Objective:
To identify and estimate the importance of risk factors on pregnancy loss until the end of the second trimester after clinical pregnancy was achieved by either in vitro fertilisation (IVF) or intra-cytoplasmic sperm injection (ICSI).
Study Design:
Retrospective cohort study including 588 cycles with fresh embryo transfers and 150 cycles with frozen-thawed embryo transfers using logistic regression.
Results:
The rate of miscarriages subsequent to a fresh embryo transfer was significantly increased by a diagnosis of endometriosis (p=0.02), as well as significantly influenced by the age of the female patient at the time of oocyte retrieval (p<0.01) and the serum level of testosterone (p=0.02). The time between freezing and thawing of the pronuclear stages for a frozen-thawed embryo transfer revealed a trend to a higher rate of miscarriages (p=0.06).
Conclusion:
Endometriosis significantly decreases the chance of having a baby even with IVF or ICSI.
