46 XY DISORDER

Abstract

Objectives: The Disorders of Sex Development are classified as 46, XY DSD,46, XX DSD and Chromosomal DSD according to the chromosomal constitution of the affectedpersons. 46, XY DSD is further classified into Androgen Synthetic Defect, Androgen InsensitivitySyndrome Gonadal Dysgenesis, 5-Alpha Reductase Deficiency, Persistent Mullerian DuctSyndrome and Isolated Hypospadias according to the pathophysiology of the disease. Theaim of present study was to classify 46, XY patients into their subclasses on the basis of theirhormonal profile and physical examination. Study Design: Observational descriptive study.Setting: Biochemistry Department University of Health Sciences for Karyotyping and Geneticassessment, and its allied institution Biochemistry Department Quaid-e-Azam Medical CollegeBahawalpur for hormonal analysis, along with Pediatric Medicine Departments of Quaid-e-AzamMedical College / Bahawal Victoria Hospital Bahawalpur for collection of Sample and clinicalassessments. Period: June 2015 to December 2015. Study Design: Observational descriptivestudy. Material and Methods: 53 patients with 46, XY DSD were recruited. Complete clinicalhistory and data of each patient was recorded in the research proforma. Genitals examinedfor the phallus length and size, position of urinary meatus, palpation of gonads and shape ofthe labioscrotal folds. Ultrasonography examination of each patient was performed to look forundescended testes and for the presence of either male or female internal reproductive organs.Results: Base line levels of serum Testosterone Dihydrotestosterone Luteinizing hormone,Follicle stimulating hormone, 17-OH-Progesteron and Anti-mullerian hormones were measuredby ELISA technique. Testosterone and DHT were measured again after hCG stimulation. Onthe basis of physical examination, ultrasonographic findings and hormonal profile diagnosisof the types of 46, XY DSD was possible in 27 (51%) of patients. Androgen synthesis defect asa cause of 46, XY DSD was diagnosed in 7(13%) patients, Androgen insensitivity syndrome in6(11%) patients, 5-Alpha reductase deficiency in 3(6%) patients, Gonadal Dysgenesis in 3 (6%),Persistent Mullerian Duct Syndrome in 3(6%) and Isolated Hypospadias in 2 (4%) patients.There were 26 (49%) patients which remain undiagnosed with the algorithm of diagnosis usedin the present study.
