Research published in the Canadian Medical Association Journal
has identified a small but significant increase in the risk of congenital anomalies, commonly known as birth defects, for infants born to individuals with endometriosis.
The findings suggest that while there is a modest increase in the relative risk of these anomalies, the absolute increase in risk remains small.
Medical experts emphasizing the results noted that the vast majority of people with endometriosis will have babies born without congenital anomalies.
Endometriosis is a medical condition where cells similar to the lining of the uterus, or endometrium, grow outside of the uterus, frequently involving the pelvic tissue.
The research examined the relationship between the condition and infant health, specifically looking at whether the increased risk was driven by the condition itself or by the fertility treatments often used to achieve pregnancy when endometriosis is present.
Data indicates that approximately 11% of the increased relative risk was explained by the use of in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI).
Other fertility-related factors did not appear to mediate the relationship between endometriosis and the occurrence of congenital anomalies. These factors included:
- Subfertility
- Ovulation induction
- Intrauterine insemination
The distinction between relative and absolute risk is critical for understanding the clinical impact of the study. Relative risk compares the risk of an event in one group to the risk in another, whereas absolute risk refers to the actual probability of the event occurring.
while the relative risk is higher for those with endometriosis, the overall likelihood of a baby being born with a congenital anomaly remains low.
The study adds to the ongoing medical understanding of how endometriosis affects reproductive health and neonatal outcomes, highlighting a link that exists independently of many common fertility interventions.
