Relationship of follicular size to the development of intracytoplasmic sperm injection-derived human embryos.

Objective: To compare the embryonic development of oocytes obtained from follicles of different sizes.

Materials And Methods: Oocytes (n = 819) were retrieved from women at 40 years of age or younger during 86 in vitro fertilization cycles and categorized as small, medium, or large based on the estimated volume of follicular fluid at the time of retrieval.

Results: The rates of good quality embryos from the large, medium, and small groups on days 2 and 3 were 76.

Comparison of day 2 tubal embryo transfer with day 3 embryo transfer into the uterus of intracytoplasmic sperm injection derived human embryos.

Objective: To compare the results of embryo transfer into the uterus (ET) performed on day 3 vs. tubal embryo transfer (TET) on day 2 in couples diagnosed with male factor infertility.

Materials And Methods: We collected data from 34 and 110 patients who underwent intracytoplasmic sperm injection (ICSI) followed by either TET on day 2 or ET on day 3 (January 2001-June 2005), respectively.
