Women in ART treatment due to male or tubal factor will be included. The day 3 hormone level (E2, progesterone, FSH, LH, TSH, prolactin, inhibin A, inhibin B and activin) and blood pressure will be measured one month before ART treatment. After gonadotropin administration, all the hormone and blood pressure changes will be measured and recorded at day 3, day 7 and the day before hCG injection as well as the day of oocyte retrieval. All biophysical and biochemical characteristics will continue to follow up on the 15th day after embryo transfer and to the end of the first trimester in the pregnancy group.
