Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

Experimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Long‐term child outcomes after prenatal aspirin exposure: A 4‐year follow‐up of a randomized controlled trial (the APRIL study)

International Journal of Gynecology &Obstetrics, Volume 173, Issue 1, Page 302-311, April 2026.
Abstract Objective To identify the long‐term child outcomes after prenatal aspirin exposure. Methods This study is a follow‐up of a randomized controlled trial (RCT) evaluating low‐dose aspirin in the prevention of recurrent spontaneous preterm labor (the APRIL study) comparing aspirin 80 mg daily (n = 194) to placebo (n = 193) in singletons.

Oocyte activation: The impact of calcium signals on fertilization [PDF]

, 2008
Fertilization is triggered by changes in intracellular calcium concentration. In mammals, these transients in ooplasmic calcium concentration take the form of repetitive spikes, so called calcium oscillations (Ca2+-oscillations).

IGF‐1 Deficiency Serves as an Integrated Biomarker Pathogenic Driver and Predictor in Poor Ovarian Response

Advanced Science, Volume 13, Issue 18, 27 March 2026.
IGF‐1 deficiency underlies poor ovarian response (POR), as reduced levels in follicular fluid and granulosa cells impair antral follicle formation and compromise reproductive outcomes. Including IGF‐1 as a biomarker significantly enhances the accuracy of models predicting both PORrisk and pregnancy success.

Intracytoplasmic sperm injection.

Tidsskrift for den Norske laegeforening : tidsskrift for praktisk medicin, ny raekke, 1998
The first results of intracytoplasmic sperm injection (ICSI) in Norway are presented. Acceptable fertilization rates were obtained for all indications; severe male infertility, as well as moderately reduced sperm quality where in vitro fertilization (IVF) and embryo transfer had previously failed.
