Abnormal sperm from the infertile

Posted by sldol on November 3, 2008 in Venereal Disease

1, semen volume is too small

Under normal circumstances, the normal male ejaculation each about 2 ~ 6 ml about ejaculation and the number of ejaculation frequency of a certain relationship. Semen volume of less than 1 ml per volume of semen as too little.

Cause: the reasons for the reduction of semen: 1, She Jingguan obstruction or congenital lack of seminal vesicle caused 2, or pituitary Leydig cell disease, resulting in the reduction or gonadotropin hormones decrease from reduced sperm production, 3, reproductive tract infection Disease can also cause damage to the subsidiary gonadal function, reduced sperm production.

Second, semen liquefied extended

In normal sperm injection at liquefied state, immediately after the formation of clots or Jiaodong Zhuang, at 37 degrees in a water bath 5 ~ 20 min after the solidification of semen into a liquefied state, and the phenomenon known as liquefaction of semen. If this process is greater than 1 h, known as the semen liquefied prolonged.

Cause: the coagulation of semen from the seminal vesicle is caused by a coagulation protein. And liquefied is secreted by the prostate of a series of protein enzyme that is the result of liquefaction, prostate and seminal vesicle inflammation, it secretion disorder, semen coagulation factors that increase or decrease liquefied factors, resulting in semen is not liquefied. Semen so that sperm was not liquefied mucus network, hinder women in their reproductive tract in exercise capacity, causing male infertility.

Third, less sperm of

Generally believed that many times the regular number of sperm semen tests were below 20 million / ml as less of sperm. Pregnancy rates will drop significantly, leading to the common cause of male infertility.

Cause: lead to less sperm of the reasons include the following seven aspects.

1, of varicocele of varicocele, so that the local testicular temperature increases, the vasoactive substances increase, thus affecting spermatogenic function. However, the extent of varicocele sperm quality and disproportionate.

2, cryptorchidism cryptorchidism that affect sperm quality important one of the reasons. Unilateral cryptorchid about 60 percent of infertility patients, so if the sperm density, there existed Cryptorchism to early treatment.

3, reproductive tract infections subsidiary gonad of chronic infection, can affect sperm in the laboratory of indicators.

4, autoimmune reproductive immunology research found that men may affect autoimmune fertility, anti-sperm antibodies can affect sperm production and delivery.

5, male endocrine abnormalities normal spermatogenesis dependent on the hypothalamus - pituitary - gonadal axis in the normal function, a part of any of these obstacles will affect spermatogenesis, such as other thyroid and adrenal diseases will also affect gonad function result of fewer sperm .

6, chromosomal abnormalities on chromosome aberrations sperm density, activity rates and patterns have seriously affected.

7, other scrotal temperature is too high, radiation injury, chemical drugs and drug effects may result in fewer sperm.

4. Azoospermia

Azoospermia refers to the injection of semen centrifugal precipitation, the microscopic examination without sperm.

Cause: azoospermia can be divided into two categories: The first category is spermatogenic dysfunction, can not produce sperm, also known as the true azoospermia. The second category is spermatogenic normal, but the vas deferens obstruction, sperm can not be discharged in vitro, also known as obstructive azoospermia.

5, the high rate of abnormal sperm

There are also normal sperm abnormal sperm (Table 25-1), the general percentage of less than 30 per cent, if the percentage of abnormal sperm are 50 percent higher than the deformity known as the high rate of sperm, can lead to infertility.

Cause: a large number of abnormal sperm in the testes sperm abnormalities; certain drugs such as furans can make sperm abnormality rate of increase of varicocele can cause abnormal sperm increased, is typical of the double-headed sperm addition, a number of acute diseases and physical , Mental factors are pathogenic role.

6, Jing of blood

Semen in the blood which is mixed with the blood of the fine. General was pink, red, brown or red with Blood-streaked phlegm. According to the different nature of disease and the number of blood to the naked eye can show blood refined, including blood clots and blood under fine.

Cause: the seminal vesicle and prostate inflammation, tuberculosis, schistosomiasis, stones, damage can lead to blood fine, with the most common Jingnang Yan; some tumors such as the seminal vesicle and prostate cancer, Fu Jing papilloma, can also be benign prostatic hypertrophy Cause blood refined, and some of varicocele blood diseases may also cause blood fine.

7, low sperm activity and death of fine

Pai fine, the sperm should be dynamic in more than 70 percent, if the sperm vitality of less than 50 per cent of abnormal sperm activity known as the lower, also known as the weak of fine. If the sperm is no activity for the death of sperm. Sperm activities of the lower fine and death of male infertility is caused by one of the important reasons.

The activities of the sperm directly reflect the quality of sperm, WHO recommended method, the sperm activity is divided into four: 0 - no, no to the former; one - undesirable activities, the former campaign to weak; two — Activities generally, the middle before the campaign; three - good activities, before the activists.

Cause:

1, long-term abstinence, not long-term sperm ejaculation often high density, dead sperm, poor sperm activity, this situation is normal, so check before semen abstinence 5 ~ 7 d suitable.

2, reproductive infection, reproductive infection to change the seminal elements of zinc, magnesium, citric acid, fructose and reduce the pH increase will affect sperm motility.

3, of varicocele, the testis and epididymis blood circulation obstacles, local temperature increases, the accumulation of toxic substances so that the activities of the lower sperm.
