Fallopian tube patency is crucial for natural pregnancy, and the modern HyFoSy method (hysterosalpingo-foam sonography) is now considered one of the safest and most accurate procedures for assessing tubal function. Although the focus is often placed on diagnosis (HyFoSy, HSG, laparoscopy), it is equally important to discuss prevention – how to keep the fallopian tubes healthy and functional.
What does fallopian tube patency mean?
The fallopian tubes are channels that connect the ovaries to the uterus. Fertilisation most commonly takes place inside them.
If the fallopian tubes are blocked or damaged, sperm cannot reach the egg, or the fertilised egg cannot reach the uterus.
Blocked fallopian tubes are the cause of infertility in 30–40% of women.
Preventive check-ups and tests
Gynaecological examinations – once a year
Infection swabs – whenever inflammation or discomfort is suspected
Ultrasound
HyFoSy – for couples who have been trying to conceive unsuccessfully for more than one year
A healthy lifestyle
Causes of blocked fallopian tubes
Infections (especially sexually transmitted infections, e.g. chlamydia and gonorrhoea)
Endometriosis and adhesions
Pelvic or abdominal surgery
Ectopic pregnancy (scarring of the fallopian tubes)
Congenital abnormalities of the uterus and fallopian tubes
The HyFoSy method – a modern approach
What is HyFoSy? It is an ultrasound method that uses a special contrast foam (ExEm gel) to show whether the fallopian tubes are patent.
Advantages over HSG (an X-ray examination):
No radiation
Less painful and uncomfortable
A quick procedure (15–30 minutes)
Visualises the uterus and endometrium at the same time
Specificity of approximately 95% (accurately identifies patent fallopian tubes)
Conclusion
Preventing blocked fallopian tubes comes down to preserving reproductive health through regular check-ups, protection against infections, and a healthy lifestyle.
HyFoSy is the latest and safest method for examining fallopian tube patency and is particularly suitable for women who have been trying unsuccessfully to conceive for more than one year. Compared with older methods, it provides an accurate diagnosis, minimal discomfort, and no radiation, making it the first choice in modern gynaecological practice.
