Pericentric inversion of chromosome 1 and 9 in a case with
chromosomes 1 and 9 leading to recurrent miscarriage. Our study highlights the deleterious effect of pericentric inversion of chromosomes 1 and 9 on recurrent pregnancy loss. It also underlines the importance of performing cytogenetic studies for couples with such complaint. In such cases, a well informed genetic counseling should be
Cytogenetic Analysis of Couples with Recurrent Pregnancy Loss
Cytogenetic Analysis of Couples with Recurrent Pregnancy Loss Jisha P, Sanuj C Breezevilla and Dinesh Roy D. Abstract - The goal of this cytogenetic study was to evaluate the various risk factors and chromosome abnormalities in couples experiencing recurrent pregnancy loss (RPL). This study was conducted among couples with 50 RPL.

Proposed causes of recurrent pregnancy loss After having a first miscarriage, couples inevitably ask why this happened. The most frequent known cause of sporadic spontaneous abortion (SAB) is cytogenetic abnormalities of the conceptus. Half of preimplantation embryos examined and one-third of embryos that have

Current Update on Recurrent Pregnancy Loss
Recurrent pregnancy loss is an intense personal calamity to the couples and an arduous clinical challenge to the Obstetricians. When to evaluate and what constitutes a complete evaluation is still a state of flux.

If a diagnosis of luteal phase defect is sought in a woman with recurrent pregnancy loss, it should be confirmed by endometrial biopsy. Luteal phase support with progesterone is of unproven efficacy.

Genetic Considerations in Recurrent Pregnancy Loss
fetal aneuploidy occur at similar frequencies among women with sporadic and recurrent losses, some couples with recurrent pregnancy loss have additional associated genetic factors and some have nongenetic etiologies. Genetic testing of the products of conception from couples experiencing two or more losses may aid in deﬁning the underlying

Based on limited cytogenetic data, 36% 39% of miscarriages in couples with recurrent pregnancy loss associated with a structural genetic factor have an unbalanced structural rearrangement (18, 19). Treatment options should be based on whether repeated miscarriages
Recurrent Pregnancy Loss: Diagnosis and Treatment
Recurrent pregnancy loss, also referred to as recurrent spontaneous abortion (RSA) or recurrent miscarriage, is defined as two or more failed pregnancies (American Society for Reproductive Medicine ASRM, 2020) and may affect as many as 1 3% of childbearing women.

Sporadic pregnancy loss is nonconsecutive pregnancy loss that occurs randomly during a woman s reproductive years.

Background: Recurrent abortion is a difficult medical problem happening in about 1-2% of fertile women. Most spontaneous miscarriages which happen in the first and second trimesters are caused by chromosomal abnormalities. Objective: The present study tries to find the rate of chromosomal abnormalities in couples with recurrent pregnancy loss.
