Among these 50 million patients, 50% are women, 40% are men, and about 10% are cases involving both partners.

What are the precautions for infertility?

For women with infertility, it is first necessary to determine the survival rate of the man's sperm by conducting a sperm test. Additionally, women need to undergo routine examinations and follicle checks. If there are no issues found, a fallopian tube examination should be done for the woman. In daily life, it is important to ensure adequate sleep and to pay attention to rest and avoid alcohol and tobacco. Furthermore, it is crucial to eliminate tension, adjust one’s mindset, and adopt a positive attitude. Bad habits such as staying up late and pulling all-nighters need to be changed.

The difference between infertility and sterility

In clinical practice, we often mention infertility and sterility, so what is the difference between them? Let us take a look. Infertility refers to a condition where a couple has regular sexual intercourse, does not take any contraceptive measures, and the duration reaches over a year, yet the female cannot become pregnant; this is called infertility. If the male can cause the female to become pregnant, or has previously impregnated a woman, but she cannot carry a baby to term, we call this sterility. This is the difference between infertility and sterility.

Classification of the Causes of Infertility

For infertility, it is important to conduct relevant tests as early as possible while young, to receive effective treatment promptly, and to complete childbirth at the earliest. Firstly, male testing should be conducted because the probability of male infertility is also high, and the tests for males are relatively simpler. Afterwards, the causes in females should be investigated, such as monitoring ovulation and conducting endocrine tests for ovulation. Then, the condition of the endometrium should be examined, and a hysterosalpingography should be performed between the third and seventh days of a clean menstrual period to see if this factor contributes to infertility. Subsequently, various biochemical tests, such as immune function and pre-thrombotic state, should also be considered.

How is infertility caused?

Infertility can occur if there is an issue with either partner. The main factors causing infertility in women include ovulation disorders, fallopian tube factors, and abnormal endometrial receptivity. The primary factors causing infertility in men are abnormal spermatogenesis and ovulation disorders. Common etiological diagnoses generally include ovulation disorders, abnormal semen, fallopian tube abnormalities, unexplained infertility, endometriosis, and other immunological infertility. Additionally, cervical factors can also lead to infertility, such as cervical stenosis, which accounts for more than 5% of cervical factors.

Can pelvic effusion cause infertility?

Usually, pelvic effusion in women does not lead to infertility. For instance, physiological conditions in women, such as during the menstrual period or around ovulation, can lead to a small amount of leakage in the pelvic cavity. During an ultrasound, this may appear as a small amount of pelvic effusion, which is usually absorbed normally and does not affect pregnancy. However, if a woman's pelvic effusion is due to inflammation, and this inflammation affects the fallopian tubes or ovaries, causing inflammation in these areas, it might impact the woman's ability to conceive normally.
