What can a man do to make a woman pregnant?

Men need to pay attention to sperm quality, timing of intercourse and the health status of both partners to improve their partner's chances of pregnancy. The main methods include adjusting lifestyle, optimizing the frequency of intercourse, checking for reproductive diseases, supplementing necessary nutrients and reducing psychological stress.

1. Improve sperm quality:

Sperm motility and quantity directly affect the success rate of pregnancy. Avoid long-term high-temperature environments such as hot springs or wearing tight pants, and reduce the intake of tobacco and alcohol. Both nicotine and alcohol in tobacco will reduce sperm activity. Daily diet can increase the intake of zinc, oysters, nuts, vitamin E, dark vegetables and folic acid animal liver. These nutrients are essential for sperm production. Obesity may cause hormone disorders, and it is recommended to control weight through aerobic exercise.

2. Grasp the ovulation period:

The 48 hours before and after a woman's ovulation day is the golden window for pregnancy. The day of ovulation can be determined by monitoring the basal body temperature when the body temperature rises by 0.3-0.5°C after ovulation, observing the egg white-like stringiness of cervical mucus during ovulation, or detecting the peak value of luteinizing hormone with ovulation test paper. It is recommended to have intercourse on alternate days during the ovulation period, which can not only ensure adequate sperm reserves, but also avoid a drop in sperm concentration caused by frequent ejaculation.

3. Eliminate disease factors:

Varicocele may lead to increased scrotal temperature and testicular hypoxia, increasing the rate of sperm abnormalities； Chronic prostatitis changes semen composition. If pregnancy preparation is unsuccessful for more than 1 year, routine semen examination is required to pay attention to sperm density, motility and morphology, six sex hormones and reproductive system ultrasound. After diagnosis, drug treatment such as levocarnitine can be used to improve sperm motility or microsurgery can be used to perform high spermatic vein ligation.

4. Optimize the way to have sex:

Using the missionary position or the doggy position can help the semen get closer to the cervix. After intercourse, a woman can prolong the retention time of semen by raising her buttocks and lying still for 30 minutes. Avoid using lubricants containing spermicides, and prefer abstinence for 3-5 days before ovulation to accumulate high-quality sperm. Excessive tension may trigger functional erectile dysfunction, and it is recommended to relieve anxiety through meditation or partner massage.

5. Collaborative pregnancy preparation management:

Both parties jointly conduct pre-pregnancy examinations, and women need to check for problems such as polycystic ovary syndrome and fallopian tube blockage. During pregnancy preparation, take a multivitamin containing 400 micrograms of folic acid. Men can add coenzyme Q10 to improve mitochondrial function. Establish a regular schedule and ensure 7-8 hours of sleep a day to avoid disruption of melatonin secretion caused by staying up late and affecting fertility hormone levels.

During pregnancy preparation, it is recommended that both parties maintain moderate-intensity exercise, such as brisk walking or swimming, 3-4 times a week to promote pelvic blood circulation. Add foods rich in omega-3 fatty acids such as salmon to your diet and reduce your intake of trans fatty acids. Avoid contact with environmental endocrine disruptors such as bisphenol A and certain plastic products. If you try not to get pregnant for 6 months, it is recommended to go to a reproductive medicine center for a systematic evaluation. Men over 40 years old should consider directly testing the semen DNA fragmentation rate. Maintain a positive attitude and avoid the psychological burden caused by making childbirth a task.
