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.

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.

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.
