The physiology of follicle selection
During the follicular phase of the primate menstrual cycle, a single follicle usually matures to the preovulatory stage and releases its oocyte for fertilization and the potential establishment of pregnancy. In assisted reproductive technology procedures, it is desirable to override the natural process of follicle selection to produce many oocytes that are capable of being fertilized and underg...
متن کاملFollicle dynamics and selection in mares
The interovulatory intervals of mares contain various combinations of minor follicular waves (largest follicle does not become dominant) and major waves (largest follicle becomes dominant). After emergence of an ovulatory follicular wave, the follicles grow in a common-growth phase until the beginning of deviation. At deviation, the dominant follicle continues to grow and the subordinate follic...
متن کاملOvarian follicle selection and granulosa cell differentiation1
The reproductive strategy for avian species that produce a sequence (or clutch) of eggs is dependent upon the maintenance of a small cohort of viable, undifferentiated (prehierarchal) follicles. It is from this cohort that a single follicle is selected on an approximate daily basis to initiate rapid growth and final differentiation before ovulation. This review describes a working model in whic...

15 صفحه اولFollicle selection in cattle: follicle deviation and codominance within sequential waves.
Follicle deviation during bovine follicular waves is characterized by continued growth of a developing dominant follicle and reduction or cessation of growth of subordinate follicles. Characteristics of follicle deviation for waves with a single dominant follicle were compared between wave 1 (begins near ovulation; n = 15) and wave 2 (n = 15). Follicles were defined as F1 (largest), F2, and F3,...
