Stage of fetal development that lasts from day 15 until approximately 8 weeks after conception or until the embryo measures 3 cm from crown to rump
Uniting of the sperm and ovum, which occurs within 12 hours of ovulation and within 2-3 days of insemination, the average duration of viability for the ovum and sperm

Coordinated sequence of involuntary uterine contractions resulting in effacement and dilation of cervix, followed by expulsion of the fetus/neonate
the ratio of two components of amniotic fluid, used for predicting fetal lung maturity
