Abstract:
Objective To observe the influence of the sperm abnormalities on conventional invitro fertilization therapy outcome. Methods Sperm of 105 infertile husband's semen was analyzed. The patients were divided into three groups according to the sperm morphology observed Using Kruger 's criteria: normal sperm morphology group (sperm normal morphology ≥ 15 % ), mild sperm abnormalities group( sperm normal morphology 10%- 15%), middle sperm abnormalities group (sperm normal morphology 5 % - 10 % ). Fertilization rate, cleavage rate, good quality embryo rate, implantation rate, clinical pregnancy rate and abortion rates were compared to study the influence of the sperm abnormalities on conventional IVF outcome. Results ①Fertilization rate(79.4 % vs 78.3 % ), cleavage rate(104. 6% vs98. 6%), good quality embryo rate(58. 1% vs 53. 9%), implantation rate (31.7% vs 30. 8%), clinical pregnancy rate(48.1% vs 42. 3%)and abortion rates(13.0% vs 18. 2%)were not significantly different between normal sperm morphology group and mild sperm abnormalities group(P>0. 05). ②The fertilization rate (79.4% vs 63.9%), good quality embryo rate(58. 14% vs 48.23%), implantation rate (31.7% vs 16. 7%) and clinical pregnancy rate(48.1%vs24.0%) of the normal sperm morphology group were higher than middle sperm abnormalities group(P<0.05). The abortion rates(13.04% vs 28. 57%) and cleavage rates(104.6% vs 102.9%) were not significantly different(P>0. 05). ③The fertilization rate (78.3% vs 63.9%), good quality embryo rate (53. 9%vs 48. 2%) of the mild sperm morphology group were higher than middle sperm abnormalities group(P <0.05). Implantation rate (30.8% vs 16. 7%) , clinical pregnancy rate(42.3% vs 24.0%) , abortion rates(13. 0% vs 28. 6%) and cleavage rates(104.6% vs 102.9%) were not significantly different (P>0. 05). Conclusions There is a significant influence of middle sperm abnormalities on IVF fertilization rate, good quality embryo rate, implantation rate and clinical pregnancy rate. However, it could not be influenced on mild sperm abnormalities.
