ABSTRACT

INTRODUCTION: Mixed gonadal dysgenesis (MGD) is a rare disorder of sexual development. The management of MGD is challenging since the disease significantly impacts a patient’s growth, hormone balance, and gonadal development. This article used a large population and a long follow-up period for its analysis.

OBJECTIVES: This study aims to summarize the gender determination basis and analyze the long-term follow-up of mixed gonadal dysgenesis.

METHODS: A total of 45 patients’ clinical data were summarized and analyzed. Patients were divided by gender. Next, we followed up regarding the occurrence of complications after surgery, the patients’ satisfaction with external genitalia appearance, the growth of the patients, counting the surgical pattern the incidence of surgical complications and the development of the patients’ growth. All patients included in this study underwent chromosomal karyotype analysis, abdomen exploration, and pathological biopsy. After sex determination, 7 patients who were raised as female underwent clitoroplasty, and bilateral gonadectomy. 38 male patients underwent urethroplasty + one-sided gonadectomy.

RESULTS: Patient follow-up started in the third month after surgery. Female patients reported no surgery-related complications, while 14 male patients showed surgery-related complications. Additionally, 20 male patients (60.6 %) had a lower height compared to normal peers, 12 of which (36.4 %) were lower than the second standard deviation of the height of normal peers.

CONCLUSION: The clinical manifestations of mixed gonadal dysgenesis are variable, and the management is complicated. Children’s gonadal function, external genital conditions, psychological evaluation, and parents’ wishes should be considered before sex determination. In China, most patients are raised as males with a high incidence of postoperative complications. We found that short stature is a common feature in male patients, thus their height and growth should be carefully supervised. Patients should pay attention to their sexual function and sexual potential during adulthood.
