Increased mid luteal serum P4 levels are not associated with a higher CPR in women undergoing COH with IUI. However, a low mid luteal P4 level < or =25 nmol/L may help predict treatment failure.
The present paper reports a single department's retrospective case series of all clomiphene citrate (CC) combined with intrauterine insemination (IUI) treatment cycles for ovulatory infertility performed during 2002. Thirty-eight couples with unexplained, endometriosis, male or unilateral tubal factor infertility had undergone 71 cycles of CC and IUI. The clinical and ongoing cycle pregnancy rates were 20 and 17%, respectively. Seven percent of the clinical pregnancies were multiple pregnancies, with all multiple pregnancies being twin gestations. The current use of CC and IUI is an effective early treatment option in couples with ovulatory infertility presenting to our department.
Background
Higher‐order multiple (HOM) pregnancies are associated with significant maternal and neonatal morbidity, especially consequent to preterm birth. Multi‐fetal pregnancy reduction (MFPR) may be provided, though its benefits in prolonging gestation and improving neonatal outcomes must be weighed against its risks.
Aims
The aim was to compare outcomes of HOM pregnancies where expectant management was chosen (EM) with those where MFPR was provided.
Methods
The method involved a retrospective study of HOM pregnancies referred to a single quaternary hospital between 2007 and 2016. The primary outcome was gestational age. Secondary outcomes included miscarriage, nursery admission, hospital stay, Apgar scores, early fetal loss, stillbirth, neonatal death and composite fetal loss.
Results
Fifty‐seven pregnancies were eligible for inclusion. Median gestation at birth (weeks) was significantly higher for MFPR (35.3 vs 33.1, P < 0.01). Pregnancies after MFPR were less likely to lead to preterm birth (63.2 vs 100.0%, P < 0.001), half as likely to birth before 34 weeks (31.6 vs 60.0%, P = 0.09) but similarly likely to extremely preterm birth (<28 weeks, 8.6 vs 10.5%, P = 0.58). Miscarriage was more likely after MFPR (13.6 vs 0%, P = 0.05). EM neonates were more likely to be admitted to the nursery (P < 0.01) and have longer hospital stay (29.6 vs 20.2 days, P = 0.05); however, they had similar Apgar scores.
Conclusion
Our study demonstrates that MFPR is associated with an increase in gestational age, with a reduction by almost half of births before 34 weeks, but no difference in extremely preterm births; the latter represents the highest risk group. This should be used to guide management counselling for HOM pregnancies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
