Azoospermia

Postby markus » Thu Jun 21, 2018 6:10 am

Azoospermia is a violation of spermatogenesis, characterized by the absence of sperm in the seminal fluid. Depending on the causes, obstructive and non-obstructive azoospermia are distinguished. Azoospermia is accompanied by the inability to conceive naturally, and in some cases - with the help of assisted reproductive technologies. Azoospermia is diagnosed during the examination of the reproductive status of a man (ultrasound, testicular biopsy, determination of hormone levels, spermogram, ASAT).

Azoospermia is a form of male infertility caused by the lack of sperm in the ejaculate. In andrology and urology there are several variants of spermatogenesis disorders: oligozoospermia, asthenozoospermia, teratozoospermia, azoospermia. In addition, meet combined forms of pathology: oligoasthenozoospermia, oligoarthropathy, asthenoteratozoospermia, etc. of all the factors of infertility in men for a fraction of azoospermia accounts for about 10-20%. Pathology of sperm, including azoospermia is always a reflection of the problems of male reproductive health, so the main efforts of specialists should be aimed at identifying and eliminating the causes of this condition

Spermatogenesis - the process of formation and maturation of male germ cells begins in the puberty period and continues until old age. The formation of sperm occurs in the twisted testicular seminiferous tubules and includes three successive phases: proliferation of spermatogonia, meiosis and spermiogenesis. The most active this process takes place at a temperature of 34°C, which is provided by the anatomical location of the testicles in the scrotum, outside the abdominal cavity. The final maturation of sperm occurs in the epididymis. The duration of the full cycle of spermatogenesis in men is about 73-75 days.

All sorts of adverse factors can disrupt the formation and maturation of sperm, leading to various forms of pathospermia, the most common among which are:
oligozoospermia-decrease in the number of live sperm (less than 20 million in 1 ml of ejaculate)
asthenozoospermia - the presence of less than 50% of sperm with movement of type 1 (progressive linear) and type 2 (slow linear or progressive nonlinear) or less than 25% of sperm with movement of type 1. The number and form of sperm in this normal.
teratozoospermia-more than half of the sperm have abnormalities in the structure of the head and tail. Mobility and number of cells are not changed.
azoospermia-sperm are absent in the seminal fluid.

Given the causes of azoospermia may be obstructive, non-obstructive (secretory) and temporary. The basis of obstructive forms of azoospermia is the obstruction of the seminal tract, with the result that sperm cannot enter the ejaculate. In this case, male sex cells are formed in sufficient quantities, have normal morphology and mobility. The causes leading to obstructive azoospermia may be congenital anomalies (aplasia of the VAS deferens), inflammatory processes (orchitis, epididymitis, vesiculitis, prostatitis), injuries of the scrotum, varicocele, inguinal hernia, urethral stricture, operations on the organs of the scrotum (vasoresection, hernia, operations with hydrocele)

When secretory (non-obstructive) azoospermia initially disturbed the formation of sperm in the testicles. Factors causing such a state, can serve as bilateral cryptorchidism, mumps complicated by orchiepididymitis, tumors of the testicles, radiation exposure, toxic effects of salts of heavy metals and pesticides. Violation of spermatogenesis by type of secretory and obstructive azoospermia may occur in hypogonadism, cystic fibrosis, diabetes, celiac disease, pituitary tumors, spinal injuries, syphilis and other diseases.

Temporary azoospermia is characterized by transient functional disorders of the sexual glands and can develop against the background of acute diseases, stress, taking medications (steroid hormones, antibacterial and antitumor agents), frequent visits to saunas and baths. A temporary decrease in sperm production is observed in sexually active men with frequent sexual acts.

The main specific symptom of azoospermia is male infertility. In this case, the sexual function of a man can remain unbroken. Other clinical symptoms accompanying azoospermia are associated with the underlying disease. So, when the hypogonadism in men is defined by the lack of development of secondary sexual characteristics: sparse body hair, body type in the female, gynecomastia. Secretory azoospermia is often accompanied by testicular hypoplasia, micropenis, decreased libido, erectile dysfunction.

In various forms of obstructive azoospermia, a man may be concerned with discomfort, pain, swelling or swelling of the scrotum. When palpation, the testicles of normal size and shape are determined, and the appendages of the testicles are increased due to the accumulation of sperm in it. Obstructive azoospermia may be accompanied by retrograde ejaculation.

The causes and form of azoospermia can be established only by specialists (andrologists, urologists, endocrinologists) on the basis of a comprehensive examination of the male reproductive system. When collecting anamnesis, the frequency of sexual activity and the duration of the period of infertility, past diseases, occupational hazards, the patient's lifestyle and other factors are specified. At physical examination, the type of physique, the severity of secondary sexual characteristics, the state of the external genitals are estimated
