Hormonal Imbalance Fertility Causes

Hormonal imbalances disrupt ovulation, egg quality, and uterine lining, making conception difficult. Common causes include Polycystic Ovary Syndrome (PCOS), thyroid disorders (hypo/hyperthyroidism), hyperprolactinemia (high milk-producing hormone), Primary Ovarian Insufficiency (POI), and lifestyle factors like high stress (cortisol) or extreme weight fluctuations. Indira IVF +2 Key Hormonal Causes of Infertility Polycystic Ovary Syndrome (PCOS): The leading cause of female infertility. Elevated androgens (male hormones) prevent regular egg release and cause irregular periods. Cleveland Clinic +3 Thyroid Dysfunction: Both underactive and overactive thyroids interfere with metabolism and reproductive hormones, preventing normal egg maturation and increasing miscarriage risk. Orchid Fertility Clinic +1 Hyperprolactinemia: Excess prolactin in the blood disrupts the brain's regulation of Follicle-Stimulating Hormone (FSH) and Luteinizing Hormone (LH), preventing ovulation. Orchid Fertility Clinic +1 Luteal Phase Defect: The ovary fails to produce enough progesterone after ovulation. This results in an inadequately prepared uterine lining, making embryo implantation difficult.
