Woman Conceives Naturally After Surgery for Rare Cervix & Vagina Absence

The story of a woman in the United Kingdom who conceived and carried a son to term despite being born without a vagina or cervix is a remarkable testament to medical ingenuity and the resilience of the human body. The case, detailed in a recent case report, highlights the complexities of congenital reproductive anomalies and the evolving possibilities for women facing such challenges.

Understanding Cervical and Vaginal Agenesis

The patient first presented at a pediatric-adolescent gynecology clinic at age 16, experiencing pelvic pain that mirrored a menstrual cycle, despite never having had a period. This absence of menstruation, known as amenorrhea, prompted further investigation. Diagnostic imaging – including pelvic ultrasound and MRI – revealed a uterus but crucially, no cervix or vagina. These findings were confirmed through a minimally invasive surgical procedure called laparoscopy. The condition, cervical agenesis (the complete absence of a cervix), is rare, affecting an estimated 1 in 100,000 to 1 in 80,000 births. It often occurs alongside vaginal agenesis, where the vagina is also absent or underdeveloped. One study found vaginal agenesis in approximately 39% of women with a missing or malformed cervix, though the rate may be higher in cases of complete cervical agenesis.

A Path to Fertility Preservation

Traditionally, cases of complete cervical and vaginal agenesis have been managed with hysterectomy – the surgical removal of the uterus. However, in this instance, the medical team prioritized fertility preservation. After careful consideration and discussion with the patient and her family, they opted for a reconstructive surgical approach. This involved a vaginoplasty, a procedure to create a functional vagina with a cervical opening connected to the uterus.

Following the surgery, the patient managed her menstrual cycle with oral contraceptives, initially taking them continuously to prevent bleeding, then transitioning to a cyclical regimen to allow for monthly periods. Years later, at age 28, she discontinued birth control with the intention of starting a family. After a year of attempting to conceive naturally, the couple sought assistance from fertility specialists. Initial hormone testing revealed a slightly lower-than-average egg count for her age and a pelvic MRI showed some accumulated menstrual blood within the uterus, potentially indicating scar tissue.

Navigating Fertility Treatments and Unexpected Pregnancy

The couple underwent three rounds of intrauterine insemination (IUI), a process where sperm is directly placed into the uterus, but these attempts were unsuccessful. They then pursued in vitro fertilization (IVF), where eggs are retrieved, fertilized with sperm in a laboratory, and then transferred to the uterus. Despite three rounds of IVF also failing, the patient remarkably conceived naturally eight years after her last IVF cycle. She delivered a healthy son via elective cesarean section on her 40th birthday.

The Significance of This Case

What sets this case apart is the successful natural conception after reconstructive surgery for cervical and vaginal atresia. Natural pregnancy following such surgery is uncommon; a systematic review of 121 patients who underwent similar reconstructive procedures found that only six subsequently conceived naturally. The timing of the pregnancy, nearly a decade after unsuccessful fertility treatments, further underscores the unusual nature of this outcome.

Pelvic Health and the Importance of Seeking Support

This case also highlights the broader context of women’s pelvic health. Recognizing potential issues early is crucial. According to the Benenden Hospital, persistent pelvic pain and menstrual changes are key indicators that warrant medical attention. A 2023 survey by The Royal College of Obstetricians and Gynaecologists (RCOG) revealed that 60% of UK women experience symptoms of poor pelvic floor health, yet over half do not seek assist, often due to embarrassment or a belief that symptoms are normal.

As the patient herself expressed in a perspective included in the case report, she is “extremely grateful” to her doctor for challenging conventional approaches and pursuing innovative solutions to help her achieve her dream of motherhood. This case serves as a powerful reminder of the potential for medical advancements to expand reproductive options for women facing complex congenital conditions.

Looking Ahead: Continued research into congenital reproductive anomalies and advancements in reconstructive surgical techniques are essential. Further studies are needed to better understand the long-term outcomes for women who undergo these procedures and to optimize fertility preservation strategies. Increased awareness and open communication about pelvic health issues are also vital to ensure that women receive timely and appropriate care.
