Having children is a social task that every couple has to face. Of course, there are some families that choose to be dinky these days. It is the desire of every couple of childbearing age to have a healthy child. In the first three months of pregnancy preparation, both partners should stop smoking and drinking, lead a regular life, eat a healthy diet and exercise in moderation. The female partner should also take folic acid supplements to prevent neural tube abnormalities in the fetus. Couples who are planning to have children should go to the hospital for checkups, collectively known as preconception checkups. The general preconception examination includes gynecological examination, gynecological ultrasound, TORCH (or eugenics four). Cervical cytology (cervical cancer screening), vaginal secretions (optional mycoplasma and chlamydia tests), and micronutrient tests may be performed as needed. If the woman has a known medical condition, additional tests may be performed to make sure that the current condition does not affect the pregnancy. The purpose is to ensure that the woman is in the best physical condition to conceive and raise her offspring, and to achieve the goal of eugenics. There are some women who have abnormal menstruation or already suffer from other gynecological diseases, or have internal diseases and have the requirement to have children, they should go to the hospital for consultation; couples who have already given birth to abnormal fetuses or have 2 or more spontaneous miscarriages or stillbirths, couples who have genetic diseases or family diseases in both spouses or close relatives, should go to the hospital for consultation, and both spouses can be checked for chromosomes, blood types, etc. Genetic counseling should be conducted if necessary to avoid having children The possibility of having offspring with genetic diseases or developmental deformities. If the couple has been free of contraception for one year and has normal sexual intercourse, but cannot achieve a successful pregnancy, the diagnosis of infertility is made, and prompt medical consultation is required. We also remind you to choose a regular hospital instead of illegal clinics or clinics with small advertisements. Infertility is not an incurable disease. You should consult a hospital in time to find the cause. Most infertility patients can have their own children after active treatment. Infertile couples should have both men and women examined at the same time. Generally, the male partner should check whether the semen is normal; the female partner should check whether the ovulation function is normal and the patency of the fallopian tubes. Specifically, the female partner may need gynecological examination, cervical cytology (cervical cancer screening), ultrasound to monitor ovulation, basic endocrine examination (to assess ovarian reserve function and guide endocrine therapy), tubal imaging, hysteroscopy, PPD (tuberculin test), vaginal discharge examination, etc. For those with a history of adverse pregnancy and delivery, chromosomal, autoantibodies and blood group antibodies should be checked on both sides; for other combined diseases, the corresponding tests should be added. Treatment: Patients with ovulation disorders should receive ovulation promotion therapy. Patients with ovarian failure or certain chromosomal disorders may opt for egg donation. Patients with tubal incompetence can choose laparoscopic surgery or in vitro fertilization (IVF). Patients with male factor infertility may opt for artificial insemination or IVF to help them conceive (1st, 2nd or 3rd generation). Patients with azoospermia or certain chromosomal abnormalities may opt for donor sperm. We wish young couples all the best in conceiving healthy offspring and enjoying family life.
