Testicular tissue freezing is the
extraction and subsequent cryopreservation of this tissue to try to preserve
the fertility of a patient who is going to undergo gonadotoxic treatment.
One of the medical cancer treatments’ side
effects (chemotherapy and radiotherapy) is the fertility decrease in patients
who suffer from it. Fortunately, there are male fertility preservation methods
with high chances of reproductive […]
Ejaculation disorders are one of the most common sexual disorders in the male population. These are common in urology consultations and a possible cause of infertility.
What
is anejaculation?
Anejaculation
is defined as a type of ejaculatory dysfunction that consists in the male’s
inability to ejaculate during intercourse, preventing the exit of seminal fluid
into the female genital tract. Its incidence […]
Infertility affects about 15 % of couples seeking pregnancy. Approximately 50 % of these cases are attributable to the male couple. One of the potential causes traditionally described in the literature has been the presence of bacteria in the semen.
Is the presence of
bacteria in the semen always pathological?
Not
necessarily. The fact of presence of bacteria in […]
Infertility is described by the World Health Organization (WHO) as “a disease of the reproductive system defined by the inability to achieve a clinical pregnancy after 12 months or more of regular unprotected sex.” Therefore, male infertility refers to infertility originating in the male (20% as a single factor and up to 50% as a […]
Spermatogenesis
is the process of the sperm formation, which are male gametes. It takes place
in the testicular seminiferous tubules with an approximate duration of 62 to 75
days in the human species.
Sperm formation
begins around day 24 of embryonic development in the yolk sac, producing about
100 germ cells that migrate to the buds of the genital organs. Around […]
The World Health Organization (WHO) indicates that a man has hypospermia when the semen sample he produces when he ejaculates is below 1.5 mL. A semen analysis needs to be performed in order to obtain a diagnosis. This test measures different semen parameters such as the volume of the ejaculate, the number of spermatozoa, sperm mobility and so on.
In order […]
A hydrocele is the accumulation of fluid in the
testicular covers (in one or both testicles) causing an almost permanent swelling
of the scrotum.
Is not rare in newborns, but they occur more
frequently in adults. In newborns, it disappears in many cases within months of
birth. In adults, in many cases, the cause is not recognized, but in other,
there […]

It is caused by the mumps virus and typically affects children and teenagers, although it may also cause infections in sensitive adults. In general, the disease […]
Varicocele is the swelling of
the veins that drains the blood from the testicles. Incidence in general population is considered to be between 4,4 and 22,6 %. This incidence is higher in males with infertility (30 –
40%) and it’s the most frequent alteration found in these cases.
Its
symptoms are varied:
Testicle veins swelling and twisting.Pain and discomfort […]
Azoospermia is defined as the absence of sperm in the ejaculate, which is generally classified as either obstructive or secretory.
Obstructive azoospermia
In obstructive azoospermia, the sperm cells cannot complete their journey from the testicle to the urethra through the seminal tract; however, the sperm cells are produced in the testicle (spermatogenesis).
There are several causes […]
