Many fertility specialists recommend removing an endometrial polyp before embryo transfer. Hysteroscopic polypectomy is usually a short outpatient procedure, and a polyp could interfere with implantation. The research isn’t conclusive, especially for small polyps, so the decision depends on the polyp and your history. If you’re traveling to Colombia for IVF, the main planning question is when to remove it so your trip isn’t delayed.
- Polyps are usually found on ultrasound or saline sonogram, and confirmed and removed during hysteroscopy.
- High-quality trial evidence is limited. A Cochrane review found no good-quality data supporting routine polyp removal before IVF. Even so, many specialists remove polyps before transfer because the procedure is low risk.
- Polyps usually don’t affect egg retrieval. They mainly matter for transfer timing.
- A polyp found during stimulation often leads to a freeze-all cycle, with removal before a later frozen transfer.
What an endometrial polyp is
An endometrial polyp is an overgrowth of the uterine lining that projects into the cavity. Polyps are usually benign. They can be single or multiple and range from a few millimeters to several centimeters. Many cause no symptoms. Others cause bleeding between periods, heavy periods or spotting after sex. Polyps are often sensitive to estrogen, which is relevant during IVF because stimulation raises estrogen levels.
Polyps are a common finding in fertility workups. They’re also common in people who don’t have trouble conceiving, so finding one doesn’t necessarily mean it’s the cause of infertility.
How polyps are found
| Method | What it shows | Notes |
|---|---|---|
| Transvaginal ultrasound | A thickened or irregular area of the lining | Often best seen in the first half of the cycle, after the period ends, when the lining is thinner |
| Saline infusion sonogram | Fluid outlines the polyp within the cavity | Better than standard ultrasound at telling polyps from normal lining |
| 3D ultrasound | A detailed view of the cavity | Depends on the equipment and operator |
| Hysteroscopy | Direct view of the polyp | Confirms the diagnosis and allows removal in the same procedure |
An HSG may show a filling defect, but it can’t reliably distinguish a polyp from a fibroid or an air bubble. Our guide to hysteroscopy before IVF explains when clinics recommend direct evaluation of the cavity.
Remove first or proceed? What the evidence says
The honest answer is that the research is incomplete. A Cochrane review of hysteroscopic polyp removal before assisted reproduction found no good-quality randomized trial evidence supporting the routine removal of polyps before IVF. That doesn’t mean removal is useless. It means the question hasn’t been studied well enough to settle. Many of the studies that exist are observational or involve IUI rather than IVF.
In practice, many reproductive endocrinologists remove polyps before embryo transfer, for a few reasons:
- A polyp physically occupies space in the cavity where an embryo needs to implant.
- Polyps may affect the lining around them, not just the spot where they sit.
- Hysteroscopic polypectomy is generally low risk and quick to recover from.
- Removed tissue can be examined by a lab to confirm it’s benign.
Approaches to small polyps vary more. Some specialists will proceed with transfer if a polyp is very small and located away from the expected implantation area. Others remove every polyp they find. Factors your specialist may weigh include the size, number and location of the polyps, any symptoms, your history of failed transfers, and whether a hysteroscopy is already planned.
Note: This is a decision to make with a qualified reproductive endocrinologist who has seen your images. If two specialists give you different advice, ask each one to explain their reasoning. Both may be reasonable choices.
Hysteroscopic polypectomy: what to expect
Polypectomy is done through the cervix with a hysteroscope, so there are no incisions. Depending on the clinic and the size of the polyp, it may be done in an office setting with local anesthetic or in an operating room with sedation. Many people go home the same day and return to normal activities within a day or two. Your surgeon will give you specific instructions.
- Timing. Procedures are often scheduled in the first half of the cycle, after your period, when the lining is thinner and the view is clearer.
- The procedure. The surgeon removes the polyp with fine instruments or a resection device and checks the rest of the cavity.
- Pathology. Removed tissue is usually sent to a lab. Ask how you’ll receive the results if you’re abroad.
- Recovery. Mild cramping and light spotting for a few days is common. Follow your surgeon’s instructions about activity.
- Moving on to transfer. Your specialist will advise how long to wait. Many clinics move to stimulation or frozen transfer in a following cycle, but the timing varies.
Timing polypectomy around stimulation and transfer
Found before you start
If a polyp shows up in your pre-IVF workup at home, the simplest plan is often to have it removed at home before you travel. Then send the operative report, pathology and a follow-up image to the Colombian clinic. Your trip goes ahead with a clear cavity, and you avoid adding a procedure to your stay.
Found during stimulation
Sometimes a polyp appears or becomes visible during stimulation, as estrogen rises and the lining thickens. A common approach is a freeze-all cycle: continue stimulation and retrieval, freeze the embryos, remove the polyp, then transfer in a later frozen cycle. Our guide to frozen vs fresh embryo transfer explains why frozen transfers are often preferred in situations like this.
Found before a frozen transfer
If a polyp is found on a pre-transfer scan, the transfer is often postponed until it’s removed. Embryos remain safely frozen in the meantime.
What it means for your Colombia trip
| Scenario | Likely impact on travel |
|---|---|
| Removed at home before traveling | Usually no added time in Colombia |
| Removed in Colombia before stimulation | May add days to your stay, or shift your start to the following cycle |
| Found during stimulation (freeze-all) | Retrieval proceeds. Transfer happens on a later trip. |
| Found before a frozen transfer | Transfer may be postponed, which can mean rebooking travel |
Because of these possibilities, many patients with a known or suspected polyp plan for two trips: one for retrieval and one for transfer. See two-trip vs one-trip protocols. For pricing of IVF and add-on procedures, see the IVF cost in Colombia guide.
Tip: Send your ultrasound or saline sonogram images, not just the written report, to the Colombian clinic before your consultation. The specialist may be able to tell you in advance whether they’d remove the polyp, which helps you decide where to have it done.
Coordinating care at home and in Colombia
- Ask your home gynecologist or reproductive endocrinologist for a saline sonogram if a standard ultrasound was unclear.
- If polypectomy is recommended, ask whether it can be scheduled before your travel dates.
- Request the operative report, pathology report and photos.
- Send everything to the Colombian clinic and confirm they’re comfortable proceeding.
- Ask the clinic whether they want a follow-up scan before transfer.

Frequently asked questions
Do all endometrial polyps need to be removed before IVF?
Not necessarily. Many specialists remove them before transfer, but approaches to very small polyps vary, and high-quality trial evidence is limited. Your reproductive endocrinologist will weigh size, location and your history.
Can I do egg retrieval if I have a polyp?
Usually, yes. Polyps are in the uterus, and retrieval involves the ovaries. Many clinics proceed with retrieval, freeze the embryos and remove the polyp before a later transfer.
How long after polyp removal can I have an embryo transfer?
It varies by clinic and by the procedure. Many clinics plan transfer in a following cycle, but your specialist will set the timing based on how the cavity looks afterward.
Can polyps come back?
Yes, polyps can recur. If time passes between removal and transfer, your clinic may check the cavity again before transfer.
Is polypectomy painful?
Most people describe cramping during or after the procedure. Depending on the setting, it may be done with local anesthetic or sedation. Ask your surgeon what to expect for your procedure.
