New research conducted on men with non-obstructive azoospermia (NOA), lack of sperm in the semen stated that the condition is not due to an obstruction within the reproductive system and it is a wrong consideration that the people are not suitable to undergo IVF procedure.
New research showed that sperm produced from men with non-obstructive azoospermia and obstructive azoospermia are equally capable of producing embryos.
Study revealed that the elevated implantation rate per embryo transferred and to the resultant live births indicates to the quality of embryo being created with either type of surgically regained sperm.
While assessing the possibility of NOA sperm, also researchers were able to study paternal effect on genomic activation. One of the initial morphologic signs of embryonic genome activation is improved cell-to-cell observance at the 8-cell stage, leading to compaction.
Research found that embryonic compaction was similar in all three groups. These outcomes revealed that zygotic activation is independent of sperm origin and type of azoospermia.
