And as aging occurs, egg quality, or the likelihood of an egg being genetically normal, decreases as well. Surgery for epididymal blockage: A blocked epididymis can be surgically repaired. It is increasingly recognized that egg quality is of critical importance and women of advanced maternal age have eggs of reduced capacity for normal and successful fertilization. Known uterine fibroids or endometrial polyps: Uterine abnormalities, such as fibroids that indent the endometrial cavity and endometrial polyps, can impair how the endometrium (the lining of the uterus) and embryo interact to lower implantation and pregnancy rates. Their cumulative probabilities of conception are 60% within the first 6 months, 84% within the first year, and 92% within the second year of regular fertility-focused sexual activity.

For example; a woman who has no history suggestive of previous pelvic inflammatory disease or endometriosis, there is no justification to request a laparoscopy especially after normal hysterosalpingography study [33]. These include advancing maternal age, severe male factor infertility (whereby ICSI can be used to fertilize the egg), and endometriosis, amongst many others. The sperm must provide the zygote with DNA, centrioles, and activation factor for the embryo to develop. The impact of fibroids located elsewhere in the uterus are controversial and do not always require surgery. A doctor may diagnose infertility if a woman has not become pregnant after 1 year of trying. Are Sequence Family Variants Useful for Identifying Deletions in the Human Y Chromosome?
