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.
Can you have sex before or after embryo transfer? This article reviews what fertility clinics recommend, summarizes the clinical studies, and explains whether sexual intercourse or seminal plasma may affect implantation and pregnancy rates after IVF.
Researchers in a 2026 study found that more than two-thirds of patients with complete embryo arrest still developed at least one usable blastocyst in their next IVF cycle, although they had lower usable blastocyst formation rates overall and were more likely to experience complete embryo arrest again.

Researchers combined the results of 86 randomized trials to evaluate ten of the most commonly used IVF add-ons and found that endometrial scratching improved the chance of having a baby, while most other add-ons showed little or no benefit or require more high-quality research.
Researchers in a 2026 meta-analysis combined the results of seven randomized trials and found that Lactobacillus-containing probiotics were associated with higher clinical pregnancy rates in women undergoing assisted reproductive technology, although important limitations make the results difficult to interpret.
Eight years, three miscarriages, and eight embryo transfers finally led to a healthy baby girl. In October 2025, Laura welcomed her daughter, Aubree.
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.
This post provides a short summary of select studies presented during the European Society of Human Reproduction and Embryology (ESHRE) 2026 meeting in London. These studies may not have been published or peer reviewed yet.
Researchers in a 2025 meta-analysis combined the results of 21 studies and found that microfluidic sperm selection improved embryo quality and slightly improved fertilization rates, but it didn’t significantly improve euploid, pregnancy, or live birth rates.
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.

Researchers in a 2026 study found that patients with only one fertilized egg (zygote) may have a higher chance of live birth with cleavage stage transfer than blastocyst stage transfer, especially at older ages.
Researchers in a 2026 study proposed statistical thresholds that may help distinguish between poor IVF results that can happen by chance and those that may need a closer look.
Researchers in a 2026 study found that about 0.4% of blastocysts derived from apparently normal 2PN fertilization were triploid, and although these embryos were more likely to have abnormal polar body extrusion, genetic testing is still the only reliable way to identify them.
Researchers in a 2026 study found that a single ultrasound performed at 45 days of IVF gestation may be sufficient to diagnose many miscarriages without the need for a repeat scan.
Researchers in a 2026 randomized controlled trial found that natural FETs using euploid embryos were associated with lower early pregnancy loss rates and higher live birth rates than medicated transfers, although the study was stopped early.
Researchers in a 2026 study found that higher beta-hCG levels measured 9 days after a single euploid embryo transfer were linked to a higher chance of live birth and a lower chance of biochemical pregnancy loss or ectopic pregnancy.

The ASRM published their 2026 guidelines on managing recurrent pregnancy loss (RPL), reviewing which tests and treatments are supported by evidence, which may be considered in certain situations, and which are not routinely recommended.
A 2026 study explored how IVF patients emotionally navigated the decision to transfer embryos labelled “abnormal” by PGT-A, with many describing grief, uncertainty, and loss of trust in the testing process.
A 2026 meta-analysis combined the results of 105 studies to examine the causes of recurrent pregnancy loss (RPL), finding that unexplained RPL and acquired thrombophilia were the most common.
A 2026 meta-analysis examined how well PGT-A biopsies represented the rest of the embryo, and found higher mismatch rates in embryos labeled as aneuploid, especially segmental aneuploid embryos.
Researchers in a 2026 study found that natural FETs using donor eggs were linked to higher live birth rates, lower miscarriage rates, and lower rates of some pregnancy complications compared to medicated FETs.
Six retrievals and seven embryo transfers were needed before a Day 6 4BB euploid embryo finally led to a healthy baby at age 40, after an early euploid rate of just 1 out of 17 embryos.
Aneuploid embryo success rates after transfer are very low, with about 1–2% leading to a live birth, likely due to undetected mosaicism after PGT-A rather than true whole chromosome aneuploidy.

Research in a 2026 study found that bacteria detected on the embryo transfer catheter were linked to lower live birth rates, likely reflecting the patient’s own microbiome being carried into the uterus during transfer.
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 study found that low β-hCG levels (≤50 mIU/mL at 9 days after blastocyst transfer) were linked to much lower live birth rates, and that how hCG rises over time is more predictive of outcome than the initial value.
