New Delhi: In a bizarre incident, doctors in Kolkata discovered that the 30-year-old woman they were treating was born genetically male and suffering from testicular cancer. Her 28-year-old sister also then underwent necessay tests only to find out that she also had the same condition, known as ‘Androgen Insensitivity Syndrome’ — a condition in which a person is born genetically male, but has all physical traits of a woman.

The 30-year-old Birbhum resident, married for the last nine years, had visited city-based Netaji Subhas Chandra Bose Cancer Hospital with severe pain in lower abdomen a couple of months ago, following which clinical oncologist Dr Anupam Dutta and surgical oncologist Dr Soumen Das conducted her medical tests, and found out about her condition.

“From her appearance, she is a woman. Starting from her voice, developed breasts, normal external genitalia, everything is that of a woman. However, uterus and ovaries have been absent since birth. She has also never experienced menstruation,” Dr Dutta told PTI. Also Read - Kolkata Containment Zones: 18 Areas Contained in City Over Last 3 Days | Check List Here

It’s a very rare condition, and can be found one in every 22,000 people, he said.

After test reports suggested that the person has a “blind vagina”, doctors decided to conduct Karyotyping test, which revealed that her chromosome complement was ‘XY’ and not ‘XX’, as found in a woman.

“We conducted clinical examinations, after she complained of abdominal pain, and found out she has testicles inside her body. A biopsy was conducted, following which she was diagnosed with testicular cancer, also called seminoma, Dr Dutta explained.

Currently, she is undergoing chemotheraphy and her health condition is stable.

“As her testicles remained undeveloped inside the body, there was no secretion of testosterone. Her female hormones, on the other hand, gave her the appearance of a woman,” Dr Dutta stated.

“The person has grown up to be a woman. She is married to man for almost a decade. Currently, we are counselling the patient and her husband, advising them to continue living life as they have been,” Dr Dutta added.

The patient’s two maternal aunts were also diagnosed with Androgen Insensitivity Syndrome in the past, the oncologist said.

“It’s probably in the genes. We have come to know that two of her aunts from the maternal side were also suffering from similar condition,” he added.
