- Brief Summary
The objective of this study was to evaluate the advanced maternal age as a rationale for performing intracytoplasmic morphologically selected sperm injection (IMSI).
This prospective randomized study included couples undergoing intracytoplasmic sperm injection (ICSI) as a result of advanced maternal age (≥ 37 years old). Couples were randomly allocated to receive one of two sperm selection procedures (ICSI, n = 33; or IMSI, n = 33). The groups were compared with regard to fertilization rate, percentage of high-quality embryos, implantation, pregnancy and miscarriage rates.

Group Intervention Description ICSI group Intracytoplasmic sperm injection (ICSI) This group was provided with conventional intracytoplasmic sperm injection (ICSI). This treatment is routinely used to treat infertility. Sperm selection in the ICSI group is analysed under a magnification of 400x using an inverted microscope. Intracytoplasmic morphologically selected sperm injection Intracytoplasmic morphologically selected sperm injection Intracytoplasmic morphologically selected sperm injection (IMSI) is an established modified ICSI procedure. Sperm selection in the IMSI group is examined at high magnification using an inverted microscope equipped with high-power differential interference contrast optics (DIC/Nomarski). The total calculated magnification is x6.600. The sperm cells exhibiting normally shaped nuclei and normal nuclear chromatin content are selected for injection.
