Contraception, where is the future?

Contraception, where is the future? (1) Progress in male contraceptive research: Currently, there are only two reliable contraceptive methods for men: condoms and seminal tube ligation. Improving condom use is only a matter of concept, not technical progress. In terms of vasectomy research, the current focus is mainly on improving the success rate of reconstruction, including the function of vasectomy and the suppression of fertility due to autoimmune reactions. An important breakthrough in male contraception will be the development of a male contraceptive pill that can interfere with sperm production or eliminate the fertility of sperm. It can control sperm production without damaging other cells penis pumps to treat ed , causing genetic mutations and not losing libido. There have been many progress, but there are also many problems. These drugs have been shown to reduce male fertility. (2) Progress in research on female contraception: The vaginal contraceptive ring is 98% effective in suppressing ovulation. This ring has a plastic heart surrounded by a layer of steroid hormones. Its appearance size is smaller than that of common vaginal diaphragms, making it easier to place into the vagina. The estrogen and progesterone contained in the ring are slowly released and absorbed into the blood through the vaginal wall. This ring has few side effects and does not affect sexual intercourse. In place of daily oral contraceptives rose vibrator , long-acting injectable hormones have been developed as a contraceptive measure. One such injection is now used in many parts of the world. This drug contains synthetic progesterone and suppresses ovulation for 90 days. It is highly effective but has side effects such as weight gain, decreased libido, irregular menstruation, etc. Intrauterine devices are also being improved. For example, tailless IUD can greatly reduce the risk of infection, but it makes it more difficult to check whether it is in the uterine cavity. The application of a new examination technology, ultrasound, can solve this problem. If a contraceptive vaccine is made, it can act to terminate pregnancy during pregnancy, and antibodies to human chorionic gonadotropin have been produced that allow women to act on their presumed hGG. Female hair with hGG antibodies no longer responds to the mechanism of hormone increase in the body after pregnancy and can interfere with the implantation of fertilized eggs and menstrual cramps.
