Purpose: There is increasing evidence that the ovarian extracellular matrix (ECM) plays a critical role in follicle development. The rigidity of the cortical ECM limits expansion of the follicle and consequently oocyte maturation, maintaining the follicle in its quiescent state. Quiescent primordial, primary, and secondary follicles still exist in primary ovarian insufficiency (POI) patients, and techniques as in vitro activation (IVA) and drug-free IVA have recently been developed aiming to activate these follicles based on the Hippo signaling disruption that is essential in mechanotransduction.

The reduction in the quantity and quality of the oocytes with advanced age is physiological. However, some women experience DOR much earlier and become prematurely infertile, producing an accelerated follicular depletion towards primary ovarian insufficiency (POI).

Despite the existing limited results, it can be considered as a promising option for these patients to achieve their own offspring. Here we report the case of a 35-year-old woman diagnosed with POI at 30 years of age.

Further, an understanding of patterns in and between exposure metrics that are based on specific hazards of the storm can help in designing tropical cyclone epidemiological research.
Objectives: ) Provide an open-source data set for tropical cyclone exposure assessment for epidemiological research; and ) investigate patterns and agreement between county-level assessments of tropical cyclone exposure based on different storm hazards.
