Childhood cancer treatments can cause female reproductive late effects. Radiation to the hypothalamic-pituitary-ovarian axis is associated with altered menarche, miscarriage, and implantation failure. Patients who receive chemotherapy and/or ovarian radiation are at risk of premature ovarian failure; the risk increases with increasing radiation dose, alkylating agent score, combination therapy,...
Long protocol of Gonadotropin-Releasing Hormone-analougue (GnRH-a) can result in the formation of ovarian cyst by the transient initial stimulatory effect which increases the levels of both follicle-stimulating hormone (FSH) and luteinizing hormone (LH). These cysts require surgical drainage or result in poor ovarian response. Ovarian cyst formation can be prevented by taking oral contraceptive...
Premature Ovarian Failure (POF) is associated with subfertility. Despite efforts to induce ovulation, success rates are low. We report a case of POF spontaneously conceiving twins while on hormone replacement therapy.
The actions of environmental toxicants and relevant mixtures in promoting the epigenetic transgenerational inheritance of ovarian disease was investigated with the use of a fungicide, a pesticide mixture, a plastic mixture, dioxin and a hydrocarbon mixture. After transient exposure of an F0 gestating female rat during embryonic gonadal sex determination, the F1 and F3 generation progeny adult o...
Polycyclic aromatic hydrocarbons (PAH) such as benzo[a]pyrene (BaP) are ubiquitous environmental pollutants found in tobacco smoke, air pollution, and grilled foods. Prenatal exposure to BaP causes premature reproductive senescence in mice, and other PAHs are transplacental ovarian carcinogens. Glutathione (GSH) is critical for detoxification of the reactive metabolites of PAHs. Therefore, we h...
The standard goal of all fertility treatments is the improvement of pregnancy rates in infertile patients. Within the last 20 years, ovulation induction has contributed to the success of assisted reproduction techniques e.g. in vitro fertilization (IVF) and embryo-transfer (ET). The efficacy of these techniques depends on a personalized protocol of controlled ovarian hyperstimulation (COH) and ...
Receiving the diagnosis of Primary Ovarian Insufficiency (POI) can be emotionally difficult and confusing for young girls and their families. Parents need assistance in knowing how to help their daughters understand and live with the diagnosis in a way that allows for healthy growth and development. This paper provides a starting point for parents and clinicians with "Tips and Tools for Talking...

BACKGROUND Ovarian failure is a common toxic effect of chemotherapy. Studies of the use of gonadotropin-releasing hormone (GnRH) agonists to protect ovarian function have shown mixed results and lack data on pregnancy outcomes. METHODS We randomly assigned 257 premenopausal women with operable hormone-receptor-negative breast cancer to receive standard chemotherapy with the GnRH agonist goser...
