background: poor ovarian response phenomenon has been observed in some of the in vitro fertilization-embryo transfer patients. some investigations found that follicle stimulating hormone receptor (fshr) gene plays a role in the process, but no direct evidence shows the correlation between genotypes of fshr and ovarian response. objective: exploring the molecular mechanism behind the mutation of...

objective(s): pesticides has wide range of infertility in female reproductive. this study was done to evaluate the effect of movento pesticide on development of granulosa cells and ovarian follicles and foxo1 and vnn1 gene expression in balb/c mice. materials and methods: in this study 40 healthy balb/c mice 5-6 weeks age were used. animals were randomly allocated into four groups. control (wit...

The purpose of this study was to determine the role Oxidized Low Density Lipoprotein (OX LDL) promotes insufficient autophagy and apoptosis ovarian granulosa cells through regulation Reactive Oxygen Species (ROS) mediated PI3K Akt/mTOR pathway.

Premature ovarian failure (POF), an ovarian disorder of multifactorial origin, is defined as the occurrence of amenorrhea, hypergonadotropism and hypoestrogenism in females <40 years old. Apoptosis of ovarian granulosa cells is important in POF and understanding the regulatory mechanism underlying ovarian granulosa cell apoptosis may be beneficial for the management of POF. Increasing evidence ...

Background: Diminished ovarian reserve (DOR) is a primary infertility disorder characterized by a reduction in the number and/or quality of oocytes, usually accompanied by high follicle-stimulating hormone (FSH) levels and regular menses. DOR aetiology factors are different, such as genetic factors, ageing, autoimmune disorders, adrenal gland impairment factors and iatrogenic causes, e.g. chemo...

The general objective of this in vitro study was to examine the secretory activity of ovarian granulosa cells of hens after lead (Pb) and molybdenum (Mo) administrations. In this study the effect of various doses of Pb and Mo on the insulin-like growth factor-I (IGF-I) and progesterone (P ) release by ovarian granulosa 4 cells was demonstrated. Ovarian granulosa cells were incubated with lead a...

Background: To study the morphological development and histomorphometry of foetal and adult ovaries in Kano brown goats. Materials and Methods: Fifty-one foetal and fourteen adult ovaries obtained from slaughtered Kano brown does in Nsukka abattoir were used for this study. The ages of the adult does were determined by dentition and foetuses by crown rump length method. The foetal and adult ova...
