What does infertility mean? Infertility refers to not being pregnant, infertility refers to not having children, but infertility refers to being pregnant but not giving birth to a healthy baby.
The common causes of infertility are abnormal fertilization (male infertility), abnormal ovulation or abnormal egg transfusion (female infertility) and immune infertility (male and female infertility). The common causes of infertility are abortion, ectopic pregnancy and stillbirth. Infertile women are more likely to have miscarriage, ectopic pregnancy and stillbirth after treatment, so infertility itself "breeds" the possibility of infertility.
The causes of female infertility include hymen atresia, diaphragm and congenital absence, which will hinder sexual life. When suffering from severe inflammation, a large number of pathogenic microorganisms and white blood cells devour * * *, resulting in infertility.
Cervical factors, cervical infection, inflammation or decreased estrogen level can lead to a large number of white blood cells in cervical mucus or sticky texture, which will affect pregnancy. Suffering from cervical polyps will hinder * * *, leading to infertility.
Uterine factors: The normal uterine position is to lean forward and bend forward, and the cervix is backward. After * * * *, the cervix is soaked in the * * * pool, which is beneficial to pregnancy. If the uterus flexes backward and the cervix is upward, it will affect the entry of * * * into the uterine cavity, leading to infertility, and will prevent pregnant eggs from landing when suffering from endometritis.
Tubal factor Tubal obstruction has always been the main cause of female infertility. When the fallopian tube is inflamed, mucosal secretion decreases, the lumen adheres, and the peristalsis of the whole fallopian tube weakens, which not only leads to infertility, but also induces abnormal pregnancy. When suffering from pelvic endometriosis, it can also cause tubal adhesion and distortion and infertility.
Ovarian factors, such as congenital ovarian deficiency, polycystic ovary or premature ovarian failure, and oophoritis, can affect ovarian ovulation and infertility.
Causes of male infertility Spermatogenic disorders lead to testicular dysplasia, spermatogenic dysfunction or sexual organ differentiation, abnormal sex chromosomes or autosomal genetic diseases;
Bilateral cryptorchidism was not treated in time; Testicular diseases, such as tuberculosis, tumor, mumps complicated with orchitis and varicocele, cause testicular spermatogenic dysfunction;
Systemic chronic diseases, endocrine disorders such as pituitary hypofunction, congenital adrenal hyperplasia, hypothyroidism, etc. It can inhibit sperm production by affecting the function of hypothalamus-pituitary-gonad axis;
Environmental factors such as exposure to radioactive substances, high-temperature operation, bad habits including smoking, excessive drinking, taking certain drugs, etc. will damage the spermatogenic epithelium, which will jointly lead to spermatogenesis disorders, resulting in azoospermia, oligozoospermia, poor mobility and increased deformity rate.
Spermatogenic function of testis is abnormal, but due to various reasons, * * * cannot enter the woman's body normally, leading to infertility. Common reasons include
When any part of epididymis, vas deferens, vas deferens and urethra is blocked or obstructed due to deformity and inflammation, it can affect the discharge of * * *; Retrograde * * *, the injected * * * enters the bladder through the posterior urethra and cannot enter the female * * *. In these two cases, there is no * * * or less * * * syndrome, and inflammation will also affect * * * liquefaction and * * * activity.
* * * Too small, hypospadias and other reproductive tract malformations lead to * * * failure, or * * * inflammation, injury and scrotal edema hinder normal * * * or lead to * * * abnormality;
* * *, abnormal seminal plasma: Anti-self * * antibodies produced in the body can cause male infertility, and the discharged * * * cannot pass through cervical mucus due to self-agglutination.
The immune factor * * * of male and female infertility consists of * * * and seminal plasma. When the components of * * * are absorbed into women, the body will produce antibodies against these components, which are distributed in uterine fluid, blood and * * * secretions, and these antibodies will cause * * *. It is difficult for * * * to ascend and fertilize. Sometimes, even if it can be fertilized, the fertilized egg will die during development. In addition, if * * * reacts with antibodies after reaching the uterine cavity, histamine can be released, which makes the uterus contract strongly and affects the normal pregnancy process.
Mental factors Sexual function is closely related to mental and psychological factors, and is inseparable from reproductive function. Women's long-term psychological state of tension, anxiety and fear will not only cause autonomic nervous dysfunction, but also affect the secretion of sex hormones, leading to reproductive dysfunction, which is manifested as anovulatory menstruation, scanty menstruation, amenorrhea or functional uterine bleeding, as well as tubal spasm and sticky cervical mucus, which is not conducive to the penetration of * * * *. For men who have been in a state of depression and fear for a long time, their * * * generation disorder, * * * decrease, and their death * * * increase.
Malnutrition with serious nutritional factors can lead to testicular spermatogenesis and ovarian ovulation dysfunction, resulting in oligospermia or sexual dysfunction, oligomenorrhea and even amenorrhea. The physiological functions of men and women are normally regulated by hormones secreted by hypothalamus-pituitary-gonadal axis, among which pituitary gonadotropin plays a leading role in regulating the physiological functions of testis and ovary and maintaining normal menstruation. Most of the hormones secreted by hypothalamus are protein, so the serious lack of nutrients, especially protein and vitamins, will affect the anabolism of the whole body, especially the synthesis of protein. The low nutritional status of the whole body will inevitably damage the function of pituitary gonadotropin synthesis and secretion.
Infertility is an important problem that affects the physical and mental health of men and women. If not treated in time, it will not only affect the patient himself, but also hurt the feelings of husband and wife and family happiness. So what does infertility mean? What are the causes of infertility?
Other reasons for infertility Sexual disharmony will also have an impact on pregnancy, which is common in the following situations:
The man has erectile dysfunction or retrograde * * *, and these unsuccessful sexual intercourse make the egg cells and * * * unable to combine, resulting in infertility;
Women avoid * * because of * * pain, * * spasm and frigidity, which leads to the decrease of pregnancy rate;
Physical and mental reasons change the function of reproductive organs, such as the influence of emotions on menstruation, and the pressure of tubal spasm will also affect the chances of pregnancy;
Too little sex life is not suitable for pregnancy, while too much sex life is easy to reduce the quality of * * * *, and it is easy to miss ovulation, increase the chance of infertility, and form a vicious circle.
