The transfer of blastocysts obtained by co-culture with 'Vero' (African green monkey kidney) cells was offered to infertile couples with the following indications: (i) repeated failure of implantation, (ii) patients in whom multiple pregnancies had to be avoided (malformed uterus or risk of descending uterus), (iii) patients where embryo development(More)
INTRODUCTION Although physiotherapy is an integral part of the multiprofessional team in most ICUs there is only limited evidence concerning the effectiveness of its procedures. The objectives of this study were to verify if physiotherapy care provided within 24 h/day for hospitalized patients in the ICU reduce the length of stay, mechanical ventilation(More)
Human interleukin for DA cells/leukaemia inhibitory factor (HILDA/LIF) is a cytokine with pleiotropic effects involved in successful murine implantation. We evaluated human uterine HILDA/LIF production by monitoring its in-vitro secretion by endometrial explant cultures obtained from individuals in either normal or pathological conditions. The cytokine(More)
The recent development of co-culture technique has permitted to cryopreserve human embryos at the blastocyst stage. The aim of the present study was to compare pregnancy rates after transfers of embryos frozen at an early embryo stage (2-8 cell stage, group A; n = 175) with others frozen at blastocyst stage (group B; n = 98). Our results demonstrated that(More)
Coculture techniques on monolayers cells increase the rate of human blastocysts development. The selection of these heavier and more expensive methods should be reserved for cases which this work specifies. The rate of achieved pregnancies seems increased, embryo quality being, at this stage of later development, better estimated, from which a more(More)
Contraceptive techniques that selectively impair endometrium receptivity have the potential to reduce the risk of cardiovascular complications associated with hormonal methods. However, further research is needed to provide better treatment when oral estrogen is contraindicated, to improve tolerance of progestin-only contraceptives, and identify(More)
OBJECTIVE To determine the implantation rates of cryopreserved blastocysts using controlled E2 and P replacement cycles in women with functioning ovaries. DESIGN Retrospective clinical study. SETTING University teaching hospital. PATIENTS Infertile women with cryopreserved blastocysts obtained from previous IVF attempts. INTERVENTIONS Exogenous E2(More)
We report a prospective trial of in vitro sperm-mucus penetration test performed in hormonally controlled environment. To enhance the quality of the cervical mucus (CM), prevent spontaneous ovulation and to eliminate the possibility that results may be biased solely because of CM inadequacy, we conceived a 28-day physiological hormonal replacement regimen.(More)
