Expression of the gonadotropin receptors during follicular development
Background Gonadotropins induce follicular development that leads to ovulation and luteinization. In women, the level of gonadotropins, along with the expression of their receptors, changes dynamically throughout the menstrual cycle. This study aimed to clarify the mechanisms underlying these phenomena. Methods The literature was reviewed, including that published by the authors. Main findi...
متن کاملOvarian follicular development during the estrous cycle in gilts following electrocautery of fillicles.
This experiment was designed .to study follicular development at various days of the estrous cycle in intact gilts for comparison with follicular growth following the removal of surface follicles from the ovaries by electrocautery at different stages of the estrous cycle. Thirty-five Yorkshire-Poland China gilts were divided equally into seven subgroups. Four of the subgroups served as controls...
متن کاملHormonal Profile of Ovarian Follicular Fluid and Blood Plasma during Different Stages of Estrous Cycle in Holstein Cattle
The aim of this study was to evaluate the concentrations of reproductive hormones in blood plasma and in follicular fluids of different sized follicles during various stages of the estrous cycle in Holstein cattle. Jugular blood samples from 42 adult Holstein cattle were collected immediately after the slaughter. Antral fluids from small (4-5 mm), medium (6-9 mm) and large (10-20 mm) follicles ...
متن کاملOvarian follicular dynamics during estrous cycle and its aberrations during certain reproductive disorders in buffalo
Ovarian follicular development in the species follows a wave dynamics involving mostly 2wave or 3-wave cycles. Although there are still large gaps in our understanding of the etiopathogenic mechanisms underlying reproductive disorders in buffalo, available literature suggests alterations in ovarian dynamics at one or more stages of follicular development. This article gives a brief account of t...
متن کاملOvarian Follicular Dynamics during the Estrous Cycle in Jennies in Upper Egypt
The objective of the current study was to describe follicular dynamics in Egyptian Jennies throughout the estrous cycle. In this experiment, 8 estrus cycles in 8 cyclic Jennies were studied from February to June using ultrasonography. The result revealed that one follicular wave per cycle was recorded throughout the studied period. Dominant follicle (DF) was firstly detected at -0.80 ± 0.84 day...
