When a
couple fails to have a child after trying for at least a year, which is the
definition of infertility, fertility problems in which there is a participation
of men corresponding to 50% of cases. The important nuance is that 20% is the
exclusive responsibility of the man, while the other 30% is due to a combination
of factors related to both partners.
20% of cases
of infertility of the couple are due exclusively to man
Although
approximately 40% of cases do not get to determine the cause of male
infertility, it depends on the quality of semen: number, motility, morphology
and vitality of sperm and semen PH. Hence when a couple goes to a fertility
clinic in order to get pregnant is one made seminogram the man to determine
these parameters.
Possible
causes of the loss of semen quality and, as a result of male infertility are
very diverse:
premature
ejaculation.
Retrograde
ejaculation (semen goes into the bladder instead of out through the penis) may
be due to poor closure of the bladder neck, to uncontrolled diabetes, surgery
performed to treat benign prostatic hyperplasia or testicular cancer.
Anejaculation:
is the absence of ejaculation, which can be caused by a spinal cord injury,
diabetes uncontrolled long evolution, surgery practiced in the genital area or
retroperitoneal, or prolonged use of certain drugs, among which antipsychotics
, antidepressants and antihypertensives or causes mentioned for retrograde
ejaculation; It can also occur in patients with poorly controlled diabetes
years of evolution, may be the result of surgery of the genital region and
retroperitoneal, or may be due to the consumption of certain antidepressants,
antipsychotics and antihypertensive drugs.
Drugs and
toxic substances are many drugs that affect sperm production and therefore, the
quality of semen. Particularly noteworthy androgenic steroids (anabilizantes),
thus block the production of testosterone and sperm therefore, being able to
reach a azoospermia (absence of sperm). Drug and snuff can also affect the
count and sperm morphology. Finally, continued exposure to certain toxic
substances (lead, manganese, cadmium, etc) can cause a situation of male
infertility.
Hormonal
disorders: excessive production of prolactin (hyperprolactinemia), the isolated
testosterone deficiency, hypothyroidism, congenital adrenal hyperplasia, etc.
They are some of the hormonal changes that can cause male infertility.
Chromosomal
anomalies account for 21% of cases of azoospermia.
Urogenital
infections: is not very common, but these infections can cause seminal
abnormalities.
Cryptorchidism:
occurs when one or both testicles have not descended into the scrotum and kept
inside the abdomen. This situation, which can be corrected surgically reduces
sperm production.
Varicocele:
is caused by the appearance of varicose veins in the testicle, causing an
increase in scrotal temperature negatively affects semen quality. Treatment is
surgical.
