The ovarian follicle luteinizing hormone (LH) signaling molecules that regulate oocyte
meiotic maturation have recently been identified. The LH signal reduces preovulatory follicle …

Ovarian Granulosa Cells (GCs) are known to proliferate in the developing follicle and
undergo several biochemical processes during folliculogenesis. They represent a …

Context The oocyte-secreted factors growth differentiation factor 9 (GDF9) and bone
morphogenetic protein 15 (BMP15) play essential roles in follicle development and oocyte …

The female reproductive system is of great significance to women's health. Aging of the
female reproductive system occurs approximately 10 years prior to the natural age …

Ovarian granulosa cells (GCs) are the most important source of estrogen. Therefore,
aromatase (estrogen synthase), which is the key enzyme in estrogen synthesis, is not only …

As an oocyte-specific growth factor, bone morphogenetic protein 15 (BMP15) plays a critical
role in controlling folliculogenesis. However, the mechanism of BMP15 action remains …

During folliculogenesis, the oocyte and surrounding cumulus cells form an ensemble called
the cumulus-oocyte complex (COC). Due to their interdependence, research on the COC …

Background Growth differentiation factor 9 (GDF9) and bone morphogenetic protein 15
(BMP15) genes play important roles in folliculogenesis. Altered expression of the two have …

The regulation of aromatase, an enzyme involved in the biosynthesis of estrogen in normal
and cancer cells, has been associated with growth factor signaling and immune response …

STUDY QUESTION Does the gonadotropin (GN) starting dose and the addition of
clomiphene citrate (CC) during the early follicular phase influence oocyte yield in poor …
