External use of contraceptive

Some people have side effects of vaginal burning and increased vaginal secretions.

Short-acting oral contraceptive

The advantage of taking contraceptive daily is that the contraceptive effect is the most satisfactory (the failure rate of IUD is twice that of contraceptive) and the side effects are less. Current studies have also shown that oral contraceptive can prevent endometrial and ovarian cancer without increasing the incidence of breast cancer. Its disadvantage is mainly the impact on the cardiovascular system, which has the possibility of increasing the incidence of cardiovascular disease, high blood lipids and thrombosis. In addition, daily use is more troublesome, easy to miss, resulting in contraceptive failure.

Long-term oral contraceptive

This is synthetic estrogen, which is taken once a month. It is simple, convenient and safe. The disadvantage is that it causes an increase in blood pressure, there is a risk of occult diabetes, and the duration of medication is generally no more than 5 years. The effect and side effect of the injection are basically the same.

Leather burying long-lasting contraceptive

When the progesterone drugs are loaded into the silicone tube and implanted under the skin, they can be released from the capsule continuously and slowly horse dildo , thus achieving a long-term contraceptive effect.

As a monthly drug, it needs further observation and has not been used in clinic.

It is best not to use unreliable birth control methods.

Ejaculation in vitro is unreliable.

In vitro ejaculation contraception means that when both husband and wife are having sex, when the man is about to enter the most exciting part of his sexual desire and is about to ejaculate, he will quickly pull out the penis and arrange the semen outside the woman's vagina, in order to achieve the purpose of contraception. This is an ancient method of contraception, in the past best ass , in the absence of contraceptives huge ass , many people use this method of contraception.

Although the method of in vitro ejaculation is simple, it is not reliable and has a high failure rate. The reason for the failure was that a small amount of semen had been injected into the vagina before the man pulled the penis out of the vagina. Because about to ejaculate and ejaculate is a coherent action, the interval between the two is very short, most men can not accurately grasp the opportunity, so that when they are about to reach the most exciting part of sex, they cannot pull the penis out of the vagina in time, so that the semen initially ejected into the woman's vagina, and this part of semen has the largest number of sperm, so it is easy to lead to pregnancy. This is the main reason for the failure of extracorporeal ejaculation contraception.

Washing vagina is very harmful.

Wash the vagina, that is, after sexual intercourse, the woman immediately washes the vagina with water or other liquid to wash away the semen from the body, thus avoiding pregnancy. This method is not reliable because the scope of washing is only for the vagina, but before washing, many sperm may have reached the cervix and uterus. In addition, if you use disinfectant, such as dripping dew, to wash the vagina, it is dangerous, because if the concentration is not good, it may cause burns or inflammation.

The safe period is not safe.

The so-called safe period contraception means to calculate the period of non-conception according to the female ovulation period and the survival time of sperm and eggs in the female reproductive tract, so sexual intercourse is carried out during this period of time, so as to achieve the purpose of contraception. Generally speaking, the egg can survive for 1-2 days after ovulation remote controlled vibrator , and the sperm can survive for 2-3 days in the female reproductive tract. Therefore, it is possible to have sexual intercourse 2-3 days before ovulation and 1-2 days after ovulation. This period is called the easy pregnancy period. Ovarian ovulation is generally within 2 days before and after 14 days of menstruation, so the safe period is about 10 days after menstruation, and 20 days after menstruation to the next menstruation. The nearer the menstrual period, the greater the possibility of contraception.

However, this algorithm is often unreliable, because the time of ovulation is affected by the external environment, climate, mood, health and other factors, resulting in delayed or early ovulation, and additional ovulation may occur. In addition, there is no final conclusion on the maximum survival time of sperm and eggs in the female reproductive tract, so the safety period cannot be calculated accurately, so safe period contraception is not safe.
