AIM To compare donor and recipient outcome after inducing the final oocyte maturation with hCG or GnRH agonist in GnRH-antagonist treated oocyte donation (OD) cycles. METHODS Two-hundred fifty-seven oocyte donors were enrolled to participate in a clinical trial in a private fertility centre. After stimulation with 225 IU rFSH and Cetrorelix 0.25 mg/day,(More)
Background. Intensity of exercise and low energy consumption, specific type and amount of training, early age at initiation, previous menstrual dysfunctions, low body mass index (BMI) or percentage body fat, pathological feeding habits and psychological stress have been suggested as potential factors accountable for menstrual irregularities in female(More)
OBJECTIVE To analyze prognostic factors that are associated with a discordant outcome in egg recipients sharing oocytes from the same donor. DESIGN Matched case-control single-center study. SETTING Private infertility clinic. PATIENT(S) Four hundred forty-four recipients (222 pairs) sharing oocytes from the same donor and showing a discordant outcome.(More)
OBJECTIVE To compare pregnancy and implantation rates with transvaginal (TV) versus transabdominal (TA) ultrasound-guided embryo transfer (ET). DESIGN Randomized, clinical trial registered at (NCT 01137461). SETTING Private, infertility clinic. PATIENT(S) Three-hundred thirty randomized recipients of donor oocytes. INTERVENTION(S)(More)
INTRODUCTION Information is scarce regarding the outcome of oocyte donation (OD) in patients with a history of cancer treatment. Therefore, we conducted a matched controlled analysis on the outcome of OD in these recipients. METHODS Between January 2000 and November 2005, 33 patients with a history of chemotherapy and/or radiotherapy had an OD cycle.(More)
Raloxifene, a selective oestrogen receptor modulator, is effective in the treatment of osteoporosis without stimulating the breast and the endometrium. Although it is associated with a decrease of cardiovascular risk markers the effect of these changes on atherogenesis, is not clear. In this study, we aimed to investigate the effect of raloxifene on aorta(More)
OBJECTIVE To determine the prevalence of obesity and other cardiovascular risk factors (RF) in middle-aged women, to correlate them with each other, and to describe the prevalence of such a RF and their changes with aging, menopause and Hormone Replacement Therapy (HRT) in a cohort of Chilean workers. MATERIAL AND METHOD In 1991-1992 cardiovascular RFs(More)
BACKGROUND Tibolone is a synthetic steroid effective for the treatment of climacteric symptoms and osteoporosis. Long term treatment with tibolone is associated with a significant decrease in cholesterol levels due to a parallel decrease in high-density lipoprotein. However, the effect of these changes on atherogenesis is not known. OBJECTIVE To(More)
STUDY QUESTION How long is the individualized training and the stability of competence for the embryo transfer (ET) technique? SUMMARY ANSWER The embryo transfer technique is easy-to-learn, hardly unlearned, and training should be individualized by monitoring with learning curve-cumulative summation (LC-CUSUM) curves. WHAT IS KNOWN ALREADY Like many(More)
BACKGROUND Different hormonal replacement regimens are used for treating climacteric complaints; however, not all of them have the same clinical profile. Cardiovascular disease (CVD) is a major health problem and tibolone, raloxifene, estradiol (alone or with cyproterone acetate) have been added to cholesterol-fed rabbits to study atherosclerosis.
