The emotional and physical experiences that accompany family building may be overwhelming, particularly when infertility issues arise or conception is not natural. For millions of people around the world, assisted reproductive technology has turned the rules upside down. In early 2026, the American Society for Reproductive Medicine reported a groundbreaking report stating that in any given year in America, over 100,000 babies are born through In Vitro Fertilization (IVF).

With this historic achievement, IVF is responsible for nearly 3% of all births in the United States, or approximately 1 in 36 babies. In fact, worldwide, it is estimated that over 10 million people have been conceived by assisted reproductive techniques. Nevertheless, the number of clinical steps, success rate and medical limitations can seem overwhelming. Here’s what beginners should know to ease their minds.

What the science says

In Vitro Fertilization is a complex, step-by-step medical process that involves collecting a woman’s eggs, manually combining them with sperm in a laboratory dish and implanting the resulting embryos into her uterus. After fertilization, the embryos are nurtured in a controlled environment and then placed back in the uterus.

According to the Mayo Clinic, an IVF cycle is a meticulous biological process that unfolds across several distinct clinical phases:

  • Ovarian stimulation: A patient receives daily hormone injections for eight to 14 days to stimulate her ovaries to grow multiple fluid-filled sacs, called follicles, which contain the eggs.
  • Egg retrieval: Once the follicles reach maturity, a reproductive endocrinologist utilizes a fine ultrasound-guided needle to safely retrieve the eggs from the ovaries while the patient is under light sedation.
  • Laboratory fertilization: The retrieved eggs are immediately combined with sperm in the lab, or directly injected with a single healthy sperm cell via Intracytoplasmic Sperm Injection (ICSI).
  • Embryo culture and screening: The fertilized eggs grow for three to five days into blastocysts. Clinicians frequently use non-invasive preimplantation genetic testing (niPGT-A) to assess chromosome numbers and prioritize only viable, healthy embryos for transfer.
  • Embryo transfer: A single healthy embryo is gently guided through a thin catheter directly into the uterine cavity, where it will hopefully implant and grow into a healthy pregnancy.

Many people seek to incorporate alternative therapies or lifestyle changes along with their clinical fertility treatments to ensure that they are as healthy as possible and that their stress levels are low.

Although some structural problems, such as completely blocked fallopian tubes, cannot be resolved with natural remedies. There are evidence-based, holistic methods that can help maintain metabolic balance, reduce inflammation throughout the body and improve blood flow to the reproductive organs during an active cycle.

Coenzyme Q10 (CoQ10) supplementation

Daily supplementation with Coenzyme Q10 is one of the most scientifically researched natural remedies used by fertility clinics. CoQ10 is an incredibly effective, natural antioxidant involved in cellular energy production, Healthline notes.

Peer-reviewed research shows that human eggs expend a tremendous amount of cellular energy during chromosomal division to accomplish this task accurately. As a woman gets older, her natural mitochondrial energy production decreases significantly, which is likely to increase the incidence of chromosomal abnormalities in her embryos.

Clinical data demonstrate that high-quality CoQ10 supports mitochondrial health and can be seen to enhance overall egg quality and embryo development in patients undergoing autologous retrieval.

Risks and safety considerations

Although modern laboratory technologies have reduced any risks and side effects associated with IVF to a minimum, it is still a complex medical procedure and intervention.

The most common physical risk of ovarian stimulation is called Ovarian Hyperstimulation Syndrome (OHSS), according to the Mayo Clinic. OHSS is a condition that can happen when the ovaries react to the hormones being injected in a way that causes fluid from the ovary to seep into the abdomen and the ovary to become painful and enlarged.

Symptoms may include nausea, bloating, severe stomach pain and rapid weight gain. In many modern 2026 protocols, this risk is eliminated by the “freeze-all” approach, in which all viable embryos are frozen, and the woman’s hormone levels and uterine lining regenerate before a frozen embryo transfer is performed.

“More than 100,000 babies born through IVF in a single year is a powerful reminder of how many families rely on reproductive medicine to build their families,” said SART President Dr. Jennifer Eaton, M.D., M.S.C.I. “These data also reflect the progress the field has made in improving accessibility, effectiveness and safety.”

Alternatives to In Vitro Fertilization

There are also highly effective alternatives to a full IVF cycle, available with modern reproductive medicine, if a couple prefers to try some less invasive options before going the full way.

Which alternative pathway is chosen depends on the couple’s specific fertility diagnosis, baseline age and underlying tubal health.

Intrauterine insemination (IUI)

For those couples who suffer from unexplained or mild male factor infertility and cervical mucus problems, a common first line of treatment is intrauterine insemination (also referred to as artificial insemination).

The Mayo Clinic says that an IUI cycle entails washing and concentrating the partner’s sperm sample to determine the healthiest, most motile cells. Then a specialist injects the concentrated sperm into the woman’s uterus through a thin tube (catheter) at the time of her natural ovulation.

This minor procedure completely bypasses the cervix and deposits a greater number of sperm closer to the fallopian tubes to encourage natural fertilization within the body and at a much lower cost than undergoing the entire IVF procedure.

What would disqualify you from IVF?

Although IVF is a very versatile treatment, in some cases, a person may be ruled out due to a serious medical condition or biological factors.

The absolute disqualifiers for an autologous cycle are if a woman has no uterus or no viable eggs at all, such as from early menopause or gonadotoxic chemotherapy, according to Cancer Research UK.

Also, a patient with severe unmanaged medical conditions may be disqualified. For example, a patient with advanced heart failure, malignancies or severe unmanaged hypertension will be disqualified, as the massive surge in hormones that occurs with ovarian stimulation and the physical stress of pregnancy will immediately pose a life-threatening risk to the mother. In such complicated circumstances, clinics endeavor to redirect families toward utilizing donor eggs, donor sperm or gestational surrogacy to reach their parenthood goals safely.

Do IVF babies have problems later in life?

According to Healthline, the majority of IVF-conceived children are completely healthy and normal, and do not differ in cognitive development, behavior or overall academic performance.

Although prior data showed a small statistical rise in low birth weight or premature delivery, more recent tracking suggests that these risks were influenced more by the large number of twins and triplets in the 1990s than by the laboratory procedure itself.

Dr. Justus Rabach, MD, tells Blavity Health, “Key insights from the latest fertility data show that the vast majority of IVF births in recent years have been singletons. The widespread switch away from multi-embryo transfer (MET) has successfully driven twin pregnancy rates down to a new low. To completely avoid the serious risks associated with multiple pregnancies, choosing elective single embryo transfer (eSET) remains the safest approach.”

Thanks to single embryo transfer and powerful, non-invasive genetic screening techniques, the structure and long-term prospects for health for modern IVF children are no different from those of anyone else.

Bottom line

IVF has now become a staple of reproductive medicine, with more than 100,000 children born by IVF every year in the United States alone. The multi-step process requires mechanical precision to locate chromosomally healthy embryos, which can then be transferred, and the success rate is up to 80% for patients under 40 after three full cycles. With a full grasp of the biological stages, early recognition and management of potential risks such as OHSS and the guidance of a registered reproductive endocrinologist, families can approach their fertility journey with clarity and confidence.

Frequently Asked Questions

Why are IVF babies usually boys?

There is a tiny statistical variation in which IVF cycles using blastocyst-stage frozen embryo transfers result in slightly more male births, which researchers believe is due to male embryos occasionally growing slightly faster in laboratory culture fluid.

How many IVF babies are born a year?

In the United States alone, more than 100,000 babies are now successfully born through in vitro fertilization every year, representing approximately 3% of the nation’s total annual births.
