The effects of follicle diameter on the in vitro fertilization capacity of bovine oocytes aspirated from the slaugthered ovaries
Abstract
The aim of this study was to determine the maturation and fertilization capacities of bovine oocytes aspirated from slaugthered ovaries in relation with the follicle diameter. A number of 115 ovaries collected from the slaugthered cows at a local slaughterhouse were used as the materiaL. Peripheral follicles were counted according to the their diameters (2-6 mm-group i and 6-10 mm-group II). All follicles were punctured with an 18 G needIe hold on a 5 ml syringe and aspirated cumulus-oocyte complexes were classified in regard to their morphological apperance. Only Grade I, II and III oocytes were then placed in maturation medium (TCM-199+%20 (v/v) ECS+BSA) and incubated under an atmosphere of 5% C02 at 39°C for 22-24 hr. After IVM, maturated oocytes were fertilized by adding 1-2 LLL (i X 106 ), swim-up separated sperm to the fertilization media (Tyrode's albumin lactate pyruvate medium-TALP) for in vitro fertilization under an atmosphere of 5% C02 at 39°C for 18-19 hr. Heparine (LO Ilg/ml) was used as the capacitating agent. The datas obtained at the all stages were recorded and statistical evaIuation was done with the Student's T test. A total of 549 (4.77:t2.09) oocytes were aspirated from 588 (5.11:t2.39) follicles with an aspiration rate of 93.3% in group i and 275 (2.5:t1.87) COC were aspirated from 300 (2.72:t1.58) follicles with an aspiration rate of 91.7% in group II. After the maturation period 401 of 549 oocytes in group I and 217 of 275 oocytes in group II were found as mature with amaturation rate of 73% and 78.9%, respectively (p>0.05). In 165 of 401 in group I (41.1 %) and 107 of 217 incubated oocytes in group II (49.3%), both male and female pronuclei were detected. As a conclusion, it was evident that the ovaries collected from the slaugtherhouse are suffİcient potentials for in vitro embryo production, although a great variation between the maturation and fertilization capacities of oocytes aspirated from the peripheral follicles could be observed. It was also obvious that there is a significiant relation between the follicle diameter and maturation and fertilization capacities of oocytes since the fertilization rates increases as the follicle diameter rises
