The detrimental effect of increased endometrial thickness on implantation and pregnancy rates and outcome in an in vitro fertilization program

What Was Tested

This clinical trial paper looks at hCG (human chorionic gonadotropin) in the context of endometriosis.

To determine whether there is a maximal value for endometrial thickness, as measured on the day of hCG administration, above which implantation and pregnancy are unlikely to occur.

Who Took Part

The study group was 623 patients.

The age groups tagged for this paper are adults, women only.

A total of 809 IVF cycles in 623 patients resulting in ET.

How the Study Was Run

A university-based tertiary care center for assisted reproductive technology.

Endometrial thickness was measured by means of transvaginal ultrasound on the day of hCG administration.

Cycles were divided into two groups based on endometrial thickness.

What Was Measured

What This Means in Plain Language

This is a clinical trial of hCG (human chorionic gonadotropin) in 623 patients in people with endometriosis.

With several hundred people or more, it is a fairly large study for this kind of research.

Its findings take up roughly 5 sentences of the abstract and are left out here on purpose; the source paper is the place to read them.

The publication is from 1999 (Fertility and sterility), a journal based in United States.
