What is uterine fluid and why is it a problem for IVF?

Uterine fluid is an accumulation of liquid in the uterine cavity that can be seen on ultrasound. It's problematic for IVF because it can wash out the embryo, dilute important implantation factors, or create a hostile environment that prevents the embryo from attaching to the uterine wall, reducing success rates by up to 50%.

How is uterine fluid detected before embryo transfer?

Uterine fluid is typically detected during routine transvaginal ultrasound monitoring before embryo transfer. The fluid appears as a dark (echo-free) area within the uterine cavity. Even small amounts (>3mm) can be significant and warrant treatment before proceeding with transfer.

How is uterine fluid treated before IVF?

Treatment depends on the cause but may include aspirating the fluid with a thin catheter, treating hydrosalpinx surgically or with tube removal, antibiotics if infection is suspected, adjusting hormone medications, or performing hysteroscopy to address polyps or adhesions. The transfer may be postponed until the issue resolves.

Should embryo transfer be cancelled if fluid is found?

Not always. Small amounts of fluid may resolve spontaneously or be aspirated immediately before transfer. However, significant fluid or fluid from hydrosalpinx often requires cancelling the fresh transfer, freezing embryos, treating the underlying cause, and planning a frozen embryo transfer once resolved.

Can uterine fluid return after treatment?

Yes, fluid can recur, especially if the underlying cause isn't fully addressed. That's why identifying and treating the root cause (like hydrosalpinx) is important. Close monitoring with ultrasound before each transfer helps ensure the uterine cavity is optimal for implantation.

OPTIMIZING IVF SUCCESS

Managing Uterine Fluid for IVF Success

Creating the optimal environment for embryo implantation

For embryo transfer to be successful, the uterine lining must be stable and receptive. In some women, fluid buildup in the uterine cavity can interfere with implantation and significantly lower pregnancy chances. At Advanced Fertility Center of Texas (AFCT), we take a proactive approach: we identify and treat uterine fluid before transfer to give every embryo the best possible chance, avoiding the frustration of failed cycles due to preventable issues.

What Causes Uterine Fluid Buildup?

Uterine fluid buildup can impact fertility and implantation success. Understanding the underlying causes helps determine the most effective treatment approach for your specific situation.

Uterine fluid may develop due to:

Hormonal imbalances during IVF stimulation
Blocked or hydrosalpinx fallopian tubes leaking fluid into the uterus
Chronic endometritis or low-grade infection
Excess estrogen exposure or inflammatory conditions
Immune-related or autoimmune factors affecting the endometrium

IVF CONSIDERATIONS

Why Is Uterine Fluid a Problem?

Creates an unstable environment that prevents implantation
May signal infection or inflammation
Strongly linked to lower IVF success rates
If excess fluid is seen during your lining check or before transfer, proceeding without treatment can drastically reduce your chances of pregnancy

Early detection and proper treatment of uterine fluid can significantly improve your IVF success rates. Our team carefully monitors and addresses any fluid concerns before proceeding with embryo transfer.
