Most long-term health outcomes appear similar between children conceived through IVF and those conceived without fertility treatment. A few small differences have been reported, but some may be related to the parents’ underlying infertility rather than the fertility treatment itself.
Researchers in a 2026 meta-analysis combined the results of 9 studies and found that embryos from 0PN zygotes had similar pregnancy outcomes to embryos from normally fertilized (2PN) zygotes, despite being less likely to develop into blastocysts.
Researchers in a 2026 meta-analysis combined the results of 11 randomized trials and found that natural FETs were associated with slightly higher live birth rates and lower miscarriage rates than medicated FETs in women who ovulate regularly.
A 2026 study found that infertility is traumatic for some patients, with 9% meeting criteria for PTSD and 32% for complex PTSD, and patient narratives highlight distress, loss of control, and gaps in care.
A 2026 meta-analysis explored ways to optimize natural FETs, examining ovulation timing, progesterone use, luteinized unruptured follicles, and cycle variability across natural, modified natural, and newer natural proliferative phase approaches.
Researchers in a 2026 guideline review provide evidence-based recommendations from ESHRE on ovarian stimulation for IVF/ICSI, covering protocols, medications, monitoring, and safety.
A 2026 study of over 227,000 IVF couples found that chromosomal abnormalities were uncommon but more frequent than in the general population, and were most strongly linked to recurrent miscarriage, poor sperm quality, and younger age.
A 2026 study found that a microfluidic device called FIND-Chip can recover additional eggs from follicular fluid that may have been missed by manual searching after an egg retrieval, with one live birth reported.
A 2026 randomized trial found that natural FETs had similar healthy live birth rates to medicated FETs, but were linked to lower risks of preeclampsia, pregnancy loss, and some other pregnancy complications.
A 2026 study found that switching frozen embryo transfer protocols after a failed transfer did not improve live birth compared with repeating the same protocol, including in PGT-A cycles, with some small and uncertain differences seen in specific natural FET types.
A 2025 study found that after a first frozen embryo transfer, experiencing an early pregnancy loss did not increase the risk of loss in the next transfer, for both euploid or untested embryos.
Researchers in a 2025 study showed that women with endometriosis or adenomyosis had lower IVF success overall after 3 IVF cycles, with more differences in the first, fresh transfer.
A 2025 case report describes two IVF patients who conceived triplets from a single embryo transfer and offers insight into just how rare this is.
This post explains how embryos can split during IVF, especially at the blastocyst stage. It covers the timing of splitting, the different types of identical twins, the factors that make splitting more likely, and how IVF labs can reduce the risk of twins after single embryo transfer.
A new study found that selecting FSH type based on a woman’s FSH receptor (FSHR) genotype may improve IVF pregnancy and live birth rates, particularly when using rFSH for NN genotypes and uFSH for NS or SS genotypes.
A 2024 study combined the results of 14 studies analyzing how hysteroscopy impacts IVF success, finding improvements in live birth rate, pregnancy rate and no change in miscarriage rate.
A 2024 study found that working past 4 pm, specific procedures, and variability among embryologists all contribute to errors in IVF labs.
The ASRM published their 2024 guidelines on cancer and fertility drugs, offering an overview of the latest research on whether fertility drugs raise the risk of cancer.
A 2024 study compared IVF outcomes and pregnancy rates for patients of different ages (<32 to >40) who had their first single embryo transfer.
A 2024 study combined studies involving unexplained infertility patients and endometriosis, finding that nearly half of them have the condition.
After a failed first IVF cycle, researchers found that switching ovarian stimulation protocols was linked to a reduced chance of another cancellation, with factors like age, diagnosis and smoking status also contributing to success.
