The microscopic pattern of the endometrium during the last 14 days (postovulatory or progestational phase) of any menstrual cycle follows a regular identifiable histologic sequence of events. The "dating" for each of these postovulatory days conirms to what is termed a “standard cycle" with ovulation on day 14 and menstruation on day 28. Coital date reported from memory, accuracy questionable? This ovum was fixed in acetone for histochemistry (see MSS. page 448) and has not been given an accession number at the Carnegie Laboratory. Because of the different fixation technique, its measurements are not included in table 3. In a few instances where the catamenial history was insufficient, the range in onset of catamenia was widened arbitrarily afford a longer potential ovulation time. Catamenia or a period "Periods are 28 days apart." Obviously this patient ovulated somewhat earlier than the EOT of 13-17 in order to have roduced a 17-day ovum on day 28 of the cycle. Therefore she must have ovulated about day 11.
