The aim of this study was to evaluate the effects of the reproductive status of female dromedary camels (pregnant vs. non-pregnant) on the chemical composition, hormonal profile and antioxidant capacity of follicular fluid collected from different sized ovarian follicles during the breeding season. One hundred ovaries were collected at slaughterhouse from fifty female dromedary camels. The ovar...

The primary function of the female ovary is the production of a mature and viable oocyte capable of fertilization and subsequent embryo development and implantation. At birth, the ovary contains a finite number of oocytes available for folliculogenesis. This finite number of available oocytes is termed "the ovarian reserve". The determination of ovarian reserve is important in the assessment an...

An important but poorly understood process in ovarian biology is the transition of the developmentally arrested primordial follicle to the developing primary follicle. Interactions between the epithelial and mesenchymal cells of the follicle are critical for the coordination of ovarian follicle development. The mesenchymal growth factor keratinocyte growth factor (KGF) (i.e., fibroblast growth ...

Mammalian females enter puberty with follicular reserves that exceed the number needed for ovulation during a single lifetime. Follicular depletion occurs throughout reproductive life and ends in menopause, or reproductive senescence, when the follicle pool is exhausted. The mechanisms regulating the production of a species-specific initial follicle pool are not well understood. However, the es...

Lagostomus maximus is a notable mammalian model for reproductive studies. Females have an extremely high ovulation rate, which is due to down-regulation of the follicular apoptosis pathway, which ensures a large pool of developing follicles. This large pool is supported by the convoluted anatomy of the mature ovary, whose germinal tissue is found in irregularly curved ridges throughout the cort...

Hirsutism is a common medical complaint among women of reproductive age, and it affects the majority of women with the polycystic ovary syndrome (PCOS). Increased rate of androgen production and its availability in tissue represent the main pathophysiological mechanisms responsible for hirsutism. In addition, androgens may be generated de novo in the hair follicle; therefore, circulating androg...

This manuscript reviews the present knowledge related to folliculogenesis in sheep.Folliculogenesis starts with formation of primordial follicles before birth, present as a pool containing a certain number of follicles. By the attainment of puberty, a group of follicles from that pool starts to grow, a process known as primordial follicle activation or recruitment. The number of growing primord...

Abstract Reproductive performance of heifers is a key indicator herd productivity. The objective was to evaluate markers and genes associated with reproductive tract characteristics through comparative approach. For this study, 295 admixed beef were examined via transrectal ultrasonography at approximately 13 months age. Exploratory factor analysis antral follicular count (count per size, side,...

Purpose: Considered as the most common hormonal disorder among women, polycystic ovary syndrome or PCOS affects 1 in 10 reproductive aged women (18 - 44 years). Ultrasonography is applied for assessing ovaries to detect PCOS. The patients affected by consist of 10-12 cysts present ovary, but more than are enough diagnose from ultrasound images. Then, examining presence follicles will be determi...

Sir, We thank Benaglia et al. (2009) for their interesting study. In contrast to Nakagawa et al. (2008), they found that spontaneous ovulation is impaired in ovaries affected by endometriotic cysts. The same group previously observed hypo-responsiveness of the affected ovaries to gonadotrophin-induced controlled ovarian hyperstimulation (COH) (Somigliana et al., 2006a, b). In all studies, ovula...
