Evaluation of endocrine testing of Leydig cell function using extractive and recombinant human chorionic gonadotropin and different doses of recombinant human LH in normal men

What Was Tested

Researchers studied hCG (human chorionic gonadotropin) in this randomized controlled trial publication.

The functional testing of endocrine testis uses extractive human chorionic gonadotropin (ehCG).

Recombinant human hCG (rhCG), avoiding any contamination, should replace ehCG.

Who Took Part

The age groups tagged for this paper are teenagers and adults, men only.

The study was conducted in normal men.

How the Study Was Run

In design terms this was a randomized, single-blind and placebo-controlled study.

Because people in this hCG (human chorionic gonadotropin) study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

Only one side, usually the participants, was kept unaware of whether hCG (human chorionic gonadotropin) was given.

The comparison arm used a placebo, so changes seen with hCG (human chorionic gonadotropin) could be set against what happens without it.

LH, testosterone, and estradiol plasma levels were measured after the injection of either rhLH or placebo.

What Was Measured

The functional testing of endocrine testis uses extractive human chorionic gonadotropin (ehCG).

What This Means in Plain Language

The paper is a randomized, single-blind and placebo-controlled study of hCG (human chorionic gonadotropin).

Its findings take up roughly 8 sentences of the abstract and are left out here on purpose; the source paper is the place to read them.

The publication is from 2008 (European journal of endocrinology), a journal based in England.
