title: [Multifactorial analysis of the blood levels of LH, FSH and estradiol in relation to ovular harvesting rates, fertilization and segmentation in patients undergoing assisted reproduction (GIFT-FIVTE)].
abstract: This study shows that there is certain tendency to asssign more value to the observation of follicular growth by ultrasound than to hormonal levels "per se". However, the appreciation of growth is only part of the phenomenon of development and ovarian maturity, for that, surveillance with hormonal monitor of ovarian response keeps with a most important role in Assisted Reproduction Clinica. The basal levels, mainly of FSH and in a less degree LH, inversely correlate with the amount of retrieved ovocytes. Estradiol values should be interpreted with a fixed point of reference, as the day of HCG administration, and a direct relation is seen between estradiol levels and captured ovocytes; however, is of highest usefulness to value the conduct of estradiol level, with the knowledge that the prognosis for good capture rates improves with ascending values and above 700 pg in the day of HCG administration.
