ABSTRACT
OBJECTIVE: To determine the effect of hydrosalpinx fluid-containing medium on murine embryo development and implantation. DESIGN: The development of one-, two-, and four-cell mouse embryos in medium containing 5%, 10%, and 20% of human hydrosalpinx fluid was observed. Implantation rates of mouse embryos transferred into the uterine horn with hydrosalpinx fluid-containing media were determined. SETTING: Private hospital-based fertility center and IVF program. MAIN OUTCOME MEASURE(S): Percentage of embryos continuing cell division and implantation rates after ET. RESULT(S): Hydrosalpinx fluid in culture medium affected embryo development in a dose-dependent fashion. The injection of hydrosalpinx fluid-containing medium into the uterine horn did not affect embryo implantation. CONCLUSION(S): Hydrosalpinx fluid negatively affects murine embryo development, but its presence in the uterine horn at ET did not affect implantation.

PURPOSE: Our objective was to determine the effect of experience on the results with intracytoplasmic sperm injection. METHODS: The quarterly outcome with both ICSI and traditional in vitro fertilization (IVF) in 1994 was analyzed in 475 patients under age 40 undergoing 595 oocyte retrievals. The data represent 307 patients undergoing 379 retrievals for IVF and 165 patients undergoing 216 retrievals for ICSI. RESULTS: Fertilization rates with ICSI improved significantly each quarter (52.96, 62.17, 70.17, and 74.87% in Q-I, Q-II, Q-III, and Q-IV, respectively), while the rate with IVF improved significantly between Q-I (69.9%) and Q-II (80.10%) and slightly but significantly between Q-II and Q-IV (82.88%). The implantation rate per embryo after ICSI improved significantly after Q-I (6.17%) compared to Q-II (10.70%) and Q-IV (12.14%). The pregnancy rate per transfer with ICSI increased steadily after Q-I (13.79, 21.88, 23.53, and 25.00% in Q-I through Q-IV), reaching statistical significance between Q-I and Q-III and between Q-I and Q-IV. CONCLUSIONS: Although acceptable results can be obtained with ICSI after a relatively short period of time, optimum results require substantial experience.
