Does being overweight affect my sperm?
Overweight men may have more estrogen hormones (the female hormone) and less testosterone (the male hormone), leading to a decrease in sperm production and lower fertility.
How does my body produce sperm?
Every 72 days, new sperm is produced. This process is cyclical and takes place continually in different parts of the testicles, thus always assuring the presence of spermatozoids in the ejaculate of healthy men.
How can I know if my sperm is good?
The parameters for seminal quality are determined by the WHO (World Health Organization). In the last few years, the seminal quality in all men all around the world has decreased. ProcreaTec recommends a sperm analysis analyze the male factor. With these results, a diagnosis and prognosis of the probability of pregnancy can be made.
What is measured in a Sperm Analysis?
In a sperm analysis the morphology, motility and concentration of spermatozoa per milliliter of semen is analyzed.
- Normal sperm morphology means the head should be round and smooth, the tail should be three times the length of the head and joined correctly to it.
- Motility is defined as the speed with which the spermatozoon advances (micrometers per second) in a straight line.
- Sperm concentration should be over 10 million/ml.
All these parameters need to be within the limits established by the WHO in 2010.
How do you define a healthy spermatozoon?
The spermatozoon is the male gamete that defines the genetic gender of the future baby.
It is a germinal cell composed of a flagellum (a tail), an intermediate piece (the neck) and a head. An anomaly in any of these parts implies a decrease in the probability that this spermatozoon will be able to fertilize an egg.
What is oligozoospermia?
Oligozoospermia is when the concentration of spermatozoa per milliliter in the ejaculate is less than the parameters of normality set by the WHO. Currently this condition represents a concentration of less than 15 million per milliliter.
The quantity of spermatozoa in the ejaculate of the man is a fluctuating parameter and can be affected by medication, stress or illness such as an infection. So if a serious alteration in sperm concentration is detected, it is very important to do another test at a later date to make sure that the results are correct.
What is azoospermia?
Azoospermia is the absence of spermatozoa in the ejaculate. If no sperm is found in the ejaculate it is imperative to repeat the sperm analysis to be able to confirm the diagnosis.
Azoospermia can have two origins. Secretory azoospermia is caused by an alteration in the testicle that impedes the formation of spermatozoids. Obstructive azoospermia is caused by the obstruction of the ducts through which the sperm travels.
Treatment depends on the type of azoospermia and goes from a testicular biopsy to obtain sperm directly from the testicle (when obstructive azoospermia is diagnosed) to the use of donor semen (in the case of secretory azoospermia).
What is astenozoospermia?
Astenozoospermia is when spermatozoa move slower than normal. Currently the WHO considers normal a 32% progressive motility in the ejaculate.
Alterations in motility may be caused by previous medical treatments and by unhealthy habits.
There are treatments to improve sperm motility such as antioxidant vitamins.
What is teratozoospermia?
Teratozoospermia when the percentage of abnormal spermatozoa in the ejaculate is higher than 4%, the parameter considered normal set by the WHO.
When teratozoospermia is found more testing is usually needed to determine if there is a genetic or hormonal cause.
