Instances of tumors arising in the gonads of individuals with 46,XX ovotesticular DSD are uncommon. We report a case of a 36-year-old phenotypical male with a chief complaint of an abdominal mass for 3 months. He reported normal erections and regular menses. Computerized tomography showed a large tumor measuring 15 × 10 cm in size, a uterus, and a cystic ovary. 46, XX ovotesticular DSD with seminoma. The patient was treated with neochemotherapy (etoposide and cisplatin), surgery, chemotherapy, and testosterone replacement. At the 13-month follow-up, the patient reported satisfactory erections, and no evidence of disease was found. Cases of 46,XX ovotesticular DSD with seminoma are uncommon. Our case reveals the importance of surgery combined with neochemotherapy, chemotherapy, and testosterone replacement in these patients to improve the prognosis.

The current study is a meta-analysis designed to assess the effect of adding magnesium to a combination of intrathecal bupivacaine and fentanyl. The protocol was registered in PROSPERO with the number CRD42020177618. PubMed, Cochrane library, Web of Science, and Google Scholar were searched for randomized controlled trials investigating the effect of adding magnesium to a combination of intrathecal bupivacaine and fentanyl. The continuous data were presented as Ratio of means (RoM). Risk ratio (RR) along with 95% confidence interval (CI) was utilized to assess the dichotomous data. Ten trials were involved in the present study with 720 adult patients. Compared with control, intrathe
