Female Reproductive System n Fallopian Tubes n n n Tubes that connect the uterus to both ovaries. Fertilization (union of sperm and ova) occurs in these tubes Ovaries n n Female sex glands that mature ovum and produce estrogen & progesterone Secondary Sex Characteristics n n Breast development Underarm and pubic hair Widened hips & increase in body fat Start of menstrual cycle
