[Effect of blood concentrations of preovulatory estradiol on the quality of eggs and pre-embryos in patients treated with fertilization in vitro].

The objective was to investigate if the preovulatory estradiol concentrations obtained during controlled ovarian hyperstimulation (COH) have effect on reproductive outcome. The study included a total of 198 in vitro fertilization (IVF) cycles. Patients were divided into four groups according to serum preovulatory estradiol concentrations.

[Changes in preovulatory molecular relationship between estradiol and progesterone in patients undergoing controlled ovarian hyperstimulation. Can they be used for the evaluation of ovarian reserve?].

The objective was to evaluate if the preovulatory molecular ratio between progesterone and estradiol has age-dependent changes in patients undergone controlled ovarian hyperstimulation. Were studied 180 cycles of conventional in vitro fertilization. Patients were divided in three groups: Group 1 (age less than 30 years; n = 40), group 2 (age between 30 and 35 years; n = 82), and group 3 (age between 36 and 40 years; n = 58).

[Changes in preovulatory molecular progesterone/estradiol ratio in patients treated with controlled ovarian hyperstimulation. Can they be used in the assessment of ovarian reserve?].

The objective was to evaluate if the preovulatory molecular ratio between progesterone and estradiol has age-dependent changes in patients undergoing controlled ovarian hyperstimulation. There were 180 cycles of conventional in vitro fertilization which were studied. Patients were divided in three groups: Group 1 (age less than 30 years; n = 40), group 2 (age between 30 and 35 years; n = 82), and group 3 (age between 36 and 40 years; n = 58).

[Methods of pedicle hemostasis in laparoscopically-assisted vaginal hysterectomy (VAVH). Evaluation of results].

The objective was to evaluate whether use of different techniques of hemostasia have effect on laparoscopically assisted vaginal hysterectomy (LAVH) morbidity. Was performed a review of 53 LAVH cases, parameters analyzed were type of hemostasia method and surgical complications. There were five patients with transoperative bleeding and two with incidental bladder lesion, that were managed successfully without complications.

[Effect of intrafollicular interleukin-6 levels on the secretion of estradiol and progesterone in patients treated with in vitro fertilization and embryo transfer].

The objective was to evaluate the relationship between follicular fluid levels of Interleukin-6 (IL-6) and the seric concentrations of estradiol and progesterone during controlled ovarian hyper-stimulation. The levels of IL-6 were measured in follicular fluid of 15 patients undergone to in vitro fertilization and embryo transfer and correlated with the values of seric estradiol and progesterone. There were a negative correlation between follicular levels of IL-6 and either estradiol and progesterone.
