Dominant follicle growth patterns and associated endocrine dynamics in anovulatory and ovulatory waves in women. [PDF]

Reprod Fertil, 2023
Growth patterns and associated endocrine profiles were compared between dominant anovulatory (ADF) and ovulatory follicles (OvF) developing from different waves within and between menstrual cycles in women. Follicular mapping profiles of 49 healthy women

Follicular Size Threshold for Ovulation Reassessed. Insights from Multiple Ovulating Dairy Cows

Animals, 2022
In Bos. taurus cattle, follicular deviation to dominance begins when the selected ovulatory follicle reaches a mean diameter of 8.5 mm. The dominant follicle acquires the capacity to ovulate when it reaches a diameter of about 10 mm.

Effect of elevating luteinizing hormone action using low doses of human chorionic gonadotropin on double ovulation, follicle dynamics, and circulating follicle-stimulating hormone in lactating dairy cows

Journal of Dairy Science, 2022
: Double ovulation and twin pregnancy are undesirable traits in dairy cattle. Based on previous physiological observations, we tested the hypothesis that increased LH action [low-dose human chorionic gonadotropin (hCG)] before the expected time of ...

Understanding the Ovarian Interrelationship with Low Antral Follicle Counts (AFC) in the In Vivo Bos indicus Cow Model: Unilateral and Bilateral Main AFC as Possible Biomarkers of Ovarian Response to Hormonal Synchronisation

Biology, 2022
The antral follicle count (AFC) is a test in which the number of oocyte-containing follicles that are developing in both ovaries are visually counted. The count of these follicles strongly relates to the population of the growing follicle reserve on the ...

Controlled ovulation of the dominant follicle using progestin in minimal stimulation in poor responders. [PDF]

Reprod Biol Endocrinol, 2017
Background The use of progestin (P) during ovarian stimulation is effective in blocking the luteinizing hormone (LH) surge in women with normal ovarian reserve, however, its effects have not been determined in poor responders. This study aimed to explore

Uterine and systemic inflammation influences ovarian follicular function in postpartum dairy cows. [PDF]

PLoS ONE, 2017
The objective of this study was to determine the effects of uterine and systemic inflammatory responses to uterine bacterial contamination at calving in dairy cows on the growth and ovulatory outcomes of the first dominant follicle postpartum.

Prediction of Ovarian Follicular Dominance by MRI Phenotyping of Hormonally Induced Vascular Remodeling

Frontiers in Medicine, 2021
In the mammalian female, only a small subset of ovarian follicles, known as the dominant follicles (DFs), are selected for ovulation in each reproductive cycle, while the majority of the follicles and their resident oocytes are destined for elimination ...

QUANTITY AND QUALITY OF HARVESTED BUFFALO OOCYTES IN RELATION TO OVARIAN STRUCTURES AND METHODS OF COLLECTION [PDF]

Assiut Veterinary Medical Journal, 2005
A total number of 68 buffalo-cows ovaries were collected from slaughterhouse. In the first part of this study, 40 ovaries were classified according to the ovarian structures into: those with dominant follicle (DF, n = 14) , with corpus luteum  (CL, n=9 ),
