Childbearing in women diagnosed with cancer during reproductive age

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
Compared to cancer‐free women, the probability of childbearing within 5 years of a cancer diagnosis was reduced, particularly among those diagnosed over the age of 30. Age at diagnosis and antineoplastic treatment were key factors, with treatment also increasing the use of assisted reproduction. Abstract Introduction Fertility after cancer represents a

Impact of double versus single blastocyst biopsy and vitrification on clinical and neonatal outcomes in PGT cycles: A systematic review and meta‐analysis of embryo retesting

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
Rebiopsied and revitrified blastocysts may be linked to lower pregnancy and live birth rates in single euploid frozen embryo transfer cycles (very low‐quality evidence). Subgroup effects by biopsy day and morphology may hold clinical relevance and guide future study design.

Perinatal outcomes in pregnancies with very and extremely advanced maternal age: An Italian multicenter retrospective cohort study

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
Assisted reproduction in women aged ≥45 years increases maternal risks, particularly with donor oocytes, while neonatal outcomes remain unaffected. These findings highlight the importance of personalized counseling and care strategies in very advanced maternal age pregnancies.

The threshold of estradiol level for fresh embryo transfer differs between blastocyst and cleavage‐stage embryo

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
Our results suggested that the difference in pregnancy outcomes between fresh and frozen embryo transfer is related to the peak estradiol level and embryo transfer stage. The cutoff values for peak estradiol level for performing freeze‐all strategy to improve pregnancy outcomes were different for cleavage‐stage and blastocyst‐stage embryo transfer ...
