Studies say that
15% of couples are not fit for conceiving a child. They are not able to
conceive even after attempting frequent sexual intercourse without any
protection for years. One-third of these couples have the infertility issue in
men.
The reason behind
male infertility is low sperm count, blockages that abort the delivery of sperm
or abnormal sperm function. There can be numerous other reasons behind male
infertility like injuries, illness, chronic health issues and lifestyle
choices.
Unable to produce
sperm or conceive a child is no doubt stressful, but one can avail various male
fertility treatments.
Symptoms of Potential male Infertility.
Symptoms which depend upon the causes of infertility. They can consist:
Problems with erections and ejaculation
Changes in sexual desire
Small, firm testicles
Changes in hair growth
Pain, lump, or swelling in the testicles
Causes of male infertility
Listed below are some of the
major causes of Male Infertility:
●
When the sperm’s passage get obstructed
●
Hormone-related
issues
●
Low sperm count
●
Impotence or other functional problem.
Obstructions causing infertility in men
Sperm is manufactured inside testicles, thereafter it passes through epididymis (a series of small tubes) spending about 2-10 days. In this span, the sperm gets matured and come into vas deferens (a larger tube). The vas deferens channel the sperm into the ejaculatory duct, where it comes in contact with seminal fluid which comes from the prostate gland and the seminal vesicles to form a mixture.
The semen is
forced into the urethra and finally out of the penis due to muscular
contractions during ejaculation. Around one in three cases of infertility in
men is due to absences or blockage of tubes (the vas deferens as well). Injury
or vasectomy can be a reason behind the blockage or absence of tubes.
Problems with sperm causing infertility in men
Genetic factors
are thought to be responsible for the problems with sperm count or its quality.
The sperm problems can also lead to the absence of tiny fragments of the male
chromosome in some men. This may result in:
● Azoospermia (Absent sperm) - when the
sperm is absent in semen. Testicular failure or blocked tubes can lead to this condition.
● Oligospermia (Low sperm count) – the
sperm in the ejaculate is not in a sufficient amount to bring about conception.
● Abnormal shape – healthy sperm looks
like a streamlined tadpole in shape. Sperm with abnormal shape may face
problems while penetrating the egg’s surface.
● Poor motility – a healthy sperm swims
through the woman's reproductive system with the help of its lashing tail.
Sperm having poor motility may swim clumsily or sometimes not at all.
Infertility in men due to Functional problems.
Some of the Functional problems
that can lead to male infertility include:
● Impotence – the inefficiency to
maintain or get an erection needed for sexual intercourse
● Prostatectomy – when the prostate gland
is removed surgically leading to side effects, as well as impotence,
infertility and incontinence.
● Ejaculation issues – retrograde (when
semen doesn’t emerge through the penis and enters the bladder) as well as
immature ejaculation.
● Problems
related to the testicles – due to some infection, injury or chemotherapy
● Antibodies – the sperm activity is
hindered by the antibodies made by man’s immune system, like lowering the
sperm’s capacity to latch onto an egg from his partner.
● Certain disorders – diabetes, multiple
sclerosis as well as other syndromes can lead to problems in erection and ejaculation.
Hormonal problems causing infertility in men
A series of
glands and hormones they release are responsible for regulating the levels of
male sex hormones. Hormone production in the testicles guided by the
hypothalamus is influenced by the pituitary gland in the brain The failure to
manufacture a good amount of the hormone gonadotrophin is relatively an
uncommon reason for male infertility.
Apart from the
mentioned above factors, there are many other medical, environmental, health,
lifestyle and other causes which lead to infertility in men.
