Evaluation of Steroid Receptors mRNA Fingerprints in Two Groups of Normozoospermic Patients: Men from Unexplained Infertility Couples vs. Men from Couples with Tubal Factor Infertility

چکیده
The study of sperm cellular components at molecular level is crucial for the diagnosis of male unexplained infertility. The aim of the study was to compare the molecular profile of steroid receptors and aromatase in spermatozoa obtained from two normozoospermic groups of patients issued from couples treated for infertility. We investigated 46 male patients from unexplained infertility couples and from men, 38 where female partners presented with tubal infertility. Sperm ERs (estrogen receptors: alpha and beta), GPER (G proteincoupled estrogen receptor), AR (androgen receptor) and aromatase mRNA expression levels by TaqMan qPCR were analyzed. AR transcript level was significantly lower in sperm of men from unexplained infertility couples vs. men from couples with tubal factor infertility (P = 0.04). Although the AR mRNA expression level did not had any effect on embryo development and its implantation, a significant correlation between AR mRNA levels and clinical pregnancy in unexplained infertility patients was observed. Taken together, AR transcript presence in ejaculated spermatozoa could be a potential marker for unexplained infertility.

Objective Approximately 15 percent of couples are infertile. The male factor is responsible for approximately 50% of the cases. One of the main genetic factors playing a role in male infertility is Y chromosomal microdeletion within the proximal long arm of the Y chromosome (Yq11), named azoospermia factor (AZF) region. Recent studies have also demonstrated that there is a potential connection ...
