IVF Add-Ons: Evidence Ratings for Every Treatment Clinics Sell You

PGT-A, endometrial scratch, embryo glue, time-lapse, assisted hatching — rated by evidence strength with Colombian pricing.

July 2026 · 10 min read

IVF clinics worldwide sell add-on treatments — optional extras that promise to improve your chances of success. Some are evidence-backed. Some are experimental. Some have been disproven. And all of them cost extra.

This guide rates the most commonly offered IVF add-ons using an evidence-based framework similar to the UK's HFEA traffic-light system, adapted for the Colombian clinic landscape. Our goal isn't to tell you what to do — it's to give you the information to have an informed conversation with your reproductive endocrinologist.

Evidence Rating System

Strong Evidence Multiple large RCTs showing consistent benefit for appropriate patient groups.
Moderate Evidence Some RCT evidence of benefit, but inconsistent or limited to specific subgroups.
Limited Evidence Observational data or small trials only; more research needed.
Insufficient / Disproven No credible evidence of benefit, or evidence of no benefit.

The Add-Ons Rated

Add-OnEvidenceTypical Extra Cost (Colombia)Verdict
PGT-A (preimplantation genetic testing for aneuploidy)Strong ✅$800–$2,000 per batchStandard of care for 36+; reduces miscarriage, improves per-transfer rates
ICSI (intracytoplasmic sperm injection)Strong ✅Often included in packageEssential for male factor; routine use debated for normal sperm
Embryo glue (hyaluronan-enriched transfer medium)Moderate 🟡$50–$150Small benefit suggested in some studies; low cost makes it reasonable
Time-lapse incubator monitoring (EmbryoScope)Moderate 🟡$200–$500Better embryo selection possible; stable culture environment is the real benefit
Endometrial scratchInsufficient ❌$100–$300Recent large RCTs show no benefit; falling out of favor globally
Assisted hatchingLimited 🟠$100–$300May help frozen embryo transfers and older patients; blanket use not supported
ERA (endometrial receptivity analysis)Limited 🟠$500–$1,000Personalized transfer timing; evidence of benefit in RIF patients is mixed
Growth hormone co-stimulationLimited 🟠$300–$800 per cycleSome evidence for poor responders; not universally beneficial
Intralipid infusionInsufficient ❌$100–$300Immunological theory not supported by robust evidence
PRP uterine infusionLimited 🟠$200–$500Experimental; thin-lining patients only; minimal safety concerns

The Three You Should Seriously Consider

PGT-A — For patients over 35, PGT-A testing of embryos before transfer is the single most impactful add-on. It doesn't create better embryos — it identifies which ones are chromosomally normal, preventing transfers that would result in miscarriage or failed implantation. The cost ($800–$2,000 for a batch of embryos) is substantial but often pays for itself by eliminating failed transfer cycles. Note: PGT-A in Colombia is scoped to chromosomal screening and genetic disease detection — never for family balancing or sex selection.

ICSI — If male factor infertility is involved (low count, motility, or morphology, or surgically retrieved sperm), ICSI is essential, not optional. Many Colombian clinics include ICSI in their base IVF package. If it's quoted separately, expect $400–$800.

Time-lapse monitoring — The EmbryoScope or equivalent time-lapse incubator allows continuous monitoring without removing embryos from optimal culture conditions. The embryo selection advantage is debated, but the culture-stability benefit is real. At $200–$500 in Colombia, it's a reasonable investment.

The Ones to Question

Endometrial scratch — Once widely promoted, recent large randomized controlled trials have failed to show benefit. If your Colombian clinic recommends it, ask what evidence they're relying on. It's not harmful, but it's uncomfortable and costs $100–$300 for a procedure that likely doesn't help.

Intralipid infusions — Based on the theory that some implantation failures are caused by immune system overreaction, intralipid infusions were briefly trendy. The immunological hypothesis hasn't held up in rigorous studies. If offered, ask for the specific evidence — don't accept "it can't hurt" as a rationale for spending money.

Key Takeaway
Not all IVF add-ons are created equal. PGT-A and ICSI (when indicated) have strong evidence of benefit. Time-lapse monitoring and embryo glue have moderate support at modest cost. Endometrial scratch and intralipids have weak or disproven evidence. Ask your clinic for the evidence behind every add-on they recommend — and make sure the cost is disclosed upfront.
