Single-nucleotide polymorphisms in the lysyl oxidase-like protein 4 and complement component 3 genes are associated with increased risk for endometriosis and endometriosis-associated infertility.

This study was conducted to assess genetic associations with endometriosis in a Puerto Rican population. Statistically significant differences in the allelic frequencies and genotype distribution of genetic variants in lysyl oxidase-like protein 4 (LOXL4) and complement component 3 (C3) were documented in patients with endometriosis-associated infertility versus controls, and in patients with endometriosis versus controls, respectively. In women who have the risk genotype at both single-nucleotide polymorphisms, the estimated risk for endometriosis nearly doubled.

Patients' report on how endometriosis affects health, work, and daily life.

The objective of this study was to assess the burden of endometriosis by obtaining patient-reported outcome data describing the experience of living with this disease. Survey data from 107 women with self-reported, surgically diagnosed endometriosis showed that living with this disease may be characterized by physical limitations that disrupt health, work, and daily life.

Self-reported prevalence of endometriosis and its symptoms among Puerto Rican women.

Objective: To determine the prevalence of endometriosis and its symptoms in a Puerto Rican cohort, and to describe the menstrual, obstetric, and clinical profiles of the women.

Methods: A self-administered questionnaire was given to 1285 Puerto Rican women. Categorical variables were compared using chi2 analysis or Fisher exact test.
