One-Step Embryo Warming: 10 Minutes Cut to 1, With 97.7% Survival
A UK study of 3,887 blastocysts found 97.7% survival after one-step warming, with no significant improvement in pregnancy or live birth rates.

Day 7 Euploid Embryos: A 24.1% Live Birth Rate, Not a Lost Cause
Can day 7 embryos lead to a baby? A study of 3,338 euploid frozen embryo transfers found lower live birth rates, but meaningful potential for D7 embryos.

Sleep and Fertility: Sperm Quality, Implantation and IVF Outcomes
Studies link sleep quality and breathing disorders with semen measures and IVF outcomes. Understand the evidence without confusing association with causation.
-
Pregnancy and Biological Aging: Can the Clock Reverse After Birth?
Pregnancy can increase some epigenetic age measures, while postpartum recovery may reverse them. Explore the evidence, parity findings and limitations.

Fluid in the Uterus Before FET: What It Means for Live Birth
Fluid during frozen embryo transfer preparation was linked to lower live birth rates. Size and cause matter, but 2.55 mm is not a cancellation rule.

FMR1 Premutation and IVF: Fewer Eggs, Similar Embryo Euploidy
FMR1 premutation carriers may retrieve fewer eggs without lower euploidy among tested blastocysts. Explore the IVF study, genetics and key limitations.
-
Blastocyst Collapse in IVF: What Does It Mean for Pregnancy?
A time-lapse study links blastocyst collapse and cytoplasmic strings with embryo quality and early pregnancy. Learn the findings and their limitations.
-
Non-Invasive PGT-A in IVF: What Culture-Medium DNA May Reveal
Early IVF research examines DNA fragment patterns in culture medium for clues to embryo chromosomes. Learn what it found and why biopsy remains standard.
-
Low AMH and Egg Quality: What an FMR1 IVF Study Found
FMR1 premutation carriers produced fewer eggs, but the chromosome-normal rate per biopsied blastocyst was comparable with matched controls. The findings do not apply to every cause of low AMH or every aspect of egg quality.
-
IVF With Diabetes, Hypertension or Obesity: Live Birth Evidence
Studies link type 2 diabetes, hypertension and obesity with lower live-birth outcomes after assisted reproduction. Findings differ for type 1 diabetes and hypothyroidism, making preconception health assessment important.
-
Embryo Fragmentation in IVF: What the DEBRIS Trial Will Test
The DEBRIS trial will test whether removing cytoplasmic fragments from day-4 embryos improves blastocyst development and pregnancy outcomes. It is recruiting, with no results posted.

PRP for Recurrent Implantation Failure: New Live Birth Data
A study of 230 women with recurrent implantation failure and endometrial thickness above 7 mm found live birth rates of 45.5% with PRP and 30.0% without it. Patient-selected treatment limits causal conclusions.
