1. What is the menstrual cycle? What role does it play in allowing a baby to be conceived? The menstrual cycle is also known as having periods. It is part of the female’s reproductive cycle that starts when a girl becomes sexually mature at the time of puberty. During a menstrual period a woman bleeds from her uterus via the vagina. This can last anything from three to seven days and each period starts approximately every 28 days if the woman doesn’t get pregnant during a given cycle. The role that the menstrual cycle plays in allowing a baby to be conceived is it provides with all that is necessary for the baby to grow, eg. temperature
2. Describe the process of ovulation. Ovulation is controlled by the hypothalamus of the brain. Ovulation is the process in a female’s menstrual cycle when a mature ovarian follicle ruptures and discharges an egg. Ovulation can also occur in the estrous cycle of other female mammals, which changes in many fundamental ways from the menstrual cycle.
3.What is the purpose of lining the uterus? During menstruation or the estrous cycle, the lining of the uterus grows into a thick layer of glandular tissue. During pregnancy, the glands and blood vessels in the endometrium increase in size and number, increasing oxygen and nutrition to the embryo and fetus.
4. What is the role of the ovary? The ovaries are the main part of the normal development and reproductive function of women. They are a pair of glands in the female reproductive system where eggs are kept and estrogen is manufactured. The function is to release egg cells and to produce hormones. The normal ovary produces two very important hormones. For the first half of the menstrual cycle only estrogen is produced but in the later half the ovary also starts to produce another hormone, progesterone.
5. Can you get pregnant from a swimming pool, spa, toilet or from swallowing semen? Research these urban legends and find the truth for each.
You cannot get pregnant from a swimming pool because the chemicals and heat of the water would kill the sperm. You cannot get pregnant from swallowing semen, because there is no way for the sperm to get through the stomach to the uterus. It is possible to get pregnant anywhere if you are having sex, but from all of these myths it would be very difficult to become pregnant.
6. How long can sperm survive once ejaculated? What are the optimal conditions for them to survive? Sperm in the vagina, can only survive for up to six hours due to the acidic vaginal conditions. Sperm exposed to air usually die within minutes of ejaculation. A sperm sample collected in a container and kept at body temperature may remain alive for several hours, but the sperms' fertilizing capability drops dramatically within 60 minutes after ejaculation. However sperm that move from the vagina into the uterus can survive much longer. Studies have shown that conception is possible up to five to six days after intercourse
7. What are the most effective sexual positions to get pregnant?
The most effective sexual position to become pregnant is with the male on top, because of the law of gravity will help the sperm flow to the uterus quicker.
8. Identify 3 different types of birth control, their success rate and describe how they work. CONDOM:
a condom has a 93-95% success rate at preventing women from becoming pregnant. A condom prevents semen from getting into a woman’s vagina. IMPLANON: an implanon is a stick that is inserted into your arm and lasts for 3 years. The implanon releases a hormone called progestin that stops ovaries from releasing eggs. An implanon has a 99.99% success rate. EMERGANCY CONTRACEPTION: emergency contraception (also known as the morning after pill) has an 89% success rate. The morning after pill targets what is left of the sperm to stop a woman from getting pregnant.
9. Identify how the contraceptive pill prevents pregnancy. What are the effects it has on a woman’s body?
Contraceptive pills prevent a woman’s reproductive system from releasing an egg, and it helps to make the lining of a uterus less receptive to implantation. The contraceptive pill thickens the mucus around the cervix, making it difficult for sperm to get through. Some side-effects of the contraceptive pill are: nausea, weight gain, sore or swollen breasts, small amount of blood, or spotting between periods, lighter periods and mood changes. More severe effects are: abdominal pains, chest pains, headaches, eye problems and swelling and/or aching in the thighs.
