Uterine artery hemodynamic adaptations through the menstrual cycle into early pregnancy.

Objective: To estimate the time course of human uterine artery vascular adaptation through the menstrual cycle into early pregnancy.

Methods: We prospectively measured the uterine artery pulsatility index, peak systolic velocity, and volumetric blood flow during the menstrual cycle and at 4, 6, and 12 weeks of pregnancy in women who conceived. Upper extremity radial artery hemodynamic changes were examined as a control vessel.

Prediction of endometrial ablation success by preoperative findings.

Objective: To determine the influence of preoperative findings on the outcome of hysteroscopic endometrial ablation.Design: We performed a retrospective chart review of 80 women between the ages of 25 and 50 years who underwent an endometrial ablation for menorrhagia or menometrorrhagia from 1992 to 1996, through a university reproductive endocrinology clinic.Materials and Methods: All eligible patients had a detailed subjective history obtained for duration of dysmenorrhea (Dys) and menorrhagia or menometrorrhagia (Men).

Human motile sperm recovery after cryopreservation: freezing in nitrogen vapor vs the direct plunge technique.

Objectives: The following will be tested: 1) Freezing in nitrogen vapor prior to submerging will have a higher motile sperm recovery rate compared to directly submerging in liquid nitrogen, 2) The length of time a sample spends in nitrogen vapor will not affect the motile sperm recovery, and 3) The volume of sample to be frozen will not affect the recovery of motile sperm.Design: This is a prospective study performed through a university infertility clinic. The semen samples were obtained from 20 male partners of couples being screened for in vitro fertilization.

Prediction of endometrial ablation success according to perioperative findings.

Objective: The aim of this study was to determine which factors in the perioperative period influence the success of endometrial ablation in alleviating menorrhagia.

Study Design: We performed a retrospective chart review of 120 women aged 27 to 49 years who underwent endometrial ablation after 2 months of preoperative treatment with danazol (Danocrine, 800 mg/d orally) or leuprolide (Lupron, 3.75 mg in one intramuscular injection each month).

Regional hemodynamic adaptation during the menstrual cycle.

Objective: To determine whether regional differences exist in uterine and systemic hemodynamic responses to the menstrual cycle, whether the hormonal environment correlates with the changes, and whether uterine artery hemodynamic adaptation depends on the side of ovulation.

Methods: Twenty nulliparas had transvaginal Doppler ultrasonographic assessment of the uterine and upper-extremity radial arteries at three time points in each of two menstrual cycles. Doppler indices (peak systolic velocity, end-diastolic velocity, time-averaged maximum velocity, resistance index [RI], and blood flow) were measured in the radial and uterine arteries.

Delayed delivery of a triplet pregnancy without surgical intervention: a case report.

Multiple gestations have a significantly increased incidence of preterm labor and preterm rupture of membranes. This leads to an increase in neonatal morbidity and mortality due to prematurity. In this case, a 30-year-old woman achieved a triplet pregnancy by ovulation induction and intrauterine inseminations.

High success with gestational carriers and oocyte donors using synchronized cycles.

Purpose: Our purpose was to determine if exogenous hormone stimulation of the endometrium improves the implantation and pregnancy rate with a host uterus or gestational carrier.

Results: Nine couples underwent 14 embryo transfer cycles with a gestational carrier. The median age was 31.
