Chocolate cysts from ovarian follicles
Fertility and Sterility, 1999To study the development of chocolate cysts by serial transvaginal ultrasonographic tracking of ovarian follicles.Retrospective study.Department of Obstetrics and Gynaecology, Sunderland Royal Hospital, Sunderland, United Kingdom.We reviewed case notes of all patients who underwent laparoscopy for diathermy to endometriosis/ovarian diathermy/aspiration

Follicle culture after ovarian cryostorage
Maturitas, 1998Cryostorage of ovarian cortical tissue, before devastating chemo- and/or radiotherapy for cancer, permits survival of primordial and early preantral follicles. This work aims for a system allowing the long-term maturation in vitro (IVM) of small immature oocytes up to fertilisable metaphase II oocytes.A culture system allowing follicle attachment ...

Can ovarian follicles fossilize?
Nature, 2013ARISING FROM X. Zheng et al. , 507–511(2013)10.1038/nature11985 In a recent report Zheng et al. describe ovarian follicles in three fossil birds from the Early Cretaceous period of China belonging to Jeholornis and two enantiornithine species1.

Reconstituting the ovarian follicle
Science, 2021Developmental Biology Recent advances have enabled the generation of oocytes from pluripotent stem cells in vitro. However, these cells require a somatic environment to develop fully as reproductive cells. Yoshino et al. applied what is known about differentiation processes in vivo to determine a culture condition to differentiate embryonic stem cells ...

The bovine dominant ovarian follicle
Journal of Animal Science, 2007Central roles in reproductive biology (i.e., growth and development of the oocyte, steroidogenesis, and ovulation) are played by the ovarian dominant follicle (DF). The DF is different from other follicles because it can escape atresia (the fate of all other follicles), and if exposed to the LH surge, its cells will differentiate into the corpus luteum.

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.

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.

Follicle dynamics during ovarian ageing
Molecular and Cellular Endocrinology, 2000The human ovary is endowed at birth with a fixed number of primordial follicles which steadily declines throughout life as a result of atresia and recruitment towards ovulation. The pattern of this decline is not exponential, but more bi-exponential corresponding to a 'broken-stick' regression of logged total numbers of follicles against age.

Orexin system in swine ovarian follicles
Domestic Animal Endocrinology, 2018Successful reproduction is strictly linked to metabolic cues. The orexins are a family of hypothalamic neurohormones, well known for their key role in the control of food intake and the involvement in several aspects of the reproductive process. The biological actions of both orexins are carried out through binding to the related Orexin 1 (OX1R) and ...
