title: Study of luteal function.
abstract: On studying various parameters of luteal function, the authors demonstrated that BTT does not permit the evaluation of luteal phase defects, whereas the E.I. and prolactin levels, as well as the endometrial biopsy, may be considered valid parameters. The TRH test is more efficient than basal prolactin evaluation in this respect. Progesterone should be evaluated in various moments of the luteal phase and not by a single determination. The authors conclude that the abnormal luteal phase is the result of an abnormal follicular maturation and that the central origin of this mechanism may be affirmed.
