Abstract

This study reports the follicular growth and oocyte competence for in vitro maturation and fertilization under the influence of circulating eCG. Three to 7 successive ultrasound-guided follicular punctures were performed on 4 pregnant mares from Day 23 until Day 75 of pregnancy and on 5 control mares whose embryonic vesicle was crushed on Day 22. All follicles larger than 5 mm were punctured 24 h after the largest follicle reached 18 mm. Expanded cumulus oocyte complexes (COCs) were stained at recovery to analyze the nuclear stage. Compact COCs were cultured in vitro for 46 h and either stained or processed for in vitro fertilization (IVF) and stained 26 h after IVF. In the control group, no mares showed an increase in eCG levels, whereas all the pregnant mares had concentrations higher than 100 ng/ml from Day 37. The number of follicles flushed during each puncture attempt significantly decreased with time for 3 of 4 pregnant mares. No significant change in this number was observed for the 5 control mares. The maturation rate of the oocytes from follicles 10-14 mm was significantly higher in the pregnant vs. the control group (14 of 17, 82%, vs. 13 of 30, 43%). The difference was not significant for the oocytes from follicles smaller than 9 mm or larger than 15 mm. After IVF, no oocyte was fertilized. The results led us to conclude that eCG is associated with an inhibition of follicular growth and an improvement in oocyte competence for in vitro maturation.

Abstract

Equine oocyte competence after in vitro maturation (IVM) was investigated in terms of the diameter of the follicle of origin and the stage of the estrous cycle, with three criteria of maturation: nuclear stage after DNA Hoechst staining, meiotic spindle morphology after tubulin immunocytochemical staining, and cortical granule localization after lectin labeling. Seven successive in vivo ultrasound-guided follicular punctures were performed on 10 cyclic saddle mares, alternatively at the end of the follicular phase (after induction of ovulation with a gonadotropin injection) and in midluteal phase (with or without a gonadotropin injection). Expanded cumulus-oocyte complexes (COCs) were stained at collection, and compact COCs were stained after in vitro culture. They were observed under a confocal microscope. Successive punctures on one mare provided 0.9 preovulatory COCs and 8 immature COCs per 22 days. Among the preovulatory oocytes, 55% had completed nuclear and cytoplasmic maturation, 86% of which displayed a normal meiotic spindle. Of the 262 oocytes cultured in vitro, 37% completed nuclear maturation. The nuclear and cytoplasmic maturation rate significantly increased with follicle diameter. The IVM rate tended to be higher in follicular phase and tended to increase in luteal phase with the gonadotropin injection. The meiotic spindle morphology was not significantly different between the classes of follicular diameters. This study provided the opportunity to increase the number of characterized oocytes collected per cycle and per mare. This is the first report showing the progressive acquisition of meiotic competence in the equine oocyte during antral follicle growth and is the only description of the equine meiotic spindle.
