Ovotesticular disorder of sexual development manifested as hematospermia: a case report and literature review.

BACKGROUND

Ovotesticular disorder of sexual development (OT-DSD) is a rare sexual development disorder defined by the simultaneous existence of testicular and ovarian tissues (including follicular) in the same- or opposite-sex glands of an individual, with an incidence rate of about 1 in 100 000.

AIM

This report aims to supplement the clinical presentation, pathology, diagnosis, and treatment of OT-DSD and to improve the diagnostic ability of clinicians for modified disease.

METHODS

This article is a retrospective analysis of a case of OT-DSD at our institution. Additionally, a comprehensive search of the PubMed database with the keywords "ovotesticular disorder of sexual development" or "true hermaphroditism" was conducted between 1956 and 2024, resulting in approximately 250 cases, and the results of the search are summarized.

RESULTS

The patient, a 44-year-old male, sought treatment at our hospital on February 6, 2023, primarily due to "intermittent hematospermia for over a month." He stated that it was discovered during infancy that his right scrotum was empty and lacking a testicle. Due to the low local medical services and the low-income family's economic conditions, he did not seek further diagnosis and treatment. After admission, the patient underwent computed tomography and magnetic resonance imaging and decided to undergo robot-assisted pelvic mass resection, which was pathologically confirmed as OT-DSD.

OUTCOMES

The patient's definitive diagnosis was provided by postoperative pathology, and although the patient ultimately had a favorable outcome, diagnosis and treatment were delayed due to his atypical clinical presentation.

STRENGTHS AND LIMITATIONS

This is a single case report; however, uncommon clinical presentations of rare diseases were identified, and a literature review was conducted. Unfortunately, there are some important missing data in the patient's medical history, including hormone assessment (testosterone, luteinizing hormone, follicle-stimulating hormone), tumor marker examination, semen analysis, scrotal ultrasound, and chromosomal analysis.

CONCLUSION

Patients with OT-DSD have diverse types of gonads, chromosomal karyotypes, and phenotypes of external genitalia, and further exploration and research are needed for early diagnosis and treatment. In addition, cases of OT-DSD with fertility and no ambiguous genitalia are even rarer. This case guides us for adult patients with no ambiguous genitalia: if there is an inability to palpate 1 or both gonads and there is intermittent hematospermia, the possibility of OT-DSD should be suspected.
