Infertility is a reproductive disorder caused by various etiologies, representing an adverse reproductive health event for couples of childbearing age. For women, if there is no contraception and they have had sexual intercourse for at least 12 months without conceiving, a diagnosis of infertility can be made. In men, this condition is referred to as sterility. Infertility can be divided into two main categories: primary and secondary infertility. Primary infertility is when a person has never conceived despite not using contraception, whereas secondary infertility occurs when a person has previously been pregnant but fails to conceive again after 12 months of unprotected intercourse.

Infertility is what it means.

I think it's important to first clarify the definition of infertility, which is defined as couples living together for over two years with regular sexual activity, not using contraception, and not conceiving. Those who have never conceived without contraception after marriage are defined as primary infertility, while those who have been pregnant before and then, without using contraception, have not conceived again for two years are defined as secondary infertility. According to the World Health Organization's manual on standard examinations and diagnoses for infertile couples, the clinical standard for infertility is defined as one year. However, currently, we think that individuals who have had regular sexual activity without contraception and have not conceived for over a year should be advised to visit a specialized hospital and consult the gynecology or traditional Chinese medicine departments to investigate the causes of infertility.

Can fallopian tube cysts cause infertility?

If it has been confirmed that there is a fallopian tube cyst, further examination is still needed to determine whether the fallopian tube cyst affects normal conception. If the fallopian tube cyst causes narrowing or blockage of the fallopian tube lumen, it may decrease the likelihood of normal conception or increase the risk of ectopic pregnancy. If the cyst on the fallopian tube does not affect the spaciousness of the entire lumen or cause any blockage of the fallopian tube, it generally will not have any impact on normal conception.

What to eat to regulate the body for cold-induced infertility?

Cold body infertility, in traditional Chinese medicine, is mainly caused by the deficiency of spleen and kidney yang. Clinically, this will manifest as a pattern of deficiency and coldness. At this time, one should first make adjustments through diet. The diet should include more warm foods and less raw, cold, especially frozen foods, and more animal-based foods, which are beneficial for the body, such as beef, lamb, dog meat, fish, shrimp, leeks, pepper, and Sichuan pepper, etc. At the same time, one should also engage in more physical exercise to get the body moving and slightly sweating, which can improve the cold constitution and increase the chance of conception.

Can infertility be inherited?

Regarding the question of whether infertility is hereditary, we cannot generalize. We should analyze specific situations individually. For infertility caused by chromosomal or genetic abnormalities, it may be inherited by offspring. In such cases, one should choose targeted treatments under the guidance of a specialist. However, infertility due to non-genetic factors can often be cured through proactive treatment. Usually, the female can conceive and the condition will not be passed on to the offspring. For better treatment and diagnosis, it is recommended to visit a reputable public hospital locally to get a clear diagnosis and treatment, which can save both time and money.

Why does a chocolate cyst cause infertility?

Chocolate cysts, also known as ovarian endometriomas, are a manifestation of endometriosis. Generally, it refers to the implantation of endometrial tissue on the ovaries, causing local infiltration and invasion, leading to cysts. Because the fluid inside the cyst resembles chocolate, they are called chocolate cysts. Chocolate cysts may cause infertility, for the following reasons: First, chocolate cysts can affect the function of the ovaries, causing ovulatory disorders and ovarian dysfunction. The secretion of estrogen and progesterone is relatively low, and these factors can lead to infertility. Second, chocolate cysts can cause adhesions within the pelvic cavity, affecting the egg-picking function of the fallopian tubes. This factor can also lead to female infertility.
