Tubal and Uterine Infertility
Tubal and uterine infertility groups the anatomic causes of female infertility — disorders of the fallopian tubes and of the uterus that impair gamete transport, fertilisation, embryo implantation, or the maintenance of pregnancy. It sits within reproductive medicine alongside ovulatory and unexplained causes, and it organises clinical entities such as tubal obstruction, endometriosis, congenital uterine malformations, intrauterine adhesions, fibroids, and adenomyosis.
Definition
Tubal and uterine infertility refers to female subfertility attributable to anatomic or structural disease of the fallopian tubes or the uterus, as distinguished from ovulatory, cervical, peritoneal-endocrine, or unexplained causes.
Scope
This area is an orienting overview of the structural (anatomic) factors in female infertility. It frames how diseases of the tubes and uterus interfere with conception and implantation, and points to the detailed topic entries beneath it. It describes mechanisms and the evidence base; it is reference-educational and does not provide individualised diagnostic or treatment recommendations.
Sub-topics
Core questions
- Which structural disorders of the tube and uterus impair fertility, and by what mechanisms?
- How is each anatomic cause distinguished diagnostically (for example tubal patency versus uterine cavity assessment)?
- How strong is the causal link between a given lesion and reduced fecundity or implantation failure?
Key concepts
- Tubal factor infertility
- Uterine (cavity) factor infertility
- Gamete and embryo transport
- Implantation and endometrial receptivity
- Congenital versus acquired anatomic disease
- Hydrosalpinx
- Anatomic versus ovulatory causes
Mechanisms
Anatomic infertility arises when disease disrupts one of the mechanical or microenvironmental steps of conception. Tubal disease (obstruction, adhesions, hydrosalpinx) blocks oocyte pick-up, sperm transport, fertilisation, or embryo passage to the uterus, and a hydrosalpinx can additionally impair implantation by reflux of fluid into the cavity. Uterine disease impairs implantation and pregnancy maintenance: congenital malformations distort the cavity, intrauterine adhesions obliterate functional endometrium, and submucosal fibroids or adenomyosis alter the cavity and endometrial receptivity. Endometriosis contributes through pelvic adhesions, distorted anatomy, and inflammatory effects on gametes and implantation. The textbook framework of Speroff and the JAMA review by Carson and Kallen describe these anatomic factors as a distinct category within the infertility workup.
Clinical relevance
Anatomic causes account for a substantial share of female infertility and are central to the diagnostic evaluation of subfertile couples, including assessment of tubal patency and of the uterine cavity. This area explains how such lesions relate to reduced fertility for educational orientation; specific management decisions belong to clinicians and the cited guidelines, not to this reference entry.
Epidemiology
Tubal disease and uterine factors together represent a major fraction of identifiable female infertility, with the relative contribution varying by population and by the burden of pelvic infection. Congenital uterine anomalies are present in roughly 5-7% of unselected women in systematic-review estimates, with higher prevalence among women with infertility or recurrent loss (Chan et al., 2011). The randomized evidence that salpingectomy before IVF improves outcomes in women with hydrosalpinx (Strandell et al., 1999) illustrates how tubal pathology directly affects reproductive success.
History
Recognition of anatomic infertility advanced with hysterosalpingography in the early twentieth century, which made tubal patency and uterine cavity contour visible, and accelerated with laparoscopy and high-resolution ultrasound. Consensus classifications of uterine malformations and randomized trials on hydrosalpinx in the in-vitro fertilisation era refined how these structural causes are categorised and weighed.

Frequently asked questions
- What distinguishes tubal and uterine infertility from other causes?
- It refers to subfertility caused by anatomic or structural disease of the fallopian tubes or uterus, as opposed to problems of ovulation, the cervix, or causes that remain unexplained after evaluation.
- Why are the tubes and uterus grouped together here?
- Both are anatomic sites whose structural disease interferes mechanically or microenvironmentally with gamete transport, fertilisation, or implantation, so they form a coherent category of structural female infertility.
