Objective:
To report preterm birth and small for gestational age (SGA) rates from assisted reproduction technologies (ART) patients with ovarian endometriomata compared with control groups.
Design:
Retrospective cohort study.
Setting:
Tertiary university affiliated ART center and Perinatal Data Collection Unit (PDCU).
Patient(S):
Every woman who had an ART singleton baby born between 1991 and 2004 had her database record assessed (N = 4382). Control groups included 1201 singleton babies from ART patients without endometriosis and 2400 randomly selected women from the PDCU database of 850,000 births.
Intervention(S):
There were 95 singleton ART babies from patients with ovarian endometriomata and 535 ART singleton babies from patients who had endometriosis but no ovarian endometriomata.
Main Outcome Measure(S):
Preterm birth rates and SGA birth rates.
Result(S):
Preterm birth rate increased only in the ovarian endometriomata group when compared with community birth records (n = 850,000). Furthermore, ART patients with ovarian endometriomata had a statistically significantly increased likelihood of having a SGA baby when compared with other forms of endometriosis.
Conclusion(S):
Rates of preterm birth and SGA babies doubled in infertility patients with ovarian endometriomata who required ART.
