Contraception / IVF
Sample Solution
. Hormonal methods:
These methods work by preventing ovulation (the release of an egg from the ovary) or thickening cervical mucus to make it difficult for sperm to reach the egg. Hormonal methods come in a variety of forms, including:
- Combined oral contraceptives (the pill): These pills contain synthetic versions of the hormones estrogen and progestin, which regulate the menstrual cycle and prevent ovulation.
- Progestin-only pills (minipills): These pills contain only progestin, which thickens cervical mucus and can also thin the lining of the uterus, making it less hospitable for implantation of a fertilized egg.
- Patches: These thin, adhesive patches release hormones through the skin into the bloodstream. They are changed weekly.
- Vaginal rings: These flexible rings are inserted into the vagina and release hormones slowly over a three-month period.
- Implants: These small, thin rods are inserted under the skin of the upper arm and release hormones slowly over a three-year period.
- Injections: These shots contain progestin and are given in the arm or buttocks every three months.
2. Barrier methods:
These methods physically block sperm from reaching the egg. Barrier methods include:
- Male condoms: These thin sheaths are worn over the penis during sex and trap sperm so they cannot enter the vagina.
- Female condoms: These pouches are inserted into the vagina before sex and cover the cervix, blocking sperm from entering the uterus.
- Diaphragms: These dome-shaped cups are inserted into the vagina and cover the cervix. They must be used with spermicide, which is a gel or foam that kills sperm.
- Cervical caps: These thimble-shaped caps fit over the cervix and block sperm from entering the uterus. They must also be used with spermicide.
3. Intrauterine devices (IUDs):
IUDs are small, T-shaped devices that are inserted into the uterus by a healthcare professional. They work by preventing fertilization in several ways, including thickening cervical mucus, making the uterine lining less hospitable for implantation, and sometimes by interfering with sperm movement. IUDs are effective for up to five to ten years.
The best type of artificial contraception for you will depend on your individual needs and preferences. It is important to talk to your doctor about your options to find the method that is right for you.
