Implicaţiile progesteronului în obţinerea sarcinilor prin fertilizare in vitro

Background. The evaluation of the second day progesterone ‘s importance regarding the starting of the IVF cycle and it’s correlation with biochemical and clinical pregnancies. Methods. A retrospective study in which we use 2 groups of patients matched by age, hormonal status and infertility pathology. In the first group we used short agonist protocol that started only if second day progesterone was lower than 0,6ng/ml and for the second group we started the stimulation without measuring the progesterone levels. Results. Higher pregnancy rate for the first group. Conclusions. Low progesterone values in the second day of the cycle apparently result in higher pregnancy rates when using agonist short protocols.
