A contraceptive injection contains the synthetic form of the hormone, progestogen. One injection can last up to 8-12 weeks depending on what type you're going for. Although, it's a reversible contraception, it can take up to a year for the effects of the injection to wear off. Depo-provera is a natural hormone that is usually produced by the ovaries. It prevents pregnancy by stopping ovulation, thickens cervical mucosa to prevent sperms from moving into the uterus and thins the uterine lining to avoid implantation of a fertilized egg. Some changes in the menstrual period may happen: bleeding or spotting between periods, an increase or decrease in bleeding or no period at all.
ü Abdominal pain
ü Blood clots
Permanent method of contraception whereby the person is rendered infertile. It involves blocking of the duct that carries the egg and sperm. Thus, the ovum and the sperm cannot meet and no fertilization takes place. In males it is called vasectomy and in females it is called Tubectomy. Female sterilization can be done by open method or by laparoscopy
Vasectomy: is a very simple, day care procedure. It can be done by incision method or by no scalpel (no cut) method. No cut method has a lower infection risk and heals in a short time. Vasectomy does affect orgasm or ejaculation.
Tubectomy: is a permanent method where both fallopian tubes are blocked or cut, so that the ovum or egg cannot travel from the ovaries to the uterus for fertilization with the sperm. It can be done by open method or by laparoscopy. In open method, the fallopian tubes are cut and tied, while in laparoscopic method the tubes are blocked by a clip, thereby preventing the ovum from reaching the uterus.
Both tubectomy and vasectomy can be reversed but the results cannot be guaranteed.
The contraceptive patch contains both estrogen and progestogen and works the same way as the implant and the injection. However, the patch needs to be changed at least once a week. But it sure is one of the easiest options to go for.
