Why can't they get pregnant if both of them are normal?

Many couples have been married for many years but still cannot conceive. They go to the hospital for a physical check-up and find nothing wrong. Both husband and wife are normal, so why can't they conceive? Pregnancy is affected by many factors. Sometimes the sperm and egg are both in the same place but just don't meet. Therefore, preparing for pregnancy is a very necessary thing. If both husband and wife are normal but cannot conceive, then they should do the relevant preparations for pregnancy. Paying attention to diet during pregnancy preparation will have a significant impact on the future healthy growth of the baby.

Pregnant mothers and fathers should not only ensure the balance of various nutrients during pregnancy preparation, but also pay attention to supplementing some nutrients. Before pregnancy, you need to supplement folic acid tablets, calcium, iron, zinc and various other nutrients. Men usually look down on fruits and vegetables, thinking that they are just weight loss foods for girls. But they don't know that many vitamins contained in fruits and vegetables are essential for men's reproductive physiology. Some foods high in vitamins can greatly help improve the survival quality of sperm. For example, vitamin A and vitamin E have the functions of anti-aging and slowing down the decline of male sexual function. They also have significant effects on the transformation of sperm and improving the specificity of sperm. Lack of this vitamin can often lead to obstruction of sperm formation.

If men lack various vitamins in fruits and vegetables for a long time, it may hinder the normal growth and development of sex hormones and the formation of sperm, thereby reducing sperm or affecting the normal activity ability of sperm, and even causing infertility. During the pregnancy preparation period, you must pay attention to the prevention of physical diseases and keep warm. If a woman is born with high blood pressure or heart disease, she must first take treatment as the priority, go to a reliable hospital for examination and obtain the doctor's approval before she can go through the pregnancy process. It is imperative to take responsibility for the health of the baby. During the pregnancy preparation period, do not take various drugs containing growth hormones or antibiotics at will, as they will remain in the body and affect the baby.

In addition, women who become pregnant at an older age are more likely to have abnormalities in their bodies than younger women. Therefore, when preparing for pregnancy, you should go to the hospital for a comprehensive health check, including your husband. If there are any abnormalities, you should actively seek medical treatment first to adjust the body to a healthy state. Also get enough sleep every day. Adequate sleep can enhance the body's immune ability and improve the functions of human organs and tissues, especially the urinary system, which is conducive to the production of high-quality sperm and egg combinations.

I can't get pregnant with my second child without any contraceptive measures.

Since you have already given birth to a child, if you haven't conceived a child for a year, it is probably caused by gynecological inflammation. For example, fallopian tube obstruction, pelvic inflammatory disease, cervical erosion, endometriosis, etc. are all causes of infertility. Of course, male prostatitis, sperm survival and quantity, etc. are also possible causes of infertility. Both parties abstain from sex for 3 to 5 days and go to the hospital for a physical examination. Men will undergo semen analysis, while women will undergo six sex hormone tests, basal metabolism, ovarian, and medical immunology tests, etc. It is recommended that you and your lover go to a regular hospital for a comprehensive and systematic examination to determine the cause of infertility and receive targeted treatment.

As we all know, during pregnancy, due to the growth and development needs of the fetus, the pregnant woman's body will undergo a series of changes in each stage of pregnancy. The kidneys, as a key organ, are no exception, and a series of changes have occurred since early pregnancy. The renal blood perfusion flow and tubular filtration rate both increase in the early stages of pregnancy. This change is more pronounced around 20 weeks of pregnancy.
