Cohort study of perinatal outcomes of children born following surgical sperm recovery.
There is a relative paucity of data on perinatal outcomes following Intracytoplasmic Sperm Injection using surgically retrieved sperm. In this retrospective cohort study, data were collected on couples who conceived following Intracytoplasmic Sperm Injection using surgically retrieved sperm from 1996 to 2014. Outcome measures included live birth, miscarriage, congenital abnormality, birthweight, gestation at delivery, stillbirth and neonatal death. Outcome measures were compared according to male diagnosis and sperm source. Live birth rates were similar between groups (obstructive azoospermia 90%, non-obstructive azoospermia 83%, p = 0.55). There was a trend towards higher miscarriage rates in the non-obstructive azoospermia group (17% versus 9%, p = 0.45). Other perinatal outcomes were similar between groups. In those with obstructive azoospermia, live birth rates were similar regardless of source of sperm (epididymal 89%, testicular 91%, p = 0.79). Median gestation at delivery was earlier in the epididymal sperm group (39 weeks versus 40 weeks, p = 0.02). Other perinatal outcomes were unaffected by sperm source. Overall these results are reassuring, suggesting high live birth rates regardless of diagnosis or sperm source, although there may be higher miscarriage rates in cases of non-obstructive azoospermia. Other perinatal outcomes were not affected by diagnosis or sperm source.
