Infertility is defined as the inability to conceive after 12 months.

If we statistically decrease the monthly rate over a year, that is, 12 months, we will see a result with a probability of conception of about 90-95% per year. After that, and if a couple has not achieved the desired result, we consider that one year is the appropriate time to seek the help of an expert.



The problem of infertility lately seems to be increasing, mainly due to social and environmental factors, nutritional conditions and lifestyle changes. However, it is a timeless and relatively stable problem. Since the 19th century it seems that 1 in 6-7 couples experiences difficulty or complete inability to conceive and reproduce. The causes are divided into three major categories:

  • Male infertility problems

They account for 30-40% of the cases and result from problems in sperm count, motility and morphology, anatomical causes, and problems with sexual function and ejaculation.

  • Female infertility problems

They account for 30-40% of the cases and come from problems with ovulation, ovarian quality, disorders of the cervical mucus and cervical diseases, uterine diseases such as fibroids, polyps and congenital uterine disorders, problems with fallopian tubes such as infections, adhesions and obstructions, endometriosis and advanced age.

  • Unexplained infertility

It accounts for about 25-30% of infertile couples. Although the term “unexplained” can cause confusion and reasonable queries for a couple, it essentially refers to factors of infertility that science is not yet aware of and will likely be resolved in the future.
