Resource Guide: 46,XX Ovotesticular Difference of Sex Development

At a Glance

46,XX ovotesticular difference of sex development (DSD) is a rare, natural variation, not a medical emergency. Modern care emphasizes a multidisciplinary team approach, protecting bodily autonomy, and delaying irreversible genital surgeries until the patient can participate in decisions.

Welcome to the resource guide for 46,XX Ovotesticular Difference of Sex Development (DSD).

Whether you are a parent who just received this diagnosis for your newborn, or an adolescent or adult navigating a new diagnosis yourself, stepping into the world of DSDs can feel overwhelming. You will likely encounter unfamiliar medical terms, complex genetics, and big decisions.

The most important thing to know right now is that you are not alone, and this condition is a natural, albeit rare, variation of human development. A diagnosis of 46,XX ovotesticular DSD is not a sickness that requires a “cure,” nor is it typically a medical emergency.

Modern medicine has shifted significantly in how it approaches DSDs. Today, care focuses on protecting the patient’s bodily autonomy, delaying irreversible surgeries whenever possible, and utilizing a multidisciplinary team of specialists to support long-term physical and emotional health.

This guide is designed to empower you with evidence-based information so you can partner effectively with your medical team. It is broken down into five core sections:

01

Understanding 46,XX Ovotesticular DSD

Start here for a clear explanation of what the condition is, why the medical terminology has changed, and the most important stabilizing facts you need to know immediately.

02

The Biology and Diagnosis of 46,XX Ovotesticular DSD

Dive into the genetic “switches” (like SRY and SOX9) that cause 46,XX chromosomes to develop testicular tissue. This section also breaks down the diagnostic tools, from microarrays to pathology reports.

03

Medical Management and Surgical Decisions

Learn about the modern standard of care, the critical role of the Multidisciplinary Team (MDT), and why international guidelines now recommend delaying non-essential genital surgery.

04

Fertility, Puberty, and Long-Term Health

Explore the long-term outlook, including how puberty is monitored, why female fertility is often possible, the biological reasons behind male infertility in this condition, and how cancer risks are managed.

05

Navigating Gender Assignment and Psychological Support

For parents of infants, this section explains how a “sex of rearing” is recommended. For all patients and families, it covers the vital role of psychological support and how to talk about the diagnosis openly and honestly.

Take your time reading through these pages. Write down questions for your doctor, lean on your support systems, and remember that you have time to make informed, careful decisions.

Common questions in this guide

What is 46,XX ovotesticular DSD?
It is a rare, natural variation of human development where an individual has 46,XX chromosomes but develops both ovarian and testicular tissue. It is not a sickness or a medical emergency that requires a cure.
Does my child need immediate surgery for a DSD?
Generally, no. Modern medical guidelines recommend delaying non-essential and irreversible genital surgeries to protect the patient's future bodily autonomy. Surgery may only be needed early on if there is an immediate functional concern, such as a urinary issue.
Who should be involved in treating 46,XX ovotesticular DSD?
Care should be managed by a Multidisciplinary Team (MDT) rather than a single doctor. This team typically includes specialists in genetics, endocrinology, urology, gynecology, and psychology to support long-term physical and emotional health.
Can someone with 46,XX ovotesticular DSD have children?
Female fertility is often possible in individuals with 46,XX ovotesticular DSD because functional ovarian tissue may be present. However, biological factors related to the 46,XX chromosomes typically result in male infertility.
How is a sex of rearing chosen for an infant with a DSD?
Your multidisciplinary medical team will help recommend a sex of rearing based on comprehensive genetic testing, internal anatomy, and hormonal function. Ongoing psychological support is vital for parents during this process and for the child as they grow.

Questions to Ask Your Doctor

Curated prompts to bring to your next appointment.

  1. 1.Who will be my primary point of contact on the Multidisciplinary Team (MDT)?
  2. 2.What is the recommended timeline for our initial assessments and follow-up visits?
  3. 3.Are there any immediate functional concerns (like urinary issues) we need to address right now?
  4. 4.Can you explain the specific genetic results and how they apply to my/our case?
