Experiments were undertaken to develop ICSI to produce caprine embryos outside the normal breeding season. Oocytes with 2-4 layers of cumulus cells from 2-6 mm follicles were washed twice with Tyrodes + 0.4 mg PV A and 0.4 mg sodium pyruvate per ml and incubated in 1 ml of Hepes-TCM 199 + 10 J.Lg each oFSH and bLH (NHPP, NIDDK, NICHD, USDA) + 20% FBS (MM) in a thermos (38.5°C) for 4.5 h. Then, oocytes were transferred into 75 ul of freshly prepared MM under paraffin oil and 5% O2, 5% CO2, and 90% N2. Approximately 26 h after recovery oocytes were denuded with hyaluronidase (100 lU/mi) and pipetting and held at 38.5°C for 90 min. Sperm frozen in egg yolk extender were thawed in a 37°C water bath for 15 sec, and motile fractions were selected by swim-up, then incubated 90 min in TALP with 10 J.tg heparin/ml. Each oocyte was positioned with its first polar body at 6 or 12 0' clock by a holding pipette. Sperm medium (1 J.LI) was added to 10 J.tl medium containing 10% PVP. A sperm cell was aspirated into a pipette, and then injected head first into the cytoplasm of an oocyte in H- TCM 199 + 20% FBS (HM) at 37°C. Injected oocytes were transferred to HM and after 90 min, cultured in 50 J.tl of c- SOF+NEA (Biol. Reprod.52: 141 0-1417). Data analysis was by ANOV A and Bonferroni t-test. Tabulated results show that caprine blastocysts ca~ be derived out of season after use of frozen- thawed sem en and injection of sperm cells with broken tails into ooplasm. Controls included comparable numbers of oocytes activated with Ca ionophopre (5 mM for 1 min), injected without sperm, and injected without sperm and activated by Ca ionophore, none of which cleaved.
