A woman born without a cervix or vagina successfully conceived and delivered a healthy son naturally, defying typical outcomes for patients who undergo reconstructive surgery. The case, documented in a recent report, highlights the unexpected potential for natural fertility even after extensive medical intervention.
The Initial Diagnosis and Condition
The patient, a 16-year-old girl in the United Kingdom, was referred to a gynecology clinic in 1999 due to amenorrhea – the absence of menstruation – despite experiencing cyclical pelvic pain. Diagnostic imaging (ultrasound and MRI) revealed a functional uterus but complete absence of both the cervix and vagina, a condition known as cervical agenesis. This rare condition affects an estimated 1 in 100,000 to 1 in 80,000 births. Vaginal agenesis often accompanies this, occurring in roughly 39% of affected individuals.
Surgical Intervention and Fertility-Sparing Approach
Rather than removing the uterus, the medical team opted for fertility-sparing surgery, performing a vaginoplasty to create a functional vagina with a surgically constructed cervical opening. The patient initially maintained continuous hormonal birth control to suppress bleeding, then transitioned to a cyclical regimen allowing for monthly menstruation.
Fertility Treatments and Unexpected Natural Conception
Years later, the patient and her partner attempted natural conception for a year without success. Subsequent fertility treatments, including intrauterine insemination (IUI) and three rounds of in vitro fertilization (IVF), also failed. The couple discontinued treatment due to financial constraints. Remarkably, in 2022 – eight years after the last IVF attempt – the patient conceived naturally and delivered a son via planned cesarean section on her 40th birthday.
Why This Matters
Natural conception after this type of reconstructive surgery is uncommon. A systematic review of 121 similar cases found only six resulting in natural pregnancies. This case is unique not just because of the natural conception but also because it occurred after failed assisted reproductive technologies. The patient herself expressed deep gratitude for her doctor’s unconventional approach, stating, “I am extremely grateful… for challenging the status quo… to help me have a normal sex life, menstrual cycle, become pregnant, and carry my own child.”
This case expands the understanding of reproductive possibilities for women with cervical and vaginal atresia. The long-term fertility potential remains unpredictable, but this example offers renewed hope for natural conception even after years of unsuccessful intervention.
