Having one biochemical pregnancy does not necessarily mean that the patient is infertile. Generally, after one biochemical pregnancy, with appropriate adjustment, it is possible to have a normal pregnancy next time. The causes of biochemical pregnancy result from natural selection, most commonly due to defects in the fertilized egg itself, insufficient function of the ovarian corpus luteum, abnormalities in the endometrium, underdeveloped uterus, or conditions such as uterine fibroids or endometrial tuberculosis. These factors can affect the implantation of the fertilized egg. It is advised to undergo thorough pre-pregnancy checks before attempting to conceive again.
