In addition, contractions in the muscular wall of the uterus are important in pushing out the fetus at the time of birth. During this phase, the following events occur: American Society of Reproductive Medicine. The labia majora enclose and protect the other external reproductive organs. Semen containing spermatozoa is ejaculated from the male at orgasm , into the vagina potentially enabling fertilization of the egg cell ovum to take place. Literally translated as "large lips," the labia majora are relatively large and fleshy, and are comparable to the scrotum in males.
The mons pubis and labia majora are covered with pubic hairs. The egg can then absorb the sperm and fertilization can then begin. As estrogen levels rise, like a switch, it turns off the production of follicle-stimulating hormone. The labia majora contain sweat and oil-secreting glands. These are narrow tubes that are attached to the upper part of the uterus and serve as tunnels for the ova egg cells to travel from the ovaries to the uterus. The fimbriae sweep the egg into the tube. The vagina functions as the receptacle for the penis during sexual intercourse and carries sperm to the uterus and fallopian tubes. Breasts and Mammary Glands The breasts are specialized organs of the female body that contain mammary glands, milk ducts, and adipose tissue. Each month during ovulation, a mature ovum is released. Fertilization Once the mature ovum is released from the ovary, the fimbriae catch the egg and direct it down the fallopian tube to the uterus. During the fetal period, the fetus grows larger and more complex until it is ready to be born. The ovum travels from the ovary to the fallopian tube, where it may be fertilized before reaching the uterus. During the follicular phase of the menstrual cycle, the following events occur: These organs are responsible for the production of the egg cells ova and the secretion of hormones. The speed of ovulation is periodic and impacts directly to the length of a menstrual cycle. The corpus luteum secretes the hormone progesterone. The clitoris is covered by a fold of skin , called the prepuce, which is similar to the foreskin at the end of the penis. Like the penis, the clitoris is very sensitive to stimulation and can become erect. The ovaries are small, oval-shaped glands that are located on either side of the uterus. The vast majority of the eggs within the ovaries steadily die, until they are depleted at menopause. Ovary The ovaries are small, paired organs located near the lateral walls of the pelvic cavity. Uterus The uterus or womb is the major female reproductive organ. The uterus is a pear-shaped muscular organ. If intercourse has taken place and a man's sperm has fertilized the egg a process called conception , the fertilized egg embryo will travel through the fallopian tube to implant in the uterus. Its major function is to accept a fertilized ovum which becomes implanted into the endometrium , and derives nourishment from blood vessels which develop exclusively for this purpose.
