Common causes of male infertility, reasons for the rising incidence in recent years, and key points of physical examination.
1.4.9. Common causes of male infertility (some useful information)
There are many causes of male infertility, which can be broadly categorized as follows:
(1) Reproductive system infections and diseases:
① Acute infection, acute orchitis, seminal vesiculitis, urethritis
Inflammation, prostatitis, and other conditions can all affect fertility, causing problems with sperm quality and transport.
② Chronic infections, such as tuberculosis, gonorrhea, and syphilis, can impair sperm production.
③ Reproductive organ diseases such as varicocele-related infertility.
(2) Sexual dysfunction, erectile dysfunction, anejaculation
In cases of premature ejaculation, such as retrograde ejaculation, the inability of sperm to enter the vagina is the most obvious cause of male infertility.
(3) Sperm problems, azoospermia, oligospermia, spermatorrhea
Low sperm motility, azoospermia, and semen liquefaction problems are all major causes of infertility.
Generally, when the number of sperm in 1 ml of semen is less than 20 million, the fertilization rate will be significantly lower.
If the risk is low, then there's no way to get pregnant.
(4) Abnormal development of reproductive organs:
① Congenital penile hypoplasia, resulting in no ejaculation of semen.
② Congenital urethral abnormalities, such as stenosis, prevent sperm from entering the urethra.
It can enter the vagina and cause infertility.
③ Abnormal testicular development, ectopic testes, etc., can reduce sperm quality and prevent conception.
(5) Some bad lifestyle habits, etc.

It affects male reproductive function. Some unhealthy lifestyle habits, such as
Smoking, drug use, alcoholism, sexually transmitted diseases, etc., lead to the body
Internal environment disorder, damage to gonads and reproductive tract, ultimately leading to
Male infertility. As these problems become increasingly prominent, the number of people suffering from male infertility will further increase.
[1.5.1. What physical examinations should be performed on male infertility patients during their consultation?]
When male infertility patients seek medical attention, they should undergo a general or local examination.
The purpose of the investigation is to identify the cause of infertility and treat it promptly.
The full physical examination includes measurements of height, weight, and blood pressure.
And observation of male secondary sexual characteristics, such as body shape and hair distribution.
Clothing (focusing on beard, armpit hair, and pubic hair), presence or absence of breasts in women.
Personality traits, presence or absence of olfactory abnormalities. Further examination of various systems is also necessary.
Check carefully to identify any abnormalities in the endocrine, circulatory, or respiratory systems.
Abnormalities in the respiratory, digestive, and nervous systems. Anything related to life...

The patient can stand or lie flat while the doctor examines for any abnormalities in the reproductive organs.

Morphology, presence or absence of nodules or abnormalities in the epididymis and vas deferens, presence or absence of sperm.
Varicose veins, presence or absence of hydrocele, etc. Anal examination may be necessary.
A digital rectal examination is performed to examine the prostate and seminal vesicles. The penis should also be examined for any abnormalities.
No deformities, phimosis, induration, or abnormalities at the urethral meatus.
The above examinations can reveal some clues to diseases, allowing for further laboratory testing.
1.5.2. What laboratory tests should be performed on male infertility patients during their consultation?
Testicular biopsy is an important test for male infertility.
The method involves observing the testis via biopsy, which allows for direct estimation of the testis's condition.
The degree of spermatogenic function and spermatogenic disorders, as well as the synthesis of spermatogenic substances in the testes.
The ability of steroid hormones to assess fertility and provide a visual assessment
Data is also an important basis for the choice of treatment and the judgment of prognosis.
Testicular biopsy can measure testicular volume and serum follicle-stimulating hormone (FSH).
Unexplained azoospermia in patients with normal sperm count
It can be used in patients suspected of having testicular tumors.
For generalized Sertoli cell-only syndrome or seminiferous tubule transparency
In patients with similar lesions, the lesions are not easily detected, and their serum FSH levels are high.
The levels are elevated, so a testicular biopsy is not necessary.
Semen analysis is an important method for assessing male fertility.
This is a mandatory test for male infertility. Because male fertility...
The power is primarily manifested in the function of sperm. The functions of sperm and egg...
A healthy egg and normal reproductive structure are essential for fertility, ensuring the union of sperm and egg and fertilization.
The biological essence of semen. The main cellular component of semen is sperm.
Seminal plasma, on the other hand, has protective, nourishing, and sperm-transporting functions.
Used. Semen analysis includes semen volume, sperm motility,
Sperm density, sperm morphology, etc., can be used to evaluate sperm quality.

It should be noted that for male infertility due to semen abnormalities...
Relevant systemic examinations should be performed to identify the cause of the semen abnormality.
Therefore, while taking medication to improve semen abnormalities, treatment should also be administered.
