REGULATION OF OVARIAN FOLLICLE ATRESIA
Annual Review of Physiology, 1997▪ Abstract The majority of ovarian follicles undergo atresia, a hormonally controlled apoptotic process. Monitoring apoptotic DNA fragmentation provides a quantitative and sensitive endpoint to study the hormonal regulation of atresia in ovarian follicles.

Bioengineering and the Ovarian Follicle
2007Three-dimensional scaffolds are widely used in the field of tissue engineering, which combines the principles and methods of the life sciences with those of engineering to provide a fundamental understanding of structure–function relationships in normal and diseased tissues, to develop materials and methods to repair damaged or diseased tissues, and to

The ovarian follicle and fertility
The Journal of Steroid Biochemistry and Molecular Biology, 1991The precise roles of follicle stimulating hormone (FSH) and luteinizing hormone (LH) in the control of preovulatory follicle growth has been re-examined. Suppression of both pulsatile LH secretion and FSH or specific suppression of FSH results in an inhibition of preovulatory follicle growth beyond 2.5 mm dia.

Extracellular matrix in ovarian follicles
Molecular and Cellular Endocrinology, 2000A lot is known about the control of the development of ovarian follicles by growth factors and hormones, but less is known about the roles of extracellular matrix in the control of follicular growth and development. In this review we focus on the specialized extracellular matrix of the basal laminas that are present in ovarian follicles.

Predictors of ovarian follicle number
Fertility and Sterility, 2000To identify factors associated with ovarian follicle density in women of reproductive age.Women undergoing incidental oophorectomy responded to structured interviews. Grossly normal ovaries were sectioned and assessed for follicle density.University hospital.102 women undergoing hysterectomy with incidental oophorectomy who had morphologically normal ...

Effects of melatonin on ovarian follicles
European Journal of Obstetrics & Gynecology and Reproductive Biology, 2013To evaluate the histomorphometry and expression of Ki-67 and c-kit in ovarian follicles of pinealectomized or melatonin-treated pinealectomized rats.Forty adult rats were randomly divided into four groups of 10 animals: Group I - control; Group II - sham-pinealectomized; Group III - pinealectomized (Px), and Group IV - Px treated with melatonin (10μg ...

Ovarian control of follicle development
American Journal of Obstetrics and Gynecology, 1995A variety of ovarian autocrine and paracrine factors may modulate folliculogenesis and steroid production. The developmental program that leads to the production of a dominant follicle involves a precise quantitative and temporal pattern of expression of a large number of genes.

In Vitro Development of Ovarian Follicles
Seminars in Reproductive Medicine, 2011Tissue banking of ovarian material is being increasingly offered to a variety of patients as a means of fertility preservation. This tissue comprises thin cortical surface biopsies that contain predominantly primordial follicles, and currently the only option to restore fertility is by transplantation.

The Reproductive Lifespan of Ovarian Follicle
Reproductive SciencesThe functional unit within mammalian ovaries is the ovarian follicle. The development of the ovarian follicle is a lengthy process beginning from the time of embryogenesis, passing through multiple different stages of maturation. The purpose of this review is to describe the most basic events in the journey of ovarian follicle development, discussing ...

Hemorrhagic ovarian follicles in llamas
Theriogenology, 1991The ovaries of 74 llamas were examined daily by transrectal ultrasonography for at least 30 d. Hemorrhagic follicles were observed in 13 (18%) llamas (incidence per anovulatory dominant follicle, 16%). The proportion of llamas in which a hemorrhagic follicle was detected was different among groups (nonmated, 8/25; mated to a vasectomized male, 4/21 ...
