Uterine Prolapse and Infertility
Uterine prolapse is not a recognized cause of infertility in standard medical guidelines, though rare case reports suggest severe prolapse may occasionally contribute to difficulty conceiving in individual cases.
Evidence from Major Guidelines
The most comprehensive and recent guidelines on female infertility do not list uterine prolapse among the established causes of infertility:
The American College of Radiology's 2020 guidelines on female infertility identify the main causes as: ovulatory disorders (21%), tubal damage (14%), male factor (26%), endometriosis (affecting one-third of infertile women), and uterine cavity abnormalities that interfere with implantation 1, 2.
Uterine cavity abnormalities that cause infertility specifically refer to intrauterine synechiae, Müllerian anomalies, fibroids, and conditions affecting implantation—not prolapse 1, 3.
Structural uterine abnormalities identified in recurrent pregnancy loss (up to 38% of cases) relate to cavity shape and cervical incompetence for second-trimester losses, not prolapse 3.
Clinical Context and Mechanism
The absence of prolapse from infertility guidelines reflects important mechanistic considerations:
Prolapse affects pelvic floor support structures but does not inherently damage the endometrial cavity, fallopian tubes, or ovarian function—the anatomical components essential for conception 1.
Pelvic floor dysfunction guidelines focus on quality of life issues (urinary incontinence, defecatory dysfunction) rather than fertility impacts, as these conditions primarily cause morbidity without affecting reproductive capacity 1.
Severe prolapse could theoretically alter cervical position or coital mechanics, but this is not documented as a clinically significant cause of infertility in the medical literature 1.
Limited Case Report Evidence
There is minimal published evidence suggesting any fertility connection:
One 2010 case report described a woman with 11 years of primary infertility who conceived after conservative surgery for uterine prolapse, representing "apparently the first case of its kind" 4.
This single case does not establish causation and may represent coincidental timing rather than a causal relationship 4.
Fertility-sparing prolapse repairs (Manchester-Fothergill procedure, hysteropexy) are performed in young women, with subsequent pregnancy rates and prolapse recurrence (12% overall) documented, but these procedures address prolapse symptoms, not infertility 5, 6.
Pregnancy Outcomes with Prolapse
When prolapse and pregnancy do coexist, the concern is obstetrical complications rather than conception difficulty:
Gravid uterine prolapse (prolapse during pregnancy) occurs in approximately 1 in 4,209 deliveries and is associated with preterm labor, cervical insufficiency, postpartum hemorrhage, and uterine atony—but these are complications of existing pregnancy, not barriers to conception 7, 8.
Women with prolapse can and do conceive, as evidenced by documented pregnancies in primigravid women with prolapse 7.
Clinical Recommendation
For women of reproductive age presenting with infertility, standard evaluation should focus on the established causes: ovulatory function assessment (antral follicle count, ovarian volume via transvaginal ultrasound), tubal patency evaluation (hysterosalpingography), assessment for PCOS, endometriosis, and male factor evaluation 1, 2.
Uterine prolapse should not be considered a primary target in the infertility workup unless severe anatomical distortion is present that could mechanically interfere with intercourse or sperm transport—an exceptionally rare scenario not supported by guideline-level evidence 1, 2.
