The spontaneous LH surge in ovarian hyperstimulation for assisted reproductive technology.

What Was Tested

Researchers studied Chorionic Gonadotropin in this randomized controlled trial publication.

Thirty-seven patients who underwent assisted reproductive technology programme, in vitro fertilisation or embryo transfer and gamete intra-fallopian transfer, were randomised into two groups in order to evaluate frequency of premature spontaneous LH surge when stimulated with different type of hMG.

Why It Was Studied

An hMG (FSH:LH = 1:1) was administered for eighteen patients (group A) and the different highly purified hMG (FSH:LH = 19:1) was administered for nineteen patients (group B).

Blood samples are drawn from day 3 of the cycle until hCG administration, and serum LH level are measured in the frozen samples.

Who Took Part

PubMed tags the participants as women only.

How the Study Was Run

In design terms this was a randomized study.

The participants were allocated by chance, so the Chorionic Gonadotropin group and the comparison group should start out alike.

What Was Measured

Blood samples are drawn from day 3 of the cycle until hCG administration, and serum LH level are measured in the frozen samples.

What This Means in Plain Language

The paper is a randomized study of Chorionic Gonadotropin.

The publication is from 1992 (Annals of the Academy of Medicine, Singapore), a journal based in Singapore.
