AI-generated summary by gemini-2.5-flash-lite+body, 2026-06-14

This case-control study found an AMH gene polymorphism associated with infertility in endometriosis, but not polymorphisms in the GDF-9 or AMHR2 genes.

This case-control study examined whether polymorphisms in the GDF-9 gene, AMH gene, and AMHR2 gene are associated with endometriosis-associated infertility, enrolling 74 infertile women with endometriosis and 70 fertile control women undergoing tubal ligation. Genotypes for GDF-9 were determined by direct sequencing, while AMH and AMHR2 SNPs were assessed by TaqMan Allelic Discrimination, with age and mean FSH levels reported as similar between groups. The GDF-9 polymorphisms and an AMHR2 polymorphism showed no statistically significant differences between infertile and fertile groups, whereas an AMH gene polymorphism was significantly associated with infertility in the setting of endometriosis. This paper is centrally about endometriosis — it tests AMH, AMHR2, and GDF-9 gene polymorphisms as risk factors for endometriosis-associated infertility.

Abstract

PurposeThe purpose of this paper is to determine whether there is a correlation between polymorphisms in the growth differentiation factor-9 (GDF-9) gene and anti-Müllerian hormone (AMH) gene and its receptor, AMHR2, and endometriosis-associated infertility.MethodsThis is a case-control study to evaluate whether there is a correlation between polymorphisms in the GDF-9 gene (SNPs determined by direct sequencing), AMH gene, AMHR2 (both SNPs determined by genotyping using TaqMan Allelic Discrimination), and endometriosis-associated infertility. The study included 74 infertile women with endometriosis and 70 fertile women (tubal ligation) as a control group.ResultsPatient age and the mean FSH levels were similar between the infertile with endometriosis and fertile without endometriosis groups. The frequency of genotypes between the groups for GDF-9 gene polymorphisms did not show statistical significance, nor did the AMHR2 gene polymorphism. However, the AMH gene polymorphism did show statistical significance, relating the polymorphic allele with infertility in endometriosis.ConclusionsWe demonstrate that an SNP in the AMH gene is associated with infertility in endometriosis, whereas several SNPs in the GDF-9 gene and the - 482A G SNP in the AMHR2 gene were found to be unrelated.

Abstract

Purpose The purpose of this paper is to determine whether there is a correlation between polymorphisms in the growth differentiation factor-9 (GDF-9) gene and anti-Müllerian hormone (AMH) gene and its receptor, AMHR2, and endometriosis-associated infertility.

Methods

This is a case-control study to evaluate whether there is a correlation between polymorphisms in the GDF-9 gene (SNPs determined by direct sequencing), AMH gene, AMHR2 (both SNPs determined by genotyping using TaqMan Allelic Discrimination), and endometriosis-associated infertility. The study included 74 infertile women with endometriosis and 70 fertile women (tubal ligation) as a control group.

Results

Patient age and the mean FSH levels were similar between the infertile with endometriosis and fertile without endometriosis groups. The frequency of genotypes between the groups for GDF-9 gene polymorphisms did not show statistical significance, nor did the AMHR2 gene polymorphism. However, the AMH gene polymorphism did show statistical significance, relating the polymorphic allele with infertility in endometriosis.

Conclusions

We demonstrate that an SNP in the AMH gene is associated with infertility in endometriosis, whereas several SNPs in the GDF-9 gene and the – 482A G SNP in the AMHR2 gene were found to be unrelated. Similar content being viewed by others
