The use of triptolide (TP) is limited by its poor water solubility and severe toxicity. In this study, we developed an active drug delivery system (TP-loaded nanoparticles) that could help improve the water solubility of TP and decrease its toxicity. Then, we investigated whether TP-loaded nanoparticles could be used to establish a novel premature ovarian insufficiency mouse model. The mice treated with TP-loaded nanoparticles for 35 days displayed normal growth, decreased serum antimullerian hormone, prominent ovarian fibrosis and vacuolar changes, fewer follicles and corpus lutea, increased collapsed oocytes and follicle apoptosis, and sterility. In conclusion, this model appears to show the reproductive characteristics associated with premature ovarian insufficiency in women and will allow us to study the mechanism of the effects of traditional Chinese medicine on gonadal toxicity.

Abnormality of granulosa cells (GCs) is the critical cause of follicular atresia in premature ovarian failure (POF). RIPK3 is highly expressed in GCs derived from atretic follicles. We focus on uncovering how RIPK3 contributes to ovarian GC senescence.

Radiotherapy is a critical treatment for cancer but poses significant risks to ovarian tissue, particularly in young females, leading to premature ovarian failure (POF). This study examines the therapeutic potential of etoricoxib nanostructured lipid carriers (ETO-NLC) in mitigating radiation-induced ovarian damage in female rats. Twenty-four female rats were randomly assigned to four groups: a control group receiving normal saline, a group exposed to a single dose of whole-body gamma radiation (6 Gy), a group treated with etoricoxib (10 mg/kg) post-radiation, and a group treated with ETO-NLC for 14 days following radiation.

Oxidative stress (OS) is established as a key factor in the etiology of both male and female infertility, arising from an imbalance between reactive oxygen species (ROS) production and the endogenous antioxidant (AOX) defenses. In men, OS adversely affects sperm function by inducing DNA damage, reducing motility, significantly impairing sperm vitality through plasma membrane peroxidation and loss of membrane integrity, and ultimately compromising overall sperm quality. In women, OS is implicated in various reproductive disorders, including polycystic ovary syndrome, endometriosis, and premature ovarian failure, leading to diminished oocyte quality, disrupted folliculogenesis, and poorer reproductive outcomes.

Introduction: Infertility is a very discussed problem in many endocrinological and gynecological courses and congresses. In a rapidly revolving environment women tend to postpone pregnancy to have security in their financial life and career.We discuss primary and secondary infertility and the hormonal results in women that presented for a desire to conceive with their partner.

REV7, also known as MAD2B, MAD2L2, and FANCV, is a HORMA-domain family protein crucial to multiple genome stability pathways. REV7's canonical role is as a member of polymerase ζ, a specialized translesion synthesis polymerase essential for DNA damage tolerance. REV7 also ensures accurate cell cycle progression and prevents premature mitotic progression by sequestering an anaphase-promoting complex/cyclosome activator.
