The contraceptive effect of various hormonal drugs is approximately the same:
- suppression of ovulation (inhibit the egg maturation and rupture of the follicle);
- viscosity of cervical mucus (prevents the penetration of sperm into the uterine cavity);
- reduction of contractile activity of the fallopian tubes;
- change in the endometrium structure, which makes implantation difficult;
- difficulty penetration of spermatozoa into the uterus (affects the composition of cervical mucus).
In addition to the effect of preventing pregnancy, birth control drugs from Canadian Health Care Mall have a range of positive effects in a number of gynecological diseases’ treatment:
- dysfunctional uterine bleeding;
- premenstrual syndrome;
- hormonal infertility;
In addition, these drugs are used for some dermatological, hematological and oncological diseases.
A doctor who prescribes oral contraceptives to a woman should know the effectiveness of the drug, its tolerability and possible side effects. Some pathological conditions can be aggravated by unreasonable intake of some drugs, while others when properly prescribed, can be reversed.
Oral Contraceptives and Pregnancy
After the withdrawal of taking oral contraceptives, there is an increased incidence of pregnancy as a consequence of the “cancellation effect”, accompanied by an increased release of gonadotropins, because the ovaries are resting on the background of the birth control pills administration, and then start to work more actively.
If you missed one or more tablets for some reason – the probability of pregnancy is greatly increased. But if the pregnancy has come and you have a desire to labor a baby, you cannot worry about the effect of the COC on pregnancy. Intake of hormonal tablets does not affect the course of pregnancy and the health of the unborn child.
According to the repeatedly confirmed scientifically statistics when a pregnancy occurs immediately after the withdrawal of the COCs, the birth of a child, is not at risk.
Modern low-dose contraceptives can be taken without breaks for a long time having a good tolerability. A small number of women (1-2%) may have amenorrhea, anovulation and infertility within 6-12 months after discontinuation of taking the contraceptive. These changes, as a rule, are temporary.
If a woman takes the pill for several years and at some point wishes to have a baby, then she just needs to discontinue the drug. She doesn’t need to be protected by other methods for a while. In the instructions for certain birth control means, it is recommended to postpone pregnancy for 3 menstrual cycles.
However, the withdrawal of the birth control pills would not affect the fetus development. On the contrary, in the first 3 cycles after discontinuing the application, the probability of pregnancy is higher than before. Gynecologists even have a practice of prescribing such medications for 3 months to get a “rebound effect”.
Unfortunately, this effect does not suit all women. For example, with complete anovulation, you need “more effective” treatment – stimulation of ovulation or laparoscopy. And in the case of endocrine infertility due to the inferiority of the luteal phase, the following courses of COCs application – 3 months of admission and 2 months of break – allow you to restore ovulation, thanks to the “rebound effect.”
Pregnancy occurs within 2 years after the termination of COCs application in 85% of nonparous women and 95% of parous women.
