After intercourse, sperm in the vagina passes through the cervix, the uterus, and then to the fallopian tubes. If a sperm encounters an ovum (egg), conception occurs. 4. Ovaries ➢ The female has two oval-shaped organs, called ovaries, that lie to the upper right and left of the uterus. ➢ The ovaries produce, store, and release eggs into the fallopian tubes during the process called ovulation. ➢ Each ovary measures about 1 1/2 to 2 inches in a grown woman. The ovaries are part of the endocrine system and produce estrogen and progesterone, female sex hormones. ➢ The ovaries are among the first organs to be formed as a female baby develops. By 20 weeks, the ovaries have about 6 to 7 million potential egg cells. From that point on however, the number begins to decrease rapidly. A newborn infant has between 1 million to 2 million egg cells. By puberty, the number of egg cells remaining is about 300,000. For every egg that matures and undergoes ovulation, roughly a thousand will fail. During the course of an average
