Members of the transforming growth factor-β (TGF-β) superfamily have wide-ranging
influences on many tissue and organ systems including the ovary. Two recently discovered …

In this study, two experiments were performed, the first of which examined the ovarian
response in ewes that were subject to unilateral ovariectomy (ULO) at different intervals (0 …

Given the paucity of information on the potential roles of bone morphogenetic proteins
(BMPs) in the ruminant ovary we conducted immunolocalization and functional studies on …

In humans and domestic mammals, pivotal processes in ovary development, including
primordial follicle assembly, occur prenatally. These events are essential for determining …

The mechanisms whereby the high variation in numbers of morphologically healthy oocytes
and follicles in ovaries (ovarian reserve) may have an impact onovarian function, oocyte …

The aim was to investigate potential interactions between FSH and intraovarian growth
factors in modulating secretion of inhibin A (inh A), activin A (act A), follistatin (FS), estradiol …

Background The intracellular signalling mechanisms that regulate ovarian follicle
development are unclear; however, we have recently shown differences in the Akt and Erk …

We reported previously that bone morphogenetic proteins (BMPs) potently suppress CYP17
expression and androgen production by bovine theca interna cells (TC) in vitro. In this study …

To study the effect of re-immunization against inhibin on ovarian response and hormonal
profiles, Japanese beef heifers (n= 5) were re-immunized three times with inhibin vaccine …

Intrafollicular concentrations of inhibin A and estradiol vary inversely during development of
dominant follicles in cattle. Thus, we hypothesized that inhibin has a negative autocrine or …
