## TL;DR

This case report details the first successful in vitro fertilization and live birth in a woman with Alström syndrome, a rare genetic disorder.

## Contribution

The first documented live birth after IVF in a woman with Alström syndrome is reported.

## Key findings

- A euploid blastocyst transfer after ICSI and PGT-A resulted in a clinical pregnancy.
- The pregnancy was complicated by gestational diabetes and chronic hypertension, but was successfully managed.
- A healthy child was born at 38 weeks, weighing 3,110 grams.

## Abstract

Alström syndrome (AS) is an extremely rare, autosomal recessive genetic disorder. Fertility implications are particularly relevant for women affected by AS, and no cases of patients achieving pregnancy and live birth with in vitro fertilization (IVF) have been previously described. This case report describes the first worldwide live birth after IVF in a woman affected by AS.

This case report describes the IVF procedure and pregnancy management of an infertile woman suffering from AS.

After two intracytoplasmic sperm injections (ICSI), combined with preimplantation genetic testing for aneuploidies (PGT-A), a euploid blastocyst was transferred, resulting in a clinical pregnancy. Gestation was complicated by gestational diabetes mellitus and chronic hypertension, which were well controlled by specific treatments. At 38 weeks of gestation, a healthy child of 3,110 g was born.

The successful outcome of this rare case suggests that IVF is feasible in the case of women with AS, but a multidisciplinary, continuous follow-up aimed at controlling comorbidity-linked complications is needed.
