With the aggravation of various pollutions, many males have suffered from infertility, which has cast a layer of gloom on the originally happy family. The quality of male sperm also declines, so what is the reason for the decline in male sperm quality?
Cause 1: Obstruction of the vas deferens
In a small percentage of men, the vas deferens are blocked, preventing sperm from entering the semen.
The epididymis are convoluted tubes that store and transport the sperm produced by the testes; the vas deferens are two tubes that are responsible for transporting the sperm that is about to be ejaculated from the epididymis. If these ducts are blocked or damaged, it can prevent sperm from successfully reaching your wife’s eggs.
An infection, injury, birth defect, or vasectomy can cause a blockage of the vas deferens.
1. Possible symptoms: none
2. Possible treatment methods: surgery to repair the blocked part or vas deferens reversal
3. Success rate: After vasectomy reversal, about 80% to 90% of men’s semen contains sperm, and 40% to 50% of couples will successfully conceive within one or two years.
The success rate of conception using standard in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) depends on the specific fertility problem and the age of the wife.
Reason 2: Varicocele
A varicocele is a dilated vein in the scrotum, similar to varicose veins in other parts of the body, which raises the temperature in the testicles and affects sperm production.
1. Possible symptoms: None. This problem is usually discovered during a physical exam.
2. Possible treatment methods: surgical treatment of varicose veins; in vitro fertilization (IVF).
3. Success rate: There is still no conclusion in the medical field about the impact of varicocele on male fertility and sperm quality. Not all men with varicocele have sperm problems. Although surgery can improve the quantity and quality of sperm, it does not necessarily increase the chances of conception. This issue remains to be further studied. It is recommended to consult a physician for the latest evidence-based treatment options.
Reason 3: Abnormal sperm
If you have low sperm count, no sperm, low sperm motility (ability to swim), or deformed sperm, your sperm may not be able to fertilize your wife’s eggs naturally.
1. Possible symptoms: None.
2. Possible treatment methods: intrauterine insemination (IUI) using donated sperm or your own sperm (of course, the premise of using your own sperm is that the sperm is not very abnormal in terms of quantity, shape and vitality); Intracytoplasmic sperm injection (ICSI); or the wife’s use of fertility drugs to increase the number of ovulations.
3. Success rate: If intrauterine insemination (IUI) is combined with the use of reproductive drugs, and the wife’s fallopian tubes and the sperm used are healthy , the success rate of each cycle is about 15%. If the wife is under 35 years old, the success rate of intracytoplasmic sperm injection (ICSI) is about 29% per cycle.
Reason 4: Sperm Allergy
Your body may produce antibodies that kill its own sperm. This condition is more common after a vasectomy, testicular torsion (a twisting of the testicle in the scrotum), infection, or after an accident. It is estimated that about 3% of male infertility cases are caused by sperm allergies.
1. Possible symptoms: None.
2. Possible treatment methods: intrauterine insemination (IUI) or intracytoplasmic sperm injection (ICSI). It is also treated with steroids such as prednisone.
3. Success rate: If intrauterine insemination (IUI) is combined with the use of reproductive drugs to promote ovulation, and the wife’s fallopian tubes and the sperm used are healthy, the success rate is about 15% per cycle. If the wife is under 35 years old, the success rate of intracytoplasmic sperm injection (ICSI) is about 29% per cycle. Many doctors would not recommend steroids because of their unproven efficacy in treating sperm allergies and the potential for serious side effects.
Reason 5: Ejaculation disorders
Ejaculation disorders include complete absence of ejaculation and retrograde ejaculation. Retrograde ejaculation is when sperm is not ejaculated or is ejaculated retrogradely into the bladder. Causes of ejaculation problems include conditions such as diabetes or multiple sclerosis , spinal cord injuries, injuries from surgery, or psychological problems.
1. Possible symptoms: ejaculation disorder, including no ejaculation or a small amount of ejaculation.
2. Possible treatments: Drugs to close the catheter leading to the bladder to prevent sperm from going the wrong way; drugs to treat psychological disorders that inhibit erections or ejaculation; electronic or vibratory stimulation to assist ejaculation, or surgery for assisted conception Sperm extraction.
3. Success rate: The pregnancy success rate of retrograde ejaculation after drug treatment is 56%-79%. The success rate of assisted conception is 16%-100%, depending on what the specific ejaculation disorder is and the sperm retrieval method used.
Generally speaking, there are the above five reasons for male infertility. If the family is infertile within two years of marriage, the couple can go to a regular hospital for a comprehensive examination.
So how should male infertility be prevented? See a presentation from an infertility specialist.
1. Do not take drugs:
Men who take drugs can reduce the level of testosterone in the blood, weaken their reproductive ability, incapable of ejaculation, and thus infertility. For example, the sexual desire suppression of heroin addicts reaches 100%, and that of methadone addicts reaches 96.5%.
2. Quit smoking and limit alcohol:
Smoking and alcoholism are the enemies of sperm. Some men’s bodies are quite sensitive to the toxins in cigarettes, and the nicotine in cigarettes can kill sperm. Alcoholism will not only reduce the function of gonads, but also cause chromosomal abnormalities in sperm, which will lead to fetal malformation or dysplasia.
3. Avoid radiation exposure and electromagnetic radiation:
Long-term electromagnetic radiation and a large amount of radiation exposure can also cause sperm chromosomal aberrations.
4. Men in childbearing period do not abuse drugs at will:
Regular use of sedatives, antitumor drugs, marylan in chemical drugs, hormone drugs, etc. will cause sperm growth disorders, sperm chromosome damage and breakage.
5. Sexual life should be restrained:
If sexual intercourse is too frequent and excessive indulgence, it may not only lead to impotence , but also reduce the amount of sperm contained in each ejaculation.
6. Avoid prolonged hot baths:
The process of sperm growth requires low temperature, otherwise the sperm will die. If a man has a hobby of taking hot baths, it may reduce the number of sperm and even lead to infertility.
Regarding the prevention of male infertility, pre-marital inspection should be done well. Through the inspection, early detection of abnormalities can avoid the pain after marriage. In the life of husband and wife, we must cooperate and understand each other, otherwise impotence, premature ejaculation or abnormal ejaculation will easily occur. sexual dysfunction .
