OBJECTIVE To assess whether total reproductive potential (TRP), the chance of a live birth from each fresh cycle (fresh cycle plus frozen transfers), could be calculated from the national Society for Assisted Reproductive Technology Clinic Outcome Reporting System (SART CORS) database and whether information not available in SART CORS resulted in significant changes to the TRP calculation. DE...
OBJECTIVE To study the effect of freeze-thaw on embryos derived from intracytoplasmic sperm injection (ICSI) using surgically retrieved and ejaculated spermatozoa. DESIGN Retrospective study. SETTING Private IVF center. PATIENT(S) Three hundred eighty-three patients undergoing frozen-thawed ET cycles. INTERVENTION(S) Testicular sperm aspiration (TESA) or percutaneous epididymal sperm as...
OBJECTIVE To compare cryopreservation of mature human oocytes with slow-rate freezing and vitrification and determine which is most efficient at establishing a pregnancy. DESIGN Prospective randomized. SETTING Academically affiliated, private fertility center. PATIENT(S) Consenting patients with concerns about embryo cryopreservation and more than nine mature oocytes at retrieval were ran...
OBJECTIVE To estimate age-specific probabilities of live birth with oocyte cryopreservation in nondonor (ND) egg cycles. DESIGN Individual patient data meta-analysis. SETTING Assisted reproduction centers. PATIENT(S) Infertile patients undergoing ND mature oocyte cryopreservation. INTERVENTION(S) PubMed was searched for clinical studies on oocyte cryopreservation from January 1996 throu...
OBJECTIVE To evaluate long-term outcome of autotransplantation of cryopreserved hemi-ovaries into ewes. DESIGN Animal study. SETTING University fertility center, Hospices Civils de Lyon; and Ecole Nationale Vétérinaire de Lyon. PATIENT(S) Grivette ewes. INTERVENTION(S) Six hemi-ovaries from 6 ewes aged 6 to 12 months were frozen with a slow cooling protocol using 2 M of dimethyl sulfoxi...
A method for the cryopreservation of third-stage infective juveniles (IJ) of Steinernema carpocapsae and Heterorhabiditis bacteriophora was developed. Cryoprotection was achieved by incubating the nematodes in 22% glycerol (S. carpocapsae) or 14% glycerol (H. bacteriophora) for 24 hours, followed by 70% methanol at 0 C for 10 minutes. The viability of S. carpocapsae frozen in liquid nitrogen as...
Quality of glazed (G) and non-glazed air-blast frozen rainbow trout (Oncorhynchus mykiss) was evaluated after applying different modern (M: microwave oven; U: ultrasonic; HVEFT: high voltage electrical field; O: ohmic heating) and conventional (S: steam cooking; W: water; R: refrigeration) thawing methods. Glazed frozen samples thawed by modern and conventional methods showed an increase in pro...
