All infertility has a cause.
At Equipo Juana Crespo, we believe that all cases of unknown infertility have an underlying cause.
Therefore, couples experiencing this situation should know that their chances of pregnancy are not lower than those of a couple with infertility due to an already identified cause.
The challenge in this case is to identify the cause that is preventing fertility to find the appropriate treatment. This is relative sterility, as the possibility of finding an adequate response depends to a large extent on how the diagnoses are made, the specialists involved, and the clinic where they are performed.
Remember that the female and male reproductive apparatus is a system where all the organs and participants have specific functions, but they must also be perfectly synchronised for reproduction to take place.
The most common reasons for unexplained infertility are related to multifactorial causes, i.e., causes where several organs are affected to a greater or lesser extent, and which are difficult to diagnose with conventional or basic fertility tests. Poor egg or sperm quality due to genetic causes, implantation problems due to poor endometrial receptivity, and structural problems in the uterine cavity are other potential causes.
The most common causes for unexplained infertility are related to egg and sperm quality. Poor quality eggs and/or sperm with genetic alterations can lead to difficulties in fertilization and/or the formation of an abnormal or suboptimal quality embryo to result in a live new-born. Implantation problems due to poor endometrial receptivity or structural problems of the uterine cavity also account for a significant number of unexplained infertility cases.
