Short-acting oral contraceptives are formulated by synthetic estrogen and progesterone, mainly by inhibiting ovarian ovulation, changing the viscosity of cervical mucus, preventing ** from penetrating, changing the shape of the endometrium, not conducive to the implantation of fertilized eggs, and affecting the peristalsis of the fallopian tubes and other aspects to achieve the purpose of contraception.
Long-acting oral contraceptives are made of synthetic progesterone and long-acting estrogen, and the long-acting estrogen ethinyl estradiol in this type of contraceptive pill enters the human body and is stored in the fat block, and then slowly released, affecting the hypothalamic-pituitary-ovarian axis, thereby inhibiting ovulation and playing a long-acting contraceptive role.
After taking contraceptive pills, the sex hormones in the body increase, and the function of the hypothalamus and pituitary gland is inhibited, so that the secretion of follicle hormone and luteinizing hormone decreases, so the growth and development of follicles in the ovaries are inhibited and ovulation is not possible.
Cervical mucus is produced by the secretion of cervical glands, the secretion function of cervical glands is affected by estrogen in the body, and during ovulation, the secretion of glands increases under the action of estrogen, and the mucus becomes thin and transparent, which is conducive to penetration, during the period of taking birth control pills, the cervical glands are affected by the progesterone in the drug, and the mucus secretion decreases, and becomes thick and turbid, which is not conducive to penetration.
The components of contraceptive pills are basically synthetic progesterone and estrogen, which are mainly used to hinder reproductive ability after taking such drugs, so as to achieve the purpose of contraception.
The endometrium is affected by progesterone and estrogen in the menstrual cycle, showing periodic changes, after taking contraceptives, the estrogen and progesterone in the drug act on the endometrium at the same time, so that it can not develop according to the law of natural changes, there are changes in the proliferative period, and there are changes in the secretion period, and the endometrium of this dysplasia is not suitable for fertilized egg implantation.
The peristalsis of the fallopian tube is affected by sex hormones and has periodic changes, in order to facilitate the normal operation of the egg and the fertilized egg, taking contraceptive pills can interfere with the normal peristalsis of the oviduct cleft ascending tube, accelerate the speed of the fertilized egg in the fallopian tube, and reach the uterine cavity in advance, at this time, the endometrium is not yet mature, which is not conducive to the fertilized egg implantation, so it plays a contraceptive role.

Light has wave-particle duality, i.e., it can be understood as both a wave and a beam of particles moving at high speed at the microscopic level (note, don't think of it as a simple wave and a simple particle here). They are all microscopic, and Einstein named them photons through his research. The wavelength of the red light wave = microns The wavelength of violet light = microns. >>>More
