What posture does the roommate who wants to have a girl use? Foreign research shows that it is easy to have more sperm in boys and less sperm in daughters during pregnancy. According to this reasoning, if you want to have a boy, you need to abstain from sex a few days before ovulation, so that men can produce the largest amount of sperm and improve the chances of conception between Y sperm and eggs. If you plan to have a girl, you don't need to abstain from sex, just keep the normal S frequency (for example, once every 3 days), preferably 2 days before ovulation.
In the S posture, it is suggested to adopt the traditional male-female posture as far as possible, and the entry into the water needs to be shallow. At the same time, avoiding orgasm will also reduce the chances of getting pregnant with a male baby. Note that one week after s may be pregnant, and it is best to abstain from sex.
1, diet adjustment
Women's vaginas are generally acidic. If alkaline substances are secreted during orgasm, it is more suitable for Y sperm to survive. Anyone who wants to have a boy must pay attention. If you want a girl, you should keep an acidic environment in your body. Diet control is to divide food into acidic, alkaline and neutral foods. Men eat acidic food and women eat alkaline food, which helps to have boys. Men eat more alkaline food and women eat more acidic food, which is beneficial to girls. A reasonable diet is good for health.
Step 2 find a suitable time to have sex
The environmental temperature one month before fertilized eggs are combined, that is, the environmental temperature of boys and girls one month before sexual intercourse, is an important factor affecting the sex of babies. High temperature environment is easy to bring up boys and babies, and low temperature environment is easy to bring up girls and babies. High temperature will affect the X chromosome of sperm, making it difficult for baby girls to be born; Low temperature will affect the Y chromosome of sperm, making it difficult for a baby boy to be born. Therefore, if you want to have a boy, it is best to conceive in summer, and if you want to have a girl, try to conceive in winter.
3, change the acid and alkali
Sperm with X and Y chromosomes swim at different speeds in different pH environments: sperm with Y chromosome is more active in alkaline environment, while sperm with X chromosome is more active in acidic environment. Therefore, if couples want a girl, they can dilute acetic acid with a small amount of clean warm water and then rinse the woman's vagina to make it acidic. On the contrary, have a boy.
Step 4 create an orgasm
Normal women's vagina is usually strongly acidic, which will become acidic after the first orgasm and weakly acidic after the second orgasm. Semen is alkaline, which will enhance the alkalinity of vagina when women reach orgasm, and is more suitable for the growth of sperm with Y chromosome. Therefore, people who want to have a boy should try their best to create an orgasm and increase the chance of making the vagina alkaline.
How is the bleeding after the same room? External reproductive tract injury
1, hymen injury. The most common is the rupture of hymen during the first sexual intercourse. This kind of bleeding usually occurs during sexual intercourse. There may be pain and bleeding at the same time, and the amount of bleeding is usually not much. If the injury is not serious, the bleeding will stop soon. However, sometimes the rupture of hymen just damages the blood vessels in this part, so there will be more bleeding, and it is necessary to compress and stop bleeding (such as using clean cotton balls or gauze and clean towels). ) even go to the hospital for treatment.
2, vaginal laceration. Vaginal bleeding is found during or after sexual intercourse, with large amount of bleeding, difficult to stop and long bleeding time. Vaginal laceration often occurs in involuntary sexual intercourse or very rough sexual intercourse. Vaginal laceration is also seen in vaginal malformations, such as vaginal mediastinum, diaphragm, double vagina and vaginal stenosis. After vaginal plastic surgery, hymen repair, vaginal tumor resection and hysterectomy, when the vaginal wound is not healed well, sexual intercourse is also easy to cause damage. Improper sexual posture and posture can also lead to vaginal injury and bleeding. The amount of bleeding is related to the location and degree of injury. Once there was an anonymous man who was raped and severely lacerated from the back wall of vagina to the fornix of vagina, and suffered a lot of bleeding. Six hours later, I went to the hospital. When I saw a doctor, I had hemorrhagic shock such as pale face, rapid pulse and decreased blood pressure.
Inflammation of external reproductive tract
1, cervical polyps. Cervical polyps can occur when the cervix is stimulated by chronic inflammation for a long time. One or more small granulation tissues with pedicles grow on the cervix, which look like bean sprouts petals, and the largest is like fingers. Polyps are crisp and tender, and they bleed when touched, so there may be bleeding after sexual intercourse. This bleeding is usually bright red.
2. Cervical cancer. Hemorrhage after sexual intercourse is the earliest symptom. Because there are many small blood vessels in the cancer focus and the tissue is fragile, the capillaries will bleed and rupture due to injury after each sexual intercourse. If the cancer develops further, it will bleed more easily.
3. Endometriosis. Some endometriosis grows in the cervix, showing blue-purple nodules. If you encounter this blue-purple ectopic nodule during sexual intercourse, it will cause bleeding. Bleeding is generally less, dark red, and abdominal pain often occurs after sexual intercourse.
4, pelvic inflammatory disease. Pelvic inflammation can make pelvic congestion. If the endometrium is congested and edematous, the congested endometrium can be rented out after sexual intercourse, but this kind of opportunity is rare.
5, cervicitis (erosion). 90% of married women suffer from cervicitis. Cervicitis is divided into three types according to the degree of cervical erosion: mild, moderate and severe. For those with moderate or above cervical erosion, the man's penis and glans rub against the cervix during sexual life, which can cause injury and bleeding. Because this kind of bleeding is small, it will not flow out immediately, but will accumulate in the vagina, and the color of blood will change from fresh to old. So when it came out the next day, the blood was dark red.
