Formation of mammalian oocytes and their growth, differentiation and maturation within ovarian follicles
Robert van den Hurk,Jia Zhao +1 more
TL;DR: This review highlights the factors that at present are known to be involved in the formation of mammalian oocytes and their growth, differentiation and maturation within ovarian follicles.
Journal ArticleDOI
Physiological classification of anovulatory conditions in cattle
TL;DR: Treatments that increase circulating progesterone concentrations can help in the treatment of these two conditions by potentially altering GnRH/LH pulses and allowing the final stages of follicular growth or resetting the hypothalamic responsiveness to the positive feedback effects of estradiol.
Journal ArticleDOI
Characteristics of ovarian follicle development in domestic animals.
TL;DR: Understanding the pattern of follicle development in different species is increasingly important for designing improved methods to manipulate reproduction in domestic animals.

TL;DR: Emerging data indicate that the main causes of variability are related to endocrine and ovarian factors, and so the number of studies and procedures addressing a better understanding and control of these factors may be increased in the future.
Journal ArticleDOI
Reproductive cycle of goats
TL;DR: Goats are spontaneously ovulating, polyoestrous animals as mentioned in this paper and the onset and length of the breeding season is dependent on various factors such as latitude, climate, breed, physiological stage, presence of the male, breeding system and specifically photoperiod.

Journal ArticleDOI
Regulation of ovarian follicular development in primates: facts and hypotheses.
TL;DR: A picture has emerged depicting the classic endocrine control of ovarian function by LH and FSH, entangled in a maze of regulatory systems hinging on cell-cell interactions between follicular cells, via action of a variety of molecules.

Ovarian follicular dynamics during the estrous cycle in heifers monitored by real-time ultrasonography.

TL;DR: It is shown that the development of ovarian follicles greater than or equal to 5 mm in heifers occurs in waves and that the most common pattern is three waves per estrous cycle.
Journal ArticleDOI
Temporal associations among ovarian events in cattle during oestrous cycles with two and three follicular waves.
TL;DR: The emergence of a 3rd wave was associated with a longer luteal phase, and the viable dominant follicle present at the time of luteolysis became the ovulatory follicle.

Selection of the dominant follicle in cattle
Journal ArticleDOI
Pattern of growth of dominant follicles during the oestrous cycle of heifers.
TL;DR: The analysis of the rates of growth and atresia suggest that the rate of growth is slowest during mid-cycle, and the number of dominant follicles that developed in the ovary ipsilateral to the corpus luteum was greater than in the contralateral ovary.
