Prevalence and Causes of Recurrent Abortion among Women in Beni-Suef Governorate
Research Abstract
Abstract: Objective: The current study searched for prevalence, causes or risk factors and how to prevent recurrent
abortion among women in Beni-Suef Governorate. In women, progesterone is a hormone produced mainly in the
ovaries. After an egg is released by the ovaries (ovulation), progesterone helps make the uterus ready for
implantation of a fertilized egg. Peri-implantation pregnancy loss contributes to more than 20% of unexplained
infertility. Deficient hormone levels result in aberrant growth and support of the uterine lining making it un-ideal for
implantation. Polymorphisms within the progesterone receptor (PGR) gene, allele and genotype frequencies of
patients with repeated abortions were compared also to a control group. Design: Risk factors of abortion like age,
consanguinity, drug abuse, hormonal disturbances, and exposure to fever, X-rays or smoke during their pregnancies
in a group of 40 women with repeated abortions compared with controls matched in number and whom their
pregnancies were completely normal. Serum progesterone and the locus rs590688of their PGR were screened for
single nucleotide polymorphisms (SNP). Results: There was a significant difference between patients and control
groups in risk factors and in the serum progesterone levels (p<0.001). The SNP was detected (locus rs590688). The
more frequent wild type (*1) allele and the rarer (*2) allele were found in the control group and in the study group at
different frequencies (control group: *1/*1: 70%, *1/*2: 27.5%, *2/*2: 2.5%; patient group: *1/*1: 35%, *1/*2:
47.5%, *2/*2: 17.5%). The genotypes distributions differed significantly from each other (P<0.001). Conclusions:
The data suggest that the rarer PGR allele may be associated with an increased likelihood of repeated abortions to its
multi-factorial causes. Couples who experience recurrent pregnancy loss may benefit from a medical evaluation and
psychological support.
