California now requires many state-regulated large employer health plans to cover infertility care, including IVF, starting January 1, 2026.

California IVF & Infertility Coverage — DMHC Implementation Guidance (January 2026)

Summary: Beginning January 1, 2026, California requires many state-regulated large employer health insurance plans to cover infertility care, including IVF, and the Department of Managed Health Care has issued official guidance explaining how insurers must follow this law. The guidance confirms that eligible plans must cover fertility evaluations, medications, and IVF procedures under standard benefit rules and must apply an inclusive definition of infertility that protects LGBTQ+ individuals and single parents. While the mandate does not apply to self-funded employer plans, it significantly expands access to fertility treatment for many Californians by ensuring that infertility care is treated like other medical conditions under covered health plans.

Infertility is not only a medical issue; financial, emotional, and logistical factors strongly influence outcomes.

Family planning of infertile couples: a systematic review of intentions regarding parenthood and return to ART(December 2025)

Summary: Researchers reviewing studies of infertile couples found that many people end up having fewer children than they originally hoped. The reasons are often complex and include the high cost of treatment, the physical and emotional stress of IVF, delays in starting treatment, and uncertainty about success rates. The study highlights that infertility affects life planning and family goals, not just the ability to conceive in a single cycle, and that better support and access to care could help more people reach their desired family size.

Male infertility contributes to about half of infertility cases, and evaluation of both partners is important.

Impact of sperm DNA fragmentation index on assisted reproductive outcomes: (November 2025)

Summary: A large study of more than 5,000 couples undergoing IVF looked at whether sperm DNA fragmentation—a measure of damage to the genetic material inside sperm—affects fertility outcomes. The researchers found that higher DNA damage was linked to poorer semen quality and slightly lower embryo development rates, but it did not significantly reduce pregnancy or live-birth rates in IVF. However, babies conceived when sperm DNA damage was high had a somewhat higher risk of low birth weight, and the authors concluded that sperm DNA fragmentation may influence embryo development and some newborn outcomes, but its role as a reliable predictor of IVF success is still uncertain and needs more research.

The Age‐Related Risk of IVF Failure at an Advanced Age

When to Choose In Vitro Fertilization (IVF) When Postponing Conceiving:(October 2025)

Summary: This study reinforces that female age is the strongest determinant of IVF success, with a measurable inflection around age 35–36, after which live birth rates decline more rapidly—particularly between 35 and 40. While IVF can still be effective, the probability of success decreases each year, and counseling should reflect realistic expectations when patients delay treatment.

Research develops proof of concept for treatment of infertility affecting millions

OHSU Researchers Develop Functional Eggs from Human Skin Cells (September 2025)

Summary: OHSU researchers have shown that it’s possible to create early egg-like cells using the DNA from a person’s skin cell. They did this by inserting a skin-cell nucleus into a donated egg whose own DNA had been removed, then fertilizing it with sperm. A small number developed into early embryos, but most stopped growing and had chromosome problems, meaning the technique is far from ready for medical use. Scientists say the work is an early proof of concept that could one day help people who can’t produce eggs, but it will require many years of research before it could be considered safe.

Smart fertility benefits boost outcomes, cut costs, and strengthen workplace loyalty.

The Impact of Health Benefit Design on Patients With Infertility (August 2025)

Summary: This article explains that when health insurance covers infertility care, patients have a much better chance of getting the right treatments, becoming pregnant, and avoiding unnecessary stress or costs. Good benefit design also helps make fertility medicines easier to get and more affordable. For patients, this means clearer options, stronger support from employers, and better overall care on the journey to building a family.

Quest to create viable human sex cells in lab progressing rapidly, with huge implications for reproduction.

Lab-grown sperm and eggs just a few years away, scientists say (July 2025)

Summary: Lab-grown sperm and eggs—created through a process called in‑vitro gametogenesis (IVG), which transforms adult skin or blood cells into stem cells and then into germ cells within organ-like structures—could become clinically viable in as little as 5–10 years, potentially revolutionizing reproductive options for infertile individuals, same‑sex couples, and older parents, while also raising serious safety and ethical concerns that demand careful regulation.

Columbia University’s STAR AI system identified viable sperm from azoospermic men far faster and less invasively than current methods.

AI finds sperm in "infertile" men in under an hour (June 2025)

Summary: Researchers tested an artificial intelligence (AI) tool to help find rare sperm in infertile men with a condition called azoospermia. The AI was much faster and slightly more accurate than human experts at spotting sperm in lab samples. When used together with an embryologist, the AI also helped reduce the time needed to search for sperm. This technology could make infertility treatments quicker and more effective for men with very low sperm counts.

A global review of over 1,400 RCTs in infertility revealed inconsistent outcome reporting. Experts call for a universal outcome framework.

Infertility clinical trial review calls for outcome standards (May 2025)

Summary: This study looked at over 1,400 infertility trials published from 2012 to 2023. Most of the research focused on IVF and came from just a few countries, mainly China, Iran, and Egypt. Many trials didn’t clearly state their main goals or weren’t officially registered. While reporting has improved in recent years, the study shows a need for better research practices and a wider focus beyond just IVF.

Deep learning model using multi-modal data (video, clinical, genomic) to predict embryo viability and IVF success.

Multi‑Modal AI for Embryo Grading & Pregnancy Prediction (May 2025)

Summary: Researchers recently reviewed how multi-modal artificial intelligence—which combines static images, time-lapse embryo videos, and clinical data—can improve embryo grading and pregnancy prediction in in vitro fertilization (IVF), addressing key issues like subjectivity and data silos. This AI approach offers advantages such as standardization, efficiency, accuracy, cost reduction, personalization, and interpretability. While studies show promise, challenges remain around integrating diverse data types and obtaining enough high-quality datasets. As this tech matures, it could significantly enhance IVF success rates by helping clinicians select the healthiest embryos more reliably and consistently.

Gameto’s Fertilo helped achieve the first known live birth using stem cell-based oocyte maturation. A potential breakthrough in lowering hormonal side effects during IVF.

World’s first IVF live birth using stem cell-matured eggs (May 2025)

Summary: Gameto, a women's health company, has made history with the first baby born using Fertilo, a new fertility treatment developed from stem cell technology. Fertilo helps mature eggs outside the body, avoiding the need for heavy hormone treatments used in traditional IVF. This makes the process safer, less stressful, and potentially more affordable. The success shows hope for millions struggling with infertility, and Gameto plans to make Fertilo available in more countries soon.

Progesterone reduced inflammation and improved embryo development in mice.

Inflammation in reproductive tract linked to infertility; hormone therapy may help (May 2025)

Summary: Inflammation in the female reproductive tract—often driven by low progesterone responsiveness—can disrupt embryo development and make early pregnancy much less likely, with over 60% of pregnancy losses occurring in the first few weeks; importantly, a mouse study showed that treating this inflammation improved embryo survival and implantation, pointing to promising hormone-based or anti-inflammatory therapies that could one day help women with conditions like pelvic inflammatory disease or low progesterone conceive more successfully.

A major new study brings great news for expecting parents: receiving a COVID-19 vaccine during early pregnancy does not increase the risk of birth defects.

COVID-19 Vaccines During Pregnancy Are Not Linked to Birth Defects, Study Finds (April, 2025)

Summary: A large study looked at whether getting a COVID-19 vaccine early in pregnancy increases the risk of serious birth defects in babies. After reviewing over 78,000 pregnancies, researchers found no increased risk of major birth defects in those who were vaccinated. The results were the same regardless of the vaccine brand (Moderna or Pfizer), insurance type, or whether the mother had a COVID-19 infection. This supports the safety of COVID-19 vaccination during early pregnancy.

Reviews the therapeutic role of stem cells in infertility treatment and associated legal/regulatory gaps.

Stem Cells and Infertility: A Review of Clinical Applications and Legal Frameworks (April, 2025)

Summary: A recent review highlights the growing promise—and remaining challenges—of using stem cells to treat infertility, particularly for couples unable to benefit from conventional assisted reproductive technologies (ART). Researchers have explored various stem cell types—embryonic, induced pluripotent, mesenchymal, ovarian, and spermatogonial—with encouraging results in restoring ovarian function or sperm production; however, ethical concerns (especially around embryonic stem cells) and immunological risks persist. The study also outlines diverse legal and regulatory frameworks across six major European countries, underscoring the need for unified, evidence-based guidelines and ethical standards to ensure patient rights and safety as this treatment frontier advances.

Systematic review of evidence showing weight loss (especially GLP‑1 drugs) improves fertility in both sexes.

Summary: Losing weight through medically supervised treatments can help improve fertility in both women and men. This review found that weight loss—especially using medications like metformin or newer drugs such as GLP-1 receptor agonists—can restore hormone balance, improve menstrual cycles and ovulation in women, and boost sperm quality and sexual health in men. Even modest weight loss can make a big difference. While newer medications show promise, they should be used with caution if pregnancy is planned, as more research is needed on their safety during conception and pregnancy.

Infertility Improvement after Medical Weight Loss in Women and Men: (March, 2025)

Doctors at the University of Pittsburgh successfully transplanted frozen stem cells into the testes of a cancer survivor, offering future hope for restoring fertility.

Summary: Doctors performed the first-ever transplant of a man's own sperm stem cells, collected when he was a child before cancer treatment. The goal is to restart sperm production and restore fertility. Early results show the procedure is safe, though it's unclear if it will lead to sperm. This gives hope to young cancer patients who may want children in the future.

Sperm Stem Cells Were Used for the First Time in an Attempt to Restore Fertility (March, 2025)

Predictive model showing female infertility trends globally, with implications for public health planning.

Summary: A recent analysis using Global Burden of Disease data found that the worldwide impact of female infertility—measured in lost years of healthy life—is projected to climb significantly from 2021 to 2040, nearly doubling its annual growth rate from 0.7% to 1.4%. Though infertility rates are expected to decline slightly within age groups, overall age‑standardized disability rates will rise, with the heaviest burdens concentrated in Central Sub‑Saharan Africa and South Asia. Regions with higher socioeconomic development see lower infertility burdens, suggesting that targeted health policies, improved fertility services, and better access to care could help address this growing global concern.

Global infertility burden: 1990–2040 analysis (March, 2025)

Yale scientists found a naturally occurring antibody (OBF13) that blocks sperm–egg fusion via the IZUMO1–JUNO interaction, offering insight into infertility and potential non-hormonal contraception.

Yale discovers fertility-blocking antibody (March, 2025)

Summary: Yale researchers discovered how a natural antibody, called OBF13, can block sperm from fertilizing an egg by interfering with a key sperm protein (IZUMO1). This finding, made in rodents, could help develop new fertility treatments or non-hormonal contraceptives. It shows how the body can naturally prevent fertilization and opens new doors for both infertility and birth control research.

Highlights how poor diet and oxidative stress reduce fertility; Mediterranean diet shows promise.

1 in 6 Face Infertility: Is Nutrition the Missing Link? (March, 2025 )

Summary: About 1 in 6 people worldwide face infertility, and growing evidence suggests that poor nutrition and obesity—especially in men—play a significant role. Diets high in processed foods and low in key nutrients can lead to hormonal imbalances, inflammation, and sperm damage, while healthier patterns like the Mediterranean diet may improve fertility outcomes. New tools, like AI-based nutrient scoring systems, are helping identify specific deficiencies linked to infertility, though more research is needed. In the meantime, maintaining a healthy weight, eating a balanced diet, and considering targeted supplements under medical guidance may boost the chances of conception.

A randomized trial found that positive-thinking counseling plus cognitive reconstruction significantly reduced perceived stress in women with recurrent failed IVF cycles.

Stress management intervention during IVF (February, 2025)

Summary: In this study, women who had experienced multiple unsuccessful IVF cycles were randomly assigned to either routine care or a structured counseling program focused on positive thinking and reframing stressful thoughts. The counseling group completed multiple sessions and, by the day of embryo transfer, reported significantly lower stress levels compared with the control group. The takeaway for patients is that structured psychological support can meaningfully reduce distress during IVF and may be a helpful add-on for coping—especially after repeated setbacks.

A study found that taking the probiotic Ligilactobacillus salivarius (Fertibiome®) may influence the reproductive microbiome in women undergoing their first IVF cycle.

Probiotic Ligilactobacillus salivarius and IVF Outcomes (January 2025)

Summary: In this study of nearly 700 women undergoing their first IVF treatment, researchers investigated whether adding a specific probiotic (Ligilactobacillus salivarius PS11610) to the treatment protocol influenced pregnancy outcomes. Participants were compared across periods without and with probiotic supplementation. While fertility treatment success depends on many factors, the results suggest that probiotics may help shape the microbial environment in ways that support implantation and pregnancy. Although this type of intervention is still experimental, it highlights a growing area of research into how the reproductive microbiome might be linked with IVF success.

California passed SB 729, requiring fully insured large group health plans to cover infertility diagnosis and treatment, including in vitro fertilization (IVF), for insurance contracts issued, amended, or renewed on or after July 1, 2025. The law broadens the definition of infertility and ensures coverage is provided without discrimination based on age, gender, marital status, or sexual orientation. There is discussion about potentially moving the effective date to January 1, 2026, to allow for insurance plan updates.
