The Future of Fertility Treatment: New Technologies Transforming IVF

In short: Fertility treatment is advancing quickly: ultra-rapid freezing of eggs (vitrification), better culture media for growing embryos to the blastocyst, artificial intelligence for choosing sperm and assessing embryos, and stem-cell research to support the ovary and renew the uterine lining. Future techniques such as producing eggs and sperm in the laboratory and artificial wombs raise legal and ethical questions and may not be accepted in every country.

Fertility care is going through one of the most exciting and transformative periods in its history. New technologies are helping make treatment more effective, more personalized, and often less invasive for patients hoping to build their families.

These advances are improving outcomes and allowing fertility specialists to tailor treatment to each patient’s unique needs.

Why do these new advances matter to patients?

• They can make treatment less invasive
• They can make treatment more accessible

This article explores some of the most significant developments shaping the present and future of fertility treatment — many of which are already changing how patients and doctors approach conception.

Some of the most promising advances being researched and developed today include:

• Retrieving eggs from a woman’s ovaries and freezing them for future use, giving women more flexibility in planning their families.
• Removing a small part of the ovary containing immature eggs and freezing it, so that when needed, the eggs can be matured later in the laboratory.

New freezing methods are also improving how well eggs survive after thawing, such as ultra-rapid vitrification and artificial intelligence-assisted freezing protocols.

These freezing techniques can be especially valuable for women whose fertility may be at risk due to radiotherapy or chemotherapy treatment.

• Improvements in the culture media used to grow embryos in the IVF laboratory up to the blastocyst stage (five days after fertilization), where the healthiest embryos can be identified. This allows doctors to transfer just one or two embryos, increasing the chances of pregnancy while lowering the risk of multiple pregnancy that comes with transferring several embryos.
• Advances in computer technology now allow sperm to be assessed for intracytoplasmic sperm injection (ICSI) with computer or AI assistance, which may reduce human error; these methods are still being evaluated and have not yet been proven to increase the chance of a live birth, so they may be considered in selected cases, such as repeated fertilization failure or poor embryo quality.
• The growing use of artificial intelligence in fertility treatment:
• Many AI models are being explored to support diagnosis and treatment planning.
• Some models aim to help predict which embryos may have the highest implantation potential.
• Other models are being studied to help predict the likelihood of live birth.
• Some AI tools are being used to help detect sperm DNA fragmentation.
• Time-lapse embryo monitoring (continuous imaging) combined with AI is being used to support embryo grading.
• The use of stem cells for ovarian support:

Researchers are studying how pluripotent stem cells might help support egg maturation outside the ovary, potentially allowing for much lower hormone doses and shorter stimulation periods in the future.

• Stem cells are also being studied for their potential to help rejuvenate ovaries in women with diminished ovarian function.
• Similarly, stem cells are being explored to help rejuvenate the endometrium for women with a thin uterine lining.

Stem cell research

This area of research is still confined to laboratories, but it holds great promise. For example, stem cells could potentially be collected from boys before puberty and frozen for future use — which may help boys who will undergo chemotherapy. This research may also one day help infertile men by encouraging stem cells to produce sperm.

• Uterine Receptivity Analysis (ERA): A test that aims to determine the best day for embryo transfer, when the endometrium is most receptive. Studies so far have not shown that it increases the chance of a baby for most women, so it is not recommended routinely, but it may be discussed with selected patients who have had repeated implantation failure.
• Microbiome-Based Treatments: Testing the vaginal and uterine microbiome to study whether the environment is well-suited for embryo implantation. This is still a research area, and international guidelines do not yet recommend routine testing or treatment outside clinical studies.
• In Vitro Gametogenesis (IVG): A research method using non-reproductive cells (such as skin cells) to potentially create eggs or sperm, which could one day help men and women facing severe infertility, such as premature ovarian failure or azoospermia.

10 - Using split cells instead of sperm

This method is still under research. Human cells normally contain 46 chromosomes, including two sex chromosomes — women have two X chromosomes, and men have one X and one Y chromosome. During natural fertilization, an egg containing 22 chromosomes plus one X chromosome fuses with a sperm containing 22 chromosomes plus either an X or Y chromosome. Researchers are exploring whether a cell from a man’s body, such as a blood cell, could be split in the laboratory so that each half — containing half the usual chromosome number — could be injected into an egg using the ICSI method. If successful, this research could one day offer new options for men who have no sperm in their semen or testicles.

11 - Techniques to correct genetic abnormalities (gene editing) in embryos before transfer into the uterus

12 - Artificial Wombs (Ectogenesis): Researchers are developing external environments that aim to mimic the womb, supporting embryo and fetal growth outside the mother’s body.

These would use specialized incubators designed to provide a suitable environment for fetal growth and development, supplying nourishment and oxygen until maturity. This research may one day help premature babies, or support women for whom pregnancy would be risky, women born without a uterus, or those with significant uterine abnormalities.

13 - Intrauterine culture of embryos

This method is still under research. It involves placing eggs and sperm inside a small container made of a dissolvable material, which is then placed inside the uterus. Over about a week, the material dissolves naturally, releasing the embryo inside the uterus at the time it would normally arrive there. A key challenge is finding a material that works well for this purpose without being rejected by the uterus.

14 - Robotic-assisted procedures: The use of robotic technology to help perform certain fertility-related procedures and, in some cases, surgeries.

Many of these technologies also involve legal and ethical considerations, which means some may not be available or approved in every country. That said, this does not diminish their potential value and usefulness in appropriate cases.
