A woman is born with all of the eggs she will ever have so as she ages, she has fewer eggs and the percentage of genetically normal eggs declines.

30-50% of individuals presenting with infertility have endometriosis.

Hyperprolactinemia causes infertility in around 11% of oligospermic males. Hyperprolactinemia also directly influences spermatogenesis and steroidogenesis by acting on prolactin receptors present in Sertoli cells and Leydig cells in testes, and produces primary hypogonadism and infertility.

Prolactin is a hormone that plays a role in fertility by inhibiting follicle stimulating hormone (FSH) and gonadotropin-releasing hormone (GnRH), the hormones that trigger ovulation and allow eggs to develop and mature.

Vaginal Contraceptive Ring thickens the cervical mucus. It also releases two hormones (progestin and estrogen) to stop the ovaries from releasing eggs.
