Fallopian Tubes

Ducts through which eggs travel to the uterus once released from the follicle, which is located in the ovarian follicle. Sperm normally meet the egg in the fallopian tube, the site at which fertilization usually occurs.

Fertility Specialist

A physician specializing in the practice of fertility. The American Board of Obstetrics and Gynecology certifies a subspecialty for OB-GYNs who receive extra training in reproductive endocrinology (the study of hormones) and infertility.

Fertility Treatment
Any method or procedure used to enhance fertility or increase the likelihood of pregnancy, such as Ovulation Induction (OI) treatment, varicocele repair (repair of varicose veins in the scrotal sac), controlled ovarian stimulation, and microsurgery to repair damaged fallopian tubes. The goal of fertility treatment is to help couples have a child.
Fertilization

The combining of the genetic material carried by sperm and egg to create an embryo. Normally occurs inside the fallopian tube (in vivo) but may also occur in a Petri dish (in vitro). (See also In Vitro Fertilization (IVF).)

Fibroid

Benign (not malignant or life-threatening) tumor of fibrous tissue that can occur in the uterine wall. Fibroids may be totally without symptoms or may cause abnormal menstrual patterns and infertility.

Fimbria

The finger-like extensions on the fallopian tubes that sweep the egg into the fallopian tube.

Follicle Stimulating Hormone (FSH)

A pituitary hormone that stimulates follicular development and spermatogenesis (sperm development). In a woman, FSH stimulates the growth of the ovarian follicle. In a man, FSH stimulates the Sertoli cells in the testicles and supports sperm production. Elevated FSH levels are associated with gonadal failure in both men and women.

Follicles

Fluid-filled sacs in the ovary, which contain the eggs released at ovulation. Each month an egg develops inside the ovary in a follicle.
