What This Study Did, in Plain Language
What Was Tested
The paper reports a study of hCG (human chorionic gonadotropin) and Triptorelin in the context of pcos, published as a randomized controlled trial.
To evaluate whether the number of oocytes retrieved is different by using the two GnRH antagonist protocols in Chinese women with predicted high ovarian response except PCOS.
Why It Was Studied
No previous study directly compares the fixed day-5 initiation versus the flexible initiation of GnRH antagonist administration in IVF/ICSI for those patients who are predicted as high ovarian responders without PCOS.
NCT02635607 posted on December 16, 2015 in clinicaltrials.gov.
Who Took Part
The abstract describes 201 women taking part.
PubMed indexes the participants as young adults and adults, women only.
A randomized controlled trial of 201 infertile women with predicted high ovarian response except PCOS undergoing in vitro fertilization.
Patient monitoring was initiated on day 3 of stimulation in flexible group.
How the Study Was Run
In design terms this was a randomized study.
Random assignment meant chance, not the researchers, decided who got hCG (human chorionic gonadotropin) and who got the comparison, which limits bias.
Ovary stimulation was performed using recombinant FSH and GnRH antagonists.
What Was Measured
The subject headings attached to it are Chorionic Gonadotropin, Fertilization in Vitro, Follicle Stimulating Hormone, Human, Gonadotropin-Releasing Hormone, Infertility, Female, Ovary and Ovulation Induction.
The authors tagged it with the keywords Fixed protocol, Flexible protocol, Gonadotropin-releasing hormone antagonists, In vitro fertilization and Number of oocytes retrieved.
What This Means in Plain Language
The paper is a randomized study of hCG (human chorionic gonadotropin) and Triptorelin in 201 women in people with pcos.

Our Notes on the Compounds
hCG (human chorionic gonadotropin): An LH analog that drives Leydig-cell testosterone production.
Triptorelin: A 10-amino-acid GnRH analog (Trelstar, Decapeptyl, Triptodur) used in prostate cancer, early puberty and fertility protocols.
