It has been known that EGF-like factor secreted from LH-stimulated granuloma cells acts on granulosa cells and cumulus cells to induce ovulation process. Granulosa cells are changed the morphology with differentiating cell functions to produce proges

The absence of reliable markers to identify viable embryos for transfer at the early cleavage stage may contribute to the generally low implantation rates and high incidence of multiple births associated with IVF treatment. In the present study, we e

The motility of frozen-thawed sperm is very different among not only species but also among individuals within the same species. Since the optimal protocol needs to be adjusted for each species produce good quality frozen sperm, we investigated the p

The biosynthesis of androgens requires multiple steps and during the conversion of pregnenolone to 17α-hydroxypregnenolone and dehydroepiandrosterone (DHEA) by CYP17a1. Acetaldehyde is potentially formed as a by-product in theca cells during antral

Neat1 is a non-protein-coding RNA that serves as an architectural component of the nuclear bodies known as paraspeckles. Although cell-based studies indicate that Neat1 is a crucial regulator of gene expression, its physiological relevance remains un

Morphological changes are observed during the luteinization process of granulosa cells, however mechanisms and the roles are remained unclear. In the present study, we demonstrated that Sema3C is expressed in granulosa cells and then secreted to extr

Bacterial infections of the genital tract are one of the most serious causes of infertility in males. In some human patients with poor semen quality, leukocytospermia has been observed. Because leukocytes express the bacterial-lipopolysaccharide (LPS

Epidermal growth factor (EGF)-like factors [amphiregulin (AREG), betacellulin, and epiregulin] are induced by LH and activate the EGF receptor (ERBB1)/ERK1/2 pathway in granulosa cells and cumulus cells of preovulatory follicles to impact ovulation.

Gram negative bacteria are the predominant type detected in boar semen. Since these bacteria release lipopolysaccharide (LPS), and because polymyxin B (PMB) neutralizes LPS activity, the objective was to improve techniques for long-term storage of bo
