Objective: Surgical removal of endometriomas, even if performed in experienced hands, leads to a decrease ovarian reserve varying degrees depending on age. This study was designed determine the pre- and post-surgical changes markers patients who underwent endometrioma cystectomy. Methods: Gözde Akademi Hospital gynecology outpatient clinic with diagnosis symptomatic included study. Fourteen nor...

Central 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. The DF was originally studied by looking ...

The number of antral follicles (a stage of folliculogenesis) determinates the quantity of oocytes potentially available for ovulation. It is one of the characteristics used to specify so called ovarian reserve which represents important factor to predict the result of IVF cycle, among other things. AFC can be set by usage of transvaginal ultrasonography (a sonography that applies an ultrasound ...

The adult mammalian ovary is devoid of definitive germline stem cells. As such, female reproductive senescence largely results from the depletion of a finite ovarian follicle pool that is produced during embryonic development. Remarkably, the crucial nature and regulation of follicle assembly and survival during embryogenesis is just coming into focus. This developmental pathway involves the co...

The ovarian follicle has a three-dimensional (3D) structure in which the oocyte is surrounded by tightly connected follicle cells that mediate the action of external signals and nourish the gamete during its maturation. Thus, the maintenance of follicle organization during the whole growth process is crucial for the correct acquisition of developmental competence. In recent years, much attentio...

Follicular growth over 2 mm in diameter is mainly regulated by gonadotrophins (FSH and LH). However, it is possible that between-follicle interactions may be involved in ensuring ovulation of a specific number of follicles. The present study tested specific hypotheses regarding: (1) a stimulatory role of atretic follicles on differentiation of follicles of the next wave; (2) a stimulatory role ...

BACKGROUND We recently reported poor inter-observer agreement in identifying and quantifying individual ultrasonographic features of polycystic ovaries. Our objective was to determine the effect of a training workshop on reducing inter-observer variation in the ultrasonographic evaluation of polycystic ovaries. METHODS Transvaginal ultrasound recordings from thirty women with polycystic ovary...

background: previous studies have reported the antifertility activities of sulfonamides. this study was designed to evaluate the effects of co-trimoxazole and its co-administration with folic acid on ovarian tissue in female rats. methods: a total of 54 rats were randomly divided into 9 groups (n=6) . group i served as the control and group ii (vehicle) received saline. other groups, iii to ix,...

A critical step in ovarian biology is the transition of the developmentally arrested primordial follicle to the growing primary follicle. The current study utilizes a rat ovarian organ culture system to investigate the role of insulin and insulin-like growth factor-1 (IGF-1) in this process. Four-day-old rat ovaries were cultured and the degree of primordial to primary follicle transition measu...

The effects of large follicle aspiration before and during superovulation on the ovarian response of beef cows were investigated using a crossover design. The removal of the largest follicle before superstimulation without assessment of functional dominance by serial examination of follicle development did not improve ovarian response. Similarly, the removal of large follicles on 1 day or 3 day...
