Family Life 421 Ms. MacLean By the end of this unit, you will be able to: discuss and describe the organs of the male and female reproductive system; identify the different parts of the male and female reproductive system on a diagram; discuss certain male and female health concerns related to the reproductive system. Female Reproduction System The female reproductive system’s primary function is for reproduction. An egg cell (ovum) is produced which, when united with a sperm cell, will eventually form a baby. Although the female has external and internal reproductive organs, the organs of the system are primarily internal. The external organs are called the vulva. The vulva consists of the: Clitoris Mons pubis Labia majora (Outer lips) Labia minora (Inner lips) Vaginal opening The clitoris is a knob of tissue, located in front of the vaginal opening. The clitoris has no reproductive function, but is important in producing sexual arousal. The mons pubis is a rounded, fatty pad of tissue, covered with pubic hair. The mons pubis is located on top of the pubic bone. The labia majora (outer lips) is the outer fold of tissue on either side of the vaginal opening. The labia minora (inner lips) is the inner folds of skin which are inside the labia majora. The labia minora form a hood over the clitoris. The functions of the labia are: To protect against germs entering the body For sexual arousal The vaginal opening is visible with the labia are parted. Vaginal Opening The internal organs are the: Vagina Uterus Fallopian tubes Ovaries The vagina is a tubelike passageway, about 4 to 5 inches long. It is also called the birth canal; it stretches to allow for the birth of a baby. The vagina leads to the cervix (the neck of the uterus). The cervical opening is very small, but during child birth it opens (dilate) for the baby. The hymen is a thin membrane, located just inside the vaginal opening. The hymen has no particular function and is not present in all females. There are many myths related to the hymen, but many are not true. Some women may feel discomfort with the breaking of their hymen. The uterus is a strong, elastic muscle, about the size of a fist. The primary function of the uterus is to hold and nourish a fetus (developing baby). On each side of the uterus are the Fallopian tubes. Fertilization of the ovum (the joining of a sperm cell and egg cell) occurs in the Fallopian tubes. The ovaries are the female sex glands on both sides of the uterus. The function of the ovaries are: Production of female sex hormones (estrogen and progesterone) House the egg cell (ovum) Ovulation is the process of an ovary releasing a mature egg cell (ovum) into that ovary’s Fallopian tube. A ovum can live for about two days in the Fallopian tube. If sperm are present, one sperm will enter the ovum. This is call fertilization. Pregnancy begins at this point. If the ovum is fertilized, it moves into the uterus and attaches to the lining. The ovum will develop into a baby while in the uterus. If the ovum is not fertilized, it dies and passes into the uterus. The uterine lining is not needed because there is no pregnancy, so the uterine muscles begin to contract and the lining of the uterus is shed. This lining passes through the vagina and out of the body during a process called mestruation. Menstruation (also called a period) usually takes 4 to 7 days, but can be shorter or longer. Each female’s menstrual period is different. During menstruation, the female loses between 2 and 3 tablespoons of blood in additional to the uterine lining (tissue). Almost all females being menstruating between the ages of 10 and 15. Hormones control the menstrual cycle so each female’s cycle is unique to her. Menstruation Cycle Because the uterus contracts to break down the lining, the female may experience cramps. Light exercise, a warm bath, or a heating pad will relax the muscles to assist with the cramps. Severe cramps require medical attention. Bathing of the vaginal area is important, but becomes even more important during menstruation. Sanitary napkins or tampons must be used to catch the menstrual flow, and must be changed every 3 to 4 hours. Tampons left in for more than 4 hours increases the risk of infection. Women have certain reproductive health issues: Premenstrual Syndrome (PMS) Sterility Breast Cancer Premenstrual Syndrome (PMS) refers to a variety of symptoms females experience during menstruation, including: Nervous tension Anxiety Irritability Bloating Weight gain Depression Mood swings Fatigue The causes of PMS are not fully understood, but may be related to hormones or nutritional deficiency. Most doctors recommend diet and life-style changes. PMS sufferers must try to reduce stress, and reduce their intake of sugar, salt, caffeine, nicotine, and alcohol. How to Relieve PMS Symptoms Women can become sterile through: A blockage in one of both of the Fallopian tubes The inability to ovulate Endometriosis, a condition in which uterine tissue grows outside the uterus, in the pelvic cavity. Breast cancer is the second leading cause of death of women after lung cancer (US). Breast cancer is not preventable, but it is treatable and curable. Females with a family history of breast cancer are twice as likely to develop this cancer. Women should complete monthly self-breast examinations. Symptoms of breast cancer (in women and men) are: Change in breast or nipple appearance Lump or swelling in the breast Lump under the armpit
