Can oxidative stress in embryo culture medium predict pregnancy?
In 101 couples, culture-medium oxidative-stress markers differed by embryo stage but did not independently predict clinical pregnancy.

Freeze-all or fresh transfer? A study of 2,102 low-prognosis women
Adjusted cumulative live birth was 46.7% with a fresh-transfer strategy versus 40.0% with freeze-all. Observational findings support individualized decisions.
-
Progesterone-based timing for natural-cycle frozen embryo transfer
Researchers studied transfer two days after progesterone reached 5 ng/mL. The approach remains under evaluation; better live-birth outcomes are not established.

Frozen embryo transfer: AI identifies seven pregnancy predictors
An analysis of 4,300 euploid transfers identified seven pregnancy predictors. Learn what an AUC of 0.778 means and why it is not a pregnancy rate.
-
Proteins released by embryos offer clues to chromosome status
A laboratory study of 69 human embryos found chromosome-related differences in secreted proteins. Learn why the day-10 findings are not a clinical selection test.
-
Is there a special fertility diet? What a study of 2,370 couples found
A study of 2,370 couples examined diet and live birth during fertility treatment. Learn why no single dietary pattern emerged as a special fertility diet.

Why can endometriosis pain persist after lesions are removed? A mouse study examines fibrosis
A mouse study links persistent endometriosis-related pain with fibrosis and pelvic adhesions after lesion removal. Learn what it can and cannot tell us.

Does endometrial compaction predict pregnancy? Findings from 207 euploid embryo transfers
A prospective study of 207 euploid embryo transfers found no clear pregnancy advantage with endometrial compaction. Read the findings and their limits.

Why does implantation fail? A 3D human model reveals embryo–endometrial dialogue
A 3D human embryo–endometrium model reveals signals involved in implantation. Explore what the findings mean—and why they do not yet establish a treatment.

Egg-freezing triggers: what 325 fertility-preservation cycles showed
A 325-cycle study compared GnRH agonist and dual triggers. Egg yields differed, but trigger type was not independently significant after adjustment.

Repeat surgery after ovarian endometriosis: a 13,912-woman follow-up study
A Finnish study of 13,912 women estimated 17.3% reoperation risk over 30 years after ovarian endometriosis surgery, with implications for fertility planning.

Embryo oxygen consumption: a microchip explores a new way to assess blastocysts
A microchip measured oxygen use in 17 mouse and 42 human blastocysts. Mouse hatching findings do not establish improved human pregnancy outcomes.
