| Abstract | Background: Steroidogenic Factor 1 (SF-1), encoded by the Nuclear receptor subfamily 5 group A member 1 (NR5A1) gene, is a transcriptional factor crucial for adrenal and gonadal organogenesis. Pathogenic variants of NR5A1 are responsible for a wide spectrum of phenotypes with autosomal dominant inheritance including disorders of sex development, and oligospermia-azoospermia in 46,XY adults. Preservation of fertility remains challenging in these patients. Objective: The aim was to offer fertility preservation at the end of puberty in a NR5A1 mutated patient. Case report: The patient was born of non-consanguineous parents, with a disorder of sex development, a small genital bud, a perineal hypospadias, gonads in the left labioscrotal fold and the right inguinal region. Neither uterus nor vagina were detected. The karyotype was 46,XY. AMH and testosterone levels were low indicating testis dysgenesis. The child was raised as a boy. At 9 years old (y-o), he presented with a precocious puberty treated by triptorelin. At puberty, FSH, LH, and testosterone levels increased whereas AMH, inhibin B, and testicular volume were low suggesting an impaired Sertoli cell function and a partially preserved Leydig cell function. Genetic study, performed at almost 15 y-o, identified the new frameshift variant NM_004959.5: c.207del p.(Phe70Serfs*5) at a heterozygous state. He was thus addressed for fertility preservation. No sperm cells could be retrieved from three semen collections between 16 years and 4 months old to 16 years and 10 months old. A conventional bilateral testicular biopsy and testicular sperm extraction was performed at 17 years and 10 months but no sperm cells were found. Histological analysis revealed an aspect of mosaicism with seminiferous tubules that were either atrophic, with Sertoli cells only, or presenting an arrest of spermatogenesis at the spermatocyte stage. Conclusion: We report a case with a new NR5A1 variant. The fertility preservation protocol proposed at the end of puberty did not allow any sperm retrieval for a future parenthood. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
