The use of Intracytoplasmic sperm injection (ICSI) has increased in the last decades regardless of the cause of infertility. Despite the increased use there is no clear evidence that ICIS is more effective than conventional in vitro fertilization (IVF) for non-male factor infertility. The investigators therefore aim to perform a prospective randomized controlled study to compare between ICSI and conventional IVF in women between 39 to 44 years of age with non-male factor infertility.
