For roughly 30% of couples who come in, the cause for not being able to conceive lies with the man. For roughly 20%, the cause lies with both the man and the woman in the relationship. Male fertility disorders usually come down to the insufficient production of agile sperm cells. If you have never conceived naturally, sperm analysis can provide clarity regarding the quality of your sperm. We conduct semen analyses in our specialized laboratory.
The production of sperm cells starts during puberty and takes place in the testicles. This process is regulated by the sex hormone FSH (follicle stimulating hormone), which stimulates the production of millions of sperm cells every day. After roughly ten weeks, the sperm cells move from the testicles to the epididymis for the final stage in their maturation. If the maturation of the sperm cells is disordered or disrupted, either there won’t be enough sperm cells or the sperm cells will not be agile enough. This decreases the odds of the sperm cells reaching the oocyte located in the woman’s fallopian tubes.
During ejaculation, the sperm cells move from the epididymis to the vas deferens and through the urethra, they enter the woman’s vagina. Through the uterus, the sperm cells move to the fallopian tube, where the oocyte is located. In some cases, there are enough agile sperm cells but they may be unable to enter the woman’s body, for example due to a blockage of the vas deferens. This is the cause of reduced male fertility in roughly 4% of cases. A blockage of the vas deferens can be something that you were born with, or it might be the result of an earlier sterilization. Epididymitis (an infection of the epididymis), too, may cause a blockage of the vas deferens.
If you come in to our clinic because you are unable to have children as you wish, a semen analysis is usually one of the first diagnostic actions we take. During one, a sperm sample is examined microscopically in our specialized laboratory as soon as it is obtained (within 60 minutes). The ejaculate is inserted into a special counting cell and analyzed using a microscope. During the examination, we determine the volume of the ejaculate, the number of sperm cells and their agility and shape.
Volume of the ejaculate: usually, this is over 1.5 milliliters
Concentration (number of sperm cells in each milliliter of fluids): usually, there are over 15 million sperm cells in one milliliter
Motility (the sperm cells’ agility):
This is subdivided into several classes:
Usually, over 32% of the sperm cells in the sample should have a higher motility (Class A and/or B)
Morphology (the sperm cells’ shape): Usually, over 4% of the sperm cells in the sample should have a normal shape
pH (acidity): Usually, this is higher than 7.2
Agglutination (clumping of sperm cells): Usually, this doesn’t happen.
MAR test or Immunobead test (tests whether a man produces antibodies against his own sperm): This should be beneath 40%
Vitality (number of live sperm cells): This should be over 75%
If the semen analysis doesn’t meet these criteria, reduced male fertility could be involved in you and your partner’s inability to conceive. If this seems to be the case, a semen analysis will usually be repeated a few weeks down the line. If the analyses repeatedly indicate reduced fertility, we’ll advise you thoroughly regarding fertility treatment options. Our physicians will gladly provide extensive advice regarding this and other subjects.
A disordered sperm cell maturation process can be either temporary or permanent, and it can be caused by either a congenital defect or an illness. The most common causes include:
Regarding our diagnosis protocol: our physicians will take into account all possible causes of a fertility disorder, and they will recommend the necessary treatment.
