Geminography: the crystallography of twins

The geometric theory of twinning was developed almost a century ago. Despite its age, it still represents the fundamental approach to the analysis and interpretation of twinned crystals, in both the direct and the reciprocal space...

Perinatal outcomes of spontaneous twins compared with twins conceived through intracytoplasmic sperm injection

Objective: To compare perinatal outcomes in spontaneous twins compared with those conceived by intracytoplasmic sperm injection (ICSI).

Design: Retrospective case-control study.

Patients: Cases consisted of 274 intracytoplasmic sperm injection twins, controls were 348 naturally conceived twins delivered between 1999 and 2003 in a tertiary hospital.

Main outcome measures: Birth weight, gestational age at birth, cesarean delivery rate, perinatal mortality and morbidity, congenital anomalies, gestational diabetes and pregnancy induced hypertension.

Results: Preterm deliveries (76.6% vs...
