Contraceptive methods are many, but some methods of contraception are not safe, easily lead to pregnant women, it is easy to unintended pregnancy following the three unsafe methods of contraception:
1, lactation contraception
The human body, “the king of endocrine” – pituitary is subject to “boss” of hypothalamic control. When the baby nipple sucking reflex so that when the hypothalamus is inhibited, thereby suppressing ovulation. Reduced if the baby sucking the nipple, or mothers affected by environmental change, climate change, changes in mood and sexual implications of the cerebral cortex is likely to be affected by ovulation. As ovulation earlier, in the latter period, some women may be pregnant before the next menstruation, commonly known as “dark pregnant.” According to the survey, there are 5% ~ 1O% of women breast-feeding is inexplicably pregnancy. Postpartum contraception generally use condoms and birth control ring on a suitable, should not take birth control pills, so as not to affect the nursing infant.
2, contraception, menopause
In menopausal women that their menstrual scarce, close to the menopause, there will be no chance of pregnancy to give birth control measures. However, according to Hospital, statistics show that the flow rate of all age groups in order to 4O ~ 45 years old the highest, followed by 2O ~ 24 age group. The reason for women to menopause, although ovarian failure, estrogen and progesterone secretion decreased, but the ovaries may still be ovulation, pregnancy is still possible. The data indicate that, due to unhealthy aging eggs, menopause, pregnancy, the incidence of hydatidiform mole than in women of childbearing age from 4 to 7 times higher, and many who have malignant transformation (malignant transformation of hydatidiform mole or choriocarcinoma). In this regard, women should insist on contraception, menopause, until 1 to 2 years after menopause.
3, rhythm method
Monthly in women of childbearing age 2-3 days after ovulation, conception is most likely. Of these, more than a month 2O days infertility, known as the “rhythm method”. But the “rhythm method” is not safe. Although women’s ovulation period more than in the medium term, but because of the external environment, temperature, mood, health status and other factors, can be advanced or delayed ovulation. Some women can be sexual stimulation occurs when the “additional ovulation.” For this reason, women of childbearing age or long-term use of reliable contraceptive measures as well.
Therefore, we should choose the right method of contraception to avoid pregnancy, to prevent health risk.
