A 26-year-old married man in Delhi has been diagnosed with a rare congenital condition after doctors investigating infertility discovered reproductive structures inside his abdomen that are typically associated with female development.
Doctors at RG Hospital in Rajouri Garden found a developed uterus, fallopian tube-like structures and abnormally positioned testicular tissue during the evaluation.

The patient was subsequently diagnosed with Persistent Mullerian Duct Syndrome (PMDS), a rare condition in which Mullerian structures remain in a person with a male chromosomal pattern.
Infertility Investigation Led to the Discovery
The man had been married for nearly two years and had been trying to start a family with his wife.
After medical evaluation found no apparent issue in his wife, doctors began investigating the husband’s fertility.
Although he had normal male secondary sexual characteristics, doctors found that both testes were absent from their normal position.
A semen analysis showed azoospermia, meaning no sperm were detected in the semen.
His testosterone level was reported to be within the normal range, while his FSH and LH levels were elevated.
Ultrasound and MRI Revealed Unexpected Structures
An abdominal ultrasound detected an unusual structure in the lower abdomen.
Doctors then conducted an MRI scan to investigate the finding in greater detail.
The imaging revealed a developed uterus and structures resembling fallopian tubes within the man’s abdomen.
Further testing showed that he had a 46,XY chromosomal pattern, which is typically associated with male biological development.
The combination of the imaging findings, reproductive anatomy and test results led doctors to diagnose PMDS.
What Is Persistent Mullerian Duct Syndrome?
Persistent Mullerian Duct Syndrome is a rare congenital condition that develops during fetal development.
During typical male fetal development, Anti-Mullerian Hormone (AMH) helps prevent the development of Mullerian structures. These structures would otherwise develop into organs such as the uterus and fallopian tubes.
According to the doctors involved in the case, PMDS can occur when AMH is absent or when its receptors do not function properly.
As a result, Mullerian structures may remain despite the individual having a 46,XY chromosomal pattern.
Why Were Doctors Concerned About the Testes?
The presence of undescended testes and other reproductive structures raised another concern for doctors: the potential risk of tumours and cancer.
The patient was therefore advised to undergo surgery.
A complex procedure was carried out to remove the affected structures.
Doctors subsequently examined the tissue that had been removed. According to the case details, pre-cancerous changes were detected in one of the testes.
The finding made the surgical intervention particularly significant because of the potential health risks associated with the abnormal testicular position and tissue changes.

Doctor Highlights Importance of Checking Undescended Testes
Dr Sushil Kharbanda, the urologist and infertility specialist who supervised the case, stressed the importance of identifying undescended testes at an early age.
He said parents should seek medical evaluation if a child’s testes have not descended into their normal position.
Early assessment can allow doctors to determine the cause and decide on appropriate treatment before complications develop.
Male Factors Should Not Be Overlooked in Infertility
The case also highlights the importance of evaluating both partners when a couple experiences difficulty conceiving.
Doctors noted that infertility can involve male as well as female factors.
A complete fertility assessment can help identify conditions that may otherwise remain undetected, particularly when there are no obvious external symptoms.
In this case, the patient’s physical appearance and normal secondary male characteristics did not reveal the unusual internal anatomy. The condition came to light only after doctors investigated the couple’s infertility.
A Rare Condition That Can Remain Undetected
PMDS is uncommon and can sometimes remain undiagnosed until adulthood.
The Delhi case demonstrates how an investigation for infertility can uncover congenital reproductive abnormalities that may not have been apparent earlier.
The discovery of pre-cancerous changes in the testicular tissue also underlines why undescended testes require appropriate medical evaluation and follow-up.
Frequently Asked Questions
What is Persistent Mullerian Duct Syndrome?
Persistent Mullerian Duct Syndrome, or PMDS, is a rare congenital condition in which Mullerian structures such as the uterus and fallopian tubes remain present in a person with a male chromosomal pattern.
What did doctors find in the 26-year-old Delhi man?
Doctors found a developed uterus, fallopian tube-like structures and abnormally positioned testes inside his abdomen during an infertility evaluation.
Why was the man undergoing medical tests?
He and his wife had been trying to conceive for nearly two years. After his wife’s evaluation was reported as normal, doctors investigated the man’s fertility.
What is azoospermia?
Azoospermia is a condition in which no sperm are detected in semen. It can have several possible causes and requires medical evaluation.
Why are undescended testes a concern?
Undescended testes can be associated with fertility problems and an increased risk of certain complications, including testicular cancer. Medical assessment is important.
Can PMDS be detected in childhood?
The condition may be identified during childhood, particularly when undescended testes are noticed. However, some cases can remain undiagnosed until adulthood.
