OBJECTIVE To determine whether the transfer of blastocysts on day 5, developed in sequential culture media, resulted in an increase in implantation rate compared with embryos transferred on day 3. DESIGN Comparative study of embryo culture regimes. SETTING Private practice assisted reproductive technology center. PATIENT(S) Twenty-three patients(More)
OBJECTIVE To determine the relationship between blastocyst score and pregnancy outcome. DESIGN Retrospective review of blastocyst transfer in an IVF clinic. SETTING Private assisted reproductive technology unit. PATIENT(S) 107 patients undergoing blastocyst culture and transfer of two embryos. INTERVENTION(S) Culture of all pronucleate embryos in(More)
The effectiveness of blastocyst culture and transfer in human in-vitro fertilization (IVF) was evaluated in a prospective randomized trial in patients having a moderate to good response to gonadotrophin stimulation. Embryos were transferred either on day 3 after culture to around the 8-cell stage in Ham's F-10 medium supplemented with fetal cord serum, or(More)
The relationship of the circulating level of progesterone (P) on the day of human chorionic gonadotropin (hCG) injection to occurrence of clinical pregnancy was examined in 133 leuprolide acetate human menopausal gonadotropin (hMG) in vitro fertilization cycles in women having at least three embryos transferred. Progesterone concentrations greater than 0.5(More)
OBJECTIVE To determine whether previously described advanced blastocyst development and high implantation rates are confirmed in an expanded multicenter trial. DESIGN Retrospective review. SETTING Two private assisted reproductive technology units. PATIENT(S) One hundred seventy-four patients who underwent blastocyst culture and transfer. (More)
OBJECTIVE To assess the efficacy of a novel protocol-microdose GnRH agonist (GnRH-a), FSH, and GH, for the stimulation of IVF patients who were canceled previously on a standard luteal GnRH-a, FSH, GH protocol. DESIGN Prospective evaluation using the patient's previous IVF stimulation attempt as historic controls. SETTING Private practice assisted(More)
To assess the impact of assisted hatching on in vitro fertilization (IVF) outcome in women age 40 and older. A retrospective analysis was performed to compare 28 cycles of IVF without assisted hatching to 38 cycles of IVF with assisted hatching. All patients in both groups were age 40 or older and the mean age was similar. The delivery rate per oocyte(More)
Oocyte vitrification has the potential to expand tremendously the reproductive options for women desiring fertility preservation. Indeed, the number of publications regarding the reliability and efficiency of oocyte vitrification has increased exponentially over the past decade. The application of the technique to standard reproductive technologies depends(More)
OBJECTIVE To access the effect of augmenting IVF with assisted hatching in the treatment of poor-prognosis patients. DESIGN Thirty-three poor-prognosis IVF patients were treated with assisted hatching and were compared with 43 control subjects without assisted hatching. SETTING Center for Reproductive Medicine, Swedish Medical Center, Englewood,(More)
OBJECTIVE To describe a method for the training of personnel and the implementation of intracytoplasmic sperm injection (ICSI) into an IVF program. The results of the first 75 cycles are reviewed. DESIGN Retrospective review of the first 75 consecutive ICSI procedures. SETTING Private, community-based IVF program. MAIN OUTCOME MEASURES The(More)
