A nomogram to predict the probability of live birth after clomiphene citrate induction of ovulation in normogonadotropic oligoamenorrheic infertility
Open accessAbstract
Objective To establish whether initial screening characteristics of normogonadotropic anovulatory infertile women can aid in predicting live birth after induction of ovulation with clomiphene citrate (CC).Design Prospective longitudinal single-center study.Setting Specialist academic fertility unit.Patient(s) Two hundred fifty-nine couples with a history of infertility, oligoamenorrhea, and normal follicle-stimulating hormone (FSH) concentrations who have not been previously treated with any ovulation-induction medication.Intervention(s) 50, 100, or 150 mg of oral CC per day, for 5 subsequent days per cycle.Main outcome measure(s) Conception leading to live birth after CC administration.Result(s) After receiving CC, 98 (38%) women conceived, leading to live birth. The cumulative live birth rate within 12 months was 42% for the total study population and 56% for the ovulatory women who had received CC. Factors predicting the chances for live birth included free androgen index (testosterone/sex hormone-binding globulin ratio), body mass index, cycle history (oligomenorrhea versus amenorrhea), and the woman's age.Conclusion(s) It is possible to predict the individual chances of live birth after CC administration using two distinct prediction models combined in a nomogram. Applying this nomogram in the clinic may be a step forward in optimizing the decision-making process in the treatment of normogonadotropic anovulatory infertility. Alternative first line of treatment options could be considered for some women who have limited chances for success.

“The FAI, but also BMI, cycle history (oligomenorrhoea or amenorrhoea) and mean ovarian volume, were found to be criteria that influence the ovarian response to stimulation with clomiphene citrate medication (Imani et al., 2002;Balen et al., 2016).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
