1Male and Female Reproductive System CMT Review The Reproductive SystemMale and Female Reproductive System
2Male Reproductive System Function:Produces and delivers spermto the female reproductive system
3Production and Passage of Sperm: Testes:A pair of organs that make sperm and testosterone.Testosterone is the main male sex hormone. It helps regulate production of sperm and development of male characteristics.Epididymus:Stores sperm
4Vas Deferens:Tube that goes from the epididymus into the body through the prostate gland. Sperm moving through the vas deferens mixes with fluids from several glands. This mixture is called semen.Urethra:From vas deferens semen passes into the urethra, a tube that runs through the penis. The penis is the external organ that transfers semen into the female body.
5Female Reproductive System Function:Produces eggs,NurturesFertilized eggs(zygotes), givesbirth
6Production and Fertilization of Eggs: Ovaries:2 organs that make eggs. They also release estrogen and progesterone, main female sex hormones. These hormones regulate release of eggs and development of female characteristics.Fallopian Tubes:During ovulation, an egg is released form an ovary and passes into the fallopian tube (leads from an ovary to the uterus). This is where fertilization occurs.
7Uterus:If the egg is fertilized, a zygote enters the uterus. The zygote may embed in the thick lining of the uterus (organ in which the zygote develops into a baby).Vagina:When baby is born, s/he passes from the uterus through the vagina and out of the body.
8Menstrual Cycle: What it is: From puberty to ~early 50s, a woman’s reproductive system goes through monthly changes. These changes (menstrual cycle) prepare the body for pregnancy.
91st day of menstruation: This is counted as the 1st day of the cycle.Discharge of blood and tissue from the uterus starts and continues for about 5 days.When menstruation ends:The lining of the uterus thickens.Ovulation:The release of an egg from the ovary.This happens around the 14th day of the cycle.
10If the egg is not fertilized: Menstruation will begin and the egg will be flushed away out of the body.How long the cycle takes:The whole cycle takes about 28 days.If the egg is fertilized:The fertilized egg (zygote) moves down into the uterus where it will grow for the next 9 months before being born. The menstrual cycle usually stops at this time.
11Diseases: STDs: Sexually Transmitted Diseases. Ex: Chlamydia, herpes, hepatitis B, etc…STDs pass from person to person during sexual contact.
12Diseases: Cancer: Disease in which cells grow at an uncontrolled rate. Cancer cells start out as normal cells and then some trigger makes them multiply uncontrollably.Men: most common is cancer of the testes and cancer of the prostate gland.Women: most common are breast cancer and cancer of the cervix.
13Diseases: Infertility: Cannot have children. Men: if they don’t produce enough sperm.Women: if they don’t ovulate normally.STDs: (ex: gonorrhea and chlamydia) can lead to infertility in women. This can occur in men, but not as common as women.
