Why can't I get pregnant without contraception?

We all know that pregnancy is a matter between two people, and the combination of sperm and egg cells can achieve the effect of conception. Many young couples are in good health and want to have a baby of their own, so they do not take any contraceptive measures in their married life, but they still cannot get pregnant. There are many reasons for not being able to get pregnant, so let us now understand why you can’t get pregnant without contraception?

The main causes of female infertility:

Ovulatory dysfunction is manifested as the absence of ovulation during the menstrual cycle, or although ovulation occurs, the corpus luteum function is not sound after ovulation.

Fallopian tube factors: Fallopian tubes that are too long or narrow, fallopian tube blockage, water accumulation or adhesions will hinder the movement of sperm, eggs or fertilized eggs. Fallopian tube disease can account for 25% of female infertility and is an important cause of infertility.

Ovarian factors: Ovarian hypoplasia, corpus luteum insufficiency, premature ovarian failure, polycystic ovary syndrome, ovarian tumors and other factors that affect follicle development or egg discharge can cause infertility.

Cervical lesions: Congenital abnormalities, occlusion or stenosis, polyps, erosions, tumors, adhesions, etc. of the cervical canal can affect the passage of sperm; the presence of anti-sperm antibodies in cervical mucus is not conducive to sperm penetration of the cervical canal or completely incapacitates the sperm. Nowadays, radiofrequency interventional therapy can effectively treat cervicitis, cervical erosion, polyps and other problems.

Congenital abnormalities in the development of the reproductive organs or acquired genital organ diseases hinder the patency and function of the reproductive tract from the vulva to the fallopian tube, hinder the meeting of sperm and egg, and lead to infertility.

Immunological factors: refers to the presence of anti-sperm antibodies in the female reproductive tract or serum, which cause sperm to agglutinate each other, lose vitality or die, leading to infertility or sterility. In addition, some infertile women have antibodies against their own egg zona pellucida in their serum, which can prevent sperm from penetrating the egg and fertilizing it, and can also cause infertility.

Infertility caused by sexual dysfunction, lack of sexual knowledge, systemic diseases and unknown reasons accounts for about 1/3 of the causes of infertility.

There are many reasons for male infertility. Congenital problems are more serious, while acquired problems are easier to overcome. As long as the treatment is appropriate, there is still a chance to have a baby again.

Sexual dysfunction includes impotence, premature ejaculation, spermatorrhea, anejaculation, etc. Anejaculation accounts for 35% of the causes of male infertility.

Taking medical diseases as an example, diabetes and some nervous system diseases can cause impotence and also lead to reduced sperm production. Epididymitis and prostatitis caused by pulmonary tuberculosis can cause problems in sperm transport. If the patient often suffers from chronic sinusitis, chronic bronchitis and bronchiectasis, these symptoms are sometimes related to asthenospermia or cystic fibrosis (causing bilateral vas deferens defects). Mumps after puberty can sometimes cause orchitis, which causes the testicles to lose their ability to produce sperm.

Long-term and excessive use of tobacco and alcohol can cause a decline in semen quality. Smoking marijuana and heroin can also affect male fertility. Have you had a fever over 38.5℃ in the past six months? If the fever is over 38.5℃, it will inhibit sperm production for up to six months, and the fever will also damage sperm DNA.

Abnormal semen quality, including oligospermia, azoospermia, necrospermia, asthenospermia, polyspermia, too little semen volume and semen liquefaction failure. Oligospermia accounts for 15.4% of the causes of male infertility.

Immunological factors: refers to the presence of anti-sperm antibodies in male serum or seminal plasma, which produces autologous anti-sperm immune response and leads to immune infertility.

Varicocele causes 12% of male infertility.

Some drugs can cause a temporary or permanent decrease in sperm count, such as some hormonal preparations, such as male hormones, female hormones, steroids, and some drugs for treating urinary tract infections, such as Nitrofuratoin; drugs for treating gout, such as colchicine, and drugs for treating ulcerative colitis, such as Sulphasalaz inel (a xanthine), which can cause a temporary decrease in sperm count. Pregnant women who consume or are exposed to female hormones or female hormone-like additives may give birth to boys with genital abnormalities or low testicular spermatogenesis. Taking male hormones to improve your physique can also cause a decrease in sperm count.

Some chemotherapy drugs used to treat cancer can also affect fertility; radiation therapy can cause irreversible damage to reproductive function. For these patients, sperm is frozen in advance for future use.

Reproductive tract infections, congenital anomalies, systemic diseases and infertility caused by unexplained causes.

In addition, whether you have received general anesthesia for surgery or undergone testicular biopsy in the past six months, these will temporarily suppress the testicular spermatogenic ability. Patients who have undergone prostatectomy or bladder neck obstruction surgery may sometimes experience retrograde ejaculation and azoospermia. Stenosis of the urethra due to trauma may also prevent semen from being ejaculated.

Hypospadias or epispadias can sometimes cause difficulty ejaculating after reconstructive surgery. Hernia surgery can sometimes cause blockage of the vas deferens. Vasectomy or vasectomy can cause the production of anti-sperm antibodies, which reduces the effectiveness of vasectomy recanalization. If semen quality does not improve after successful varicocele surgery, other causes of infertility should be identified.

The above is why you can’t get pregnant without contraception? The detailed answer is that inability to conceive is not just one person's problem. There are many family disputes caused by this reason. For the sake of family happiness and marital harmony, friends who cannot have children without contraception are advised to get checked in time so that the problem can be solved as soon as possible and treatment can be received as soon as possible.
