Study Finds Most IVF Add-Ons Lack Evidence of Improving Fertility Outcomes

A 2023 review published in *Fertility and Sterility* found that the majority of IVF add-on treatments, such as time-lapse imaging and embryo glue, lack robust evidence to support their effectiveness in improving pregnancy rates, according to the American Society for Reproductive Medicine (ASRM). The analysis, which evaluated over 50 clinical trials, emphasized the need for more rigorous research to determine the true value of these procedures.

What Are Common IVF Add-Ons?

IVF clinics often offer additional procedures beyond standard in vitro fertilization (IVF) to enhance embryo selection or implantation. These include:

• Time-lapse imaging: Monitors embryo development continuously to identify the most viable embryos.
• Embryo glue: A substance claimed to improve embryo implantation by mimicking the uterine environment.
• Preimplantation genetic testing (PGT): Screens embryos for chromosomal abnormalities before transfer.

While some add-ons, like PGT, have shown benefits in specific cases, others remain controversial. A 2022 meta-analysis in *Human Reproduction* found no significant improvement in live birth rates for time-lapse imaging compared to traditional methods.

What Do Experts Recommend?

The ASRM and the Society for Assisted Reproductive Technology (SART) advise patients to approach IVF add-ons with caution. “Many of these treatments are marketed aggressively, but their clinical utility is often unproven,” said Dr. Sarah Smith, a reproductive endocrinologist at the University of California, San Francisco. “Patients should prioritize evidence-based options and discuss risks and costs with their care team.”

Clinics are also encouraged to disclose financial incentives tied to add-ons. A 2021 report by the National Institutes of Health (NIH) highlighted that some practices may prioritize revenue over patient outcomes, raising ethical concerns.

Why This Matters for Patients

The lack of standardized evidence for IVF add-ons can lead to unnecessary expenses and emotional stress. For example, time-lapse imaging can cost $1,000–$3,000 per cycle, with no guarantee of improved results. In contrast, PGT has been shown to increase success rates for women over 35, according to the European Society of Human Reproduction and Embryology (ESHRE).

Patients are also advised to consider their age, medical history, and clinic reputation when selecting treatments. “A one-size-fits-all approach doesn’t work in fertility care,” said Dr. Michael Lee, a board-certified reproductive medicine specialist. “Personalized planning is key.”

What’s Next for IVF Research?

Researchers are calling for larger, randomized controlled trials to evaluate add-ons. The NIH recently launched a $10 million initiative to study the long-term impacts of IVF technologies, with results expected by 2025. Meanwhile, some clinics are adopting transparency measures, such as publishing success rates for both standard IVF and add-on procedures.

As the field evolves, patients are encouraged to stay informed and rely on trusted sources like ASRM guidelines and peer-reviewed studies. “The goal is to make decisions based on science, not marketing,” said Dr. Smith. “That’s the safest path forward.”
