Medroxyprogesterone Acetate versus Gonadotropin-Releasing Hormone Antagonist for the Prevention of Premature Luteinizing Hormone Surge in hyper-responder women undergoing controlled ovarian stimulation for IVF/ICSI Cycles.
Trial report in JBRA assisted reproduction, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo compare the effect of Medroxyprogesterone acetate versus Gonadotropin releasing hormone antagonist for the prevention of premature luteinizing hormone (LH) surge in infertile hyper-responder women undergoing controlled ovarian stimulation for in vitro fertilization (IVF) /intracytoplasmic sperm injection (ICSI) cycles.
methodsOne hundred infertile hyper-responder women who were candidate for IVF/ICSI were randomly assigned into two groups. Group 1 was given 20 mg Medroxyprogesterone acetate from day 1 of the menstrual cycle till trigger day. Group 2 was given GnRH antagonist (injection Cetrorelix 0.25 mg s/c) from the day when the leading follicle reached 14 mm until the day of trigger for the prevention of premature LH surge (flexible protocol). We measured LH serum levels on day 1, day 7 of cycle and on trigger day. The primary outcome measured was the incidence of premature LH surge. Other outcome measures were total number of mature follicles on trigger day, total number of mature oocytes retrieved and number of good quality day-3 embryos.
resultsThere was no premature luteinizing hormone surge in both groups of our study. The mean number of follicles on trigger day, mean number of M2 oocytes retrieved and mean number of good quality day-3 embryos were comparable in both the groups, with no statistically significant difference.
conclusionsThe results of this study stated that MPA can be an effective alternative to GnRH antagonist for the prevention of premature LH surge in hyper-responder women undergoing COS for IVF. It is easy to use, widely available and cost-effective. It may establish a new regimen of ovarian stimulation using MPA as an oral alternative to GnRH antagonist treatment in hyper-responders.
