An interview with Sue Hall Esleck. Interview by Connie R. Curran

The present report covers the results of a 38-month period in which 2853 consecutive intracytoplasmic sperm injection (ICSI) cycles were performed in 1953 couples. These couples were afflicted with male factor infertility and had at least one previous failed conventional in vitro fertilization (IVF) treatment cycle. In other couples, the husband had semen parameters incompatible with conventional IVF or suffered from excretory or secretory azoospermia where it was possible to recover spermatozoa by microsurgical epididymal sperm aspiration (mesa) or by testicular sperm extraction (tese) procedure. Overall, the 2-PN fertilization rate was 62% per retrieved metaphase II oocyte and 70% per successfully injected metaphase II oocyte. Embryo transfer was performed in 91% of started cycles. The cumulative pregnancy rate (positive HCG) was 34% per started ICSI treatment and 37% per embryo transfer.
