Aim: The present study was designed to investigate the therapeutic role of Curcumin against fluoride induced toxicity on adrenal gland of rats by using scanning electron microscopy (SEM). Methodology: Wistar albino rats were divided randomly into six groups The group I was administered with 1 ml of deionized water/kg b.w./day orally for 40 days. The Groups II and III were given 300 and 600 mg of NaF/kg b.w./day for the same period, respectively. The group IV was given 200 mg/kg b.w. of Curcumin for 20 days. The Groups V and VI were treated with 300 and 600 mg of NaF/kg b.w./day for 40 days respectively were post-treated with 200 mg of Curcumin for next 20 days. The animals were excised and adrenal tissue was taken out and processed for SEM. Results: The results revealed that rats exposed to 300 mg/kg b.w./day of NaF showed rough edges, numerous microvilli and damaged surface with crystal depositions. Also, numerous granules were distributed all over the surface. The rats treated with 600 mg/kg b.w./day of NaF showed decellularized adrenal tissue along with network of collagen fibres. Moreover, adrenal gland surface displayed abrasions and distorted cuboidal cells. The filopodia were prominent on the surface and wall of cavity possessed rough outline. After post-treatment with Curcumin, fluoridated adrenal gland of rats showed normal structure, reappearance of cuboidal cells on the surface as well as less number of microvilli and filopodia. Conclusion: The post-treatment with Curcumin possess therapeutic potential against NaF induced toxicity in adrenal gland of rats.

In the present era, infertility is one of the major issues which restricts many couples to have their own children. Infertility is the inability to achieve a clinical pregnancy after regular unprotected sexual intercourse for the period of one year or more. Various factors including defective male or female germ cell development, unhealthy and improper lifestyles, diseases like cancer and associated chemo-or-radiation therapies, congenital disorders, etc., may be responsible for infertility. Therefore, it is highly important to understand the basic concepts of germ cell development including primordial germ cell (PGC) formation, specification, migration, entry to genital ridges and their molecular mechanisms, activated pathways, paracrine and autocrine signaling, along with possible alteration which can hamper germ cell development and can cause adversities like cancer progression and infertility. Knowing all these aspects in a proper way can be very much helpful in improving our understanding about gametogenesis and finding possible ways to cure related disorders. Here in this review, various aspects of gametogenesis especially female gametes and relevant factors causing functional impairment have been thoroughly discussed.
