The main causes of female infertility
(1) Ovulation disorder or non-ovulation: The combination of egg and sperm to form a fertilized egg is the most basic requirement for fertility. Women with ovulation disorders or anovulation cannot release normal eggs, so pregnancy is impossible.
If women have ovarian dysplasia, ovarian cysts, premature ovarian failure or polycystic ovary syndrome, etc., it will lead to ovarian dysfunction, thus causing ovulation disorders. Excessive dieting can also lead to significant weight loss, which can lead to ovarian dysfunction, menstrual disorders, amenorrhea, or ovulation disorders.
(2) Fallopian tube occlusion or adhesion:The fallopian tube has the function of transporting sperm, ingesting eggs, and fertilizing eggs. Therefore, fallopian tube obstruction or dysfunction can also cause infertility. Common causes of fallopian tube occlusion or adhesions are salpingitis or endometriosis. If the fallopian tubes are blocked and the sperm and eggs cannot meet, conception will not be possible.
(3) Immune factors: If the woman’s cervical mucus or serum contains anti-sperm antibodies, Difficulty conceiving.
(4) Gynecological inflammation: If women suffer from vaginitis, cervical erosion, endometrium inflammation, adnexitis, pelvic inflammatory disease or other sexually transmitted diseases, the inflammatory exudate destroys the local environment, kills sperm or causes adhesions, which will also affect pregnancy to varying degrees.
(5) Abnormal development of reproductive organs: Uterine dysplasia, abnormal uterine development (such as no uterus Or immature uterus), hymenal atresia, vaginal or uterine malformations can cause female infertility.
(6) Psychological factors:Including anxiety, fear, pessimism, tension, low self-esteem, fantasy, and depression, which can all lead to infertility. The reasons are related to lack of sexual knowledge.
Main causes of male infertility
(1) Abnormal semen
① No sperm or too few sperm, congenital testicular development disorder or serious lesions of testicles and vas deferens, mostly permanent azoospermia. If sexual life is too frequent, spermatogenic function will result First-degree failure is mostly caused by a decrease in sperm rather than a total absence of sperm, and it is temporary. It can be recovered by reducing the frequency of sexual intercourse.
②Poor sperm quality, too many inactive or dead sperm in the semen , or the sperm motility is very poor, or the deformed sperm exceeds 30%, which can often cause infertility.
③The physical and chemical properties of the semen are abnormal. Normal semen quickly gels into a jelly after ejaculation. In the next 15 years, ~30 minutes and all liquefies. If the semen does not solidify after ejaculation, or the liquefaction is incomplete, it often indicates that there are lesions in the seminal vesicles or prostate. In addition, some bacteria and viruses that infect the reproductive tract can also cause changes in semen composition and cause infertility.
(2) Reproductive system diseases: Acute and chronic infections can occur in the reproductive system. Acute infections commonly include acute orchitis , epididymitis, seminal vesiculitis, urethritis, prostatitis, etc., can all be caused by the pathological changes of acute inflammation, which can affect its structural and functional changes, causing problems with the quality and transportation channels of sperm and affecting fertility. Chronic inflammation can be caused by the acute inflammation phase. Caused by incomplete treatment, but most often caused by specific infections, such as gonorrhea, syphilis, varicocele, tuberculosis and other diseases can cause infertility. Sexually transmitted diseases can affect the production, development and motility of sperm. External reproductive organs Injury or deformity can also cause infertility.
(3) Sexual dysfunction:Impotence, infertility Sexual intercourse disorders such as ejaculation or retrograde ejaculation can also cause infertility. Causes of impotence include psychological, vascular, endocrine and drug effects.
(4) Endocrine disorders: Mainly manifested in testicular secretion dysfunction, testicular stromal tumors or testicular secretion hyperactivity, and pituitary secretion dysfunction. Early pituitary hyperfunction can cause hypersexuality, and then Loss of sexual desire occurs, leading to impotence.
Hypopituitary function can cause loss of sexual desire, testicularPill atrophy; thyroid function disorders and adrenal secretion disorders will affect sperm production.
In addition, severe malnutrition, certain systemic diseases, frequent exposure to radiation, high-temperature operations, drug poisoning, etc. can all lead to infertility.
Causes between husband and wife that affect female infertility
( 1) Unscientific sex life: Unscientific sex life has the following symptoms. Some people never have orgasm during sexual intercourse. Although orgasm is not an absolute condition for conception, a large amount of secretion will be produced during orgasm. , which is conducive to the forward movement of sperm. Some people have incorrect sexual intercourse methods. They just place the glans at the vaginal opening without inserting it. The semen cannot be ejected directly near the cervix. Some people have sexual intercourse too few times, and the time of sexual intercourse does not coincide with the ovulation period. These can affect conception. In addition, frequent sexual intercourse may also affect the quality and quantity of sperm. Although men produce large amounts of sperm every day, mature sperm must develop in the testicles for a period of time. If you are eagerly waiting for the arrival of your baby, it is best not to have sex once or several times a day to give the sperm enough time to mature and allow it to better combine with the egg.
(2) Too much mental stress:If you are too anxious, worried or too nervous, it may also cause Infertility.
(3) Immune factors:Semen contains a variety of proteins, which can serve as antigens. It is absorbed by the cervical epithelium in the female cervix, resulting in an immune response, and then produces antibodies in the female blood or vagina. This antibody can agglutinate or brake sperm, affecting sperm movement and causing infertility.
