Variants of the thyroglobulin gene were significantly associated with premature ovarian failure in a Korean population. Three single nucleotide polymorphisms and one haplotype were found to be associated with a significant increase in the risk for premature ovarian failure.

Anti-Müllerian hormone (AMH) plays an important role in avian ovarian follicle development. The high mRNA expression of AMH in avian ovarian prehierarchical follicles helps prevent premature granulosa cell differentiation. Vitamin D3 was reported to downregulate AMH mRNA expression in granulosa cells of prehierarchical follicles in hens; however, the underlying molecular mechanism remains unknown.

Objectives: The pathogenesis of premature ovarian insufficiency (POI) not only affects the ovarian structure and function but also gives rise to complications such as osteoporosis and dyslipidemia. Although low-intensity pulsed ultrasound (LIPUS) has been proven effective in treating POI, its impact on the associated complications remains unexplored. Therefore, this study aims to investigate the effects of LIPUS irradiation on osteoporosis and dyslipidemia in a mouse model of POI.

Ovarian tissue cryopreservation and transplantation has emerged as a promising fertility preservation technique for individuals facing premature ovarian insufficiency due to various medical conditions or treatments. Xenotransplantation, involving the transplantation of ovarian tissue into animal hosts, has played a pivotal role in refining ovarian tissue cryopreservation and transplantation techniques and addressing key challenges. This review provides a comprehensive overview of the current landscape of ovarian tissue xenotransplantation research, focusing on its applications in investigating ovarian biology, optimizing ovarian tissue cryopreservation and transplantation protocols, and assessing safety concerns.

Ovarian function declines significantly as females enter middle-age, but the mechanisms underlying this decline remain unclear. Here, we utilize whole-organ imaging to observe a notable decrease in ovarian blood vessel (oBV) density and angiogenesis intensity of middle-aged mice. This leads to a diminished blood supply to the ovaries, resulting in inadequate development and maturation of ovarian follicles.
