‘ Probable day of ovulation is at best an estimate based upon (a) the apparent developmental age of ovum, b) the interpretation of the degree of progestational change of the endometrium and (c) the clinical history. ‘Of the coital dates recorded by the patient the one given is most likely to have resulted in the pregnancy ere described.

A well isolated or single, and therefore, critical coital date. 3 Estimated ovulation time is based on the fact that the modal time of ovulation is 14 1- 2 days before the ext expected period, as follows:

25-32, range in onset of catamenia 16-12, range in ovulation

9-20, E.O.T. in this patient Abnormal fertilized ova of about 3-14 days of development

‘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 conforms to what is termed a “standard cycle” with ovulation on day 14 and menstruation on day 28.
