Reports are listed according to publication date. The post-fertilization ages, proposed by the authors of the reports, were estimated as follows: RH = calculation according to the Reichert-His convention; IM = calculations according to diverse concepts of intermenstrual ovulation; MC = calculations according to the concept of mid-cycle ovulation; C = coital age; St = estimations according to Streeter (matching with macaque embryos]. Abbreviations: fertil. = fertilization; gest. = gestational; info. = information.
