Follicular dynamics and ovarian steroid secretion in sheep during anoestrus

Ovarian follicular dynamics during anoestrus in Anglo-Nubian and Saanen goats raised in tropical climate. Tropical Animal

Fertility of sheep given antisera to steroids during anoestrus.

The incidence of oestrus (6/46) and ovulation (14/46) in ewes given antisera to androstenedione, oestrone, oestradiol and testosterone either separately or as a mixture of these sera at the time of treatment with progestagen sponges alone or progestagen sponges followed by LH-RH was similar to that of control ewes (2/13 and 6/13 respectively). The number of corpora lutea (CL) recorded for those...

Steroid Production and Follicular Development of Neonatal Mouse Ovary during In Vitro Culture

Ovarian follicular dynamics in lines of sheep (Finn, Merinos) selected on ovulation rate.

Ewes from selected lines of sheep from each of two breeds, Finns (high ovulation rate, low ovulation rate and control lines with respective ovulation rates of 5.4, 2.7 and 3.3) and Merinos (T Merinos selected for increased ovulation rate and control Merinos with respective ovulation rates of 1.9 and 1.2) were used to examine how selection to alter ovulation rate had altered follicle development...

Ovarian 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...
