Our goal was to study cancer incidence among a cohort of women treated with IVF, including ICSI and frozen embryo transfer (FET), compared with that of a control population. METHODS A cohort of women who purchased drugs for IVF (including ICSI(More)
BACKGROUND The frequency and importance of complications of IVF and other ovulation induction (OI) are poorly known. We examined the occurrence of serious complications and miscarriages leading to hospitalization or operation after IVF (including microinjections and frozen embryo transfers) and OI treatment (with or without insemination). METHODS Women(More)

METHODS Data were from the Finnish Medical Birth Register for periods 1991-1993 and 1998-1999. Outcomes of IVF infants and other infants were compared, both overall and separately for singleton and multiple(More)

OBJECTIVE To examine the incidence of cardiovascular diseases and cancer from published clinical trials that studied other outcomes of postmenopausal hormone therapy as some surveys have suggested that it may decrease the incidence of cardiovascular diseases and increase the incidence of hormone dependent cancers. DESIGN Trials that compared hormone(More)

Changes have also occurred in maternity care,(More)
