TO ASSESS THE EFFECT OF SEMEN ON THE FERTILIZATION RATE OF IN VITRO FERTILIZATION
Main Article Content
Abstract
Objectives: To assess the effect of semen on the fertilization rate of in vitro fertilization. Subjects and methods: Retrospective study of 660 in vitro fertilization couples from 11/2020 to 12/2021. Comparison of the fertilization rate of mature oocyte (MII) between ejaculated and epididymal or testicular sperm; between fresh and frozen sperm; among the groups of asthenozoospermia, oligozoospermia and teratozoospermia. Results: fertilization rates in the group of ejaculated and epididymal or testicular sperm were 0.78 ± 0.20% and 0.75 ± 0.24% (p> 0.05); in the group of fresh and frozen sperm were 0.77 ± 0.20% and 0.81 ± 0.16% (p> 0.05). Fertilization rates of the asthenozoospermia, oligozoospermia and teratozoospermia were 0.80 ± 0.20%, 0.68 ± 0.27%, and 0,81 ± 0.18%, respectively. (p2-3) < 0,05). Conclusion: sperm freezing and methods of semen collection did not affect on the fertilization rate of IVF. Oligozoospermia significantly reduced the fertilization rate of mature oocytes compared to teratozoospermia.
