and the oocyte have been …

STUDY QUESTION Is the abundance of certain biochemical compounds in human cumulus
cells (CCs) related to oocyte quality? SUMMARY ANSWER Malonate, 5-oxyproline, and …

The objective of this study was to determine whether the cumulus oophorus cells
surrounding the human oocyte release a factor (s) that stimulates sperm velocity. Medium …

This study evaluated the differences in metabolites between cumulus cells (CCs) and mural
granulosa cells (MGCs) from human preovulatory follicles to understand the mechanism of …

Contents Fertilization encompasses a series of different steps which have to be performed in
a well‐orchestrated way to create a new individual. They include sperm capacitation, sperm …

Abstract β-Chemokine, regulated on activation and normally T-cell expressed and
presumably secreted (RANTES), is present in both the male and female genital tract fluids …

BACKGROUND Human spermatozoa appear to be guided by chemotaxis to the oocyte in
the female genital tract. While one of the sources of sperm chemoattractants is the cumulus …

In order to investigate whether the follicular tissue influences cumulus‐oocyte interaction
and, consequently, the fertilizability of the egg, four experiments were carried out. In the first …

One of the biggest prerequisites for pregnancy is the fertilization step, where a human
haploid spermatozoon interacts and penetrates one haploid oocyte in order to produce the …

The cumulus oophorus is a structure that surrounds the mammalian egg and plays a key
role in fertilization. However, very little is known with regards to how secretions from the …
