Unexplained infertility makes up approximately 30% of diagnosis results that are given to women who have failed to become pregnant. This can be increasingly frustrating for all people involved and it is a common cause of anxiety for the women who are trying to successfully become pregnant. This short article will cover the possible causes of unexplained infertility and include a brief mention of the treatments that are available.
As the direct cause of the infertility is not known in this situation and as suggested by the name, we must instead consider plausible factors for the result:
- Immune System Instability – When working as it should, the immune system acts as the body’s line of defence that fights off disease and infection, maintaining healthy body cells. However sometimes the immune system can be defective and instead cause damage to body cells that are healthy. If gametes (sex cells, such as the egg and sperm) are damaged by the immune system, they cannot lead to a successful pregnancy.
- Unhealthy Sperm – For a successful pregnancy to occur, the egg must be fertilized by the penetration of the sperm, through the shell. If the sperm are not strong or healthy enough to complete this task, an embryo cannot grow.
- Factors of Emotion – Each process of the body is executed by the brain and so the psychological well-being of both partners during a pregnancy should be considered seriously. It can have knock on effects to the immune system and coping mechanisms for anxiety and stress – all of which are symptoms that can be caused in the build-up and duration of a pregnancy.
- Egg Abnormalities – As is the case with all biological processes, imperfections can occur and certain eggs may not be strong enough or healthy enough to be fertilized successfully.
Despite the direct cause of the infertility being unknown, there are a number of treatments available that can increase the success of pregnancy:
- IVF (In-Vitro Fertilization) Treatment – If the development of embryos and the initial fertilization of the egg or health of the ovaries is in question. This process can be carried out in a laboratory and the fertilized embryos are then implanted back into the uterus of the mother for the remainder of the pregnancy.
- Use of medication – Fertility drugs can be used which stimulate the production of eggs by the body and therefore increase the success rate of a pregnancy occurring.
IUI (Intrauterine Insemination) – This process involves the placing of sperm inside the uterus, increasing the proportion of sperm that reach the fallopian tubes and therefore raising the chances of successful fertilization.
