Summary
Male infertility is a significant concern following imperforate anus repair in infancy. Many patients experience ejaculatory or sperm production issues, but some cases can be treated to retrieve sperm.
Area of Science:
- Urology
- Reproductive Medicine
- Pediatric Surgery
Background:
- Congenital genitourinary abnormalities frequently co-occur with imperforate anus.
- Cryptorchidism is a common finding in patients with imperforate anus.
Purpose of the Study:
- To evaluate infertility in men who underwent pull-through procedures for imperforate anus in infancy.
- To identify causes of male infertility in this cohort and assess treatment outcomes.
Main Methods:
- Retrospective evaluation of 20 men treated for imperforate anus.
- Assessment of genitourinary abnormalities, ejaculatory function, sperm parameters, and vasal/epididymal patency.
- Sperm retrieval techniques including reconstruction, sperm reservoir insertion, and microsurgical epididymal sperm aspiration were employed.
Main Results:
- Seven patients had no ejaculate (aspermia), 11 were azoospermic.
- Bilateral vasal obstruction was noted in 5 men, likely related to the initial surgery.
- Sperm retrieval was successful in 9 men, leading to 2 pregnancies.
- Associated conditions included renal abnormalities, recurrent epididymitis, and spina bifida.
Conclusions:
- Male infertility following imperforate anus repair is multifactorial.
- Causes range from ejaculatory dysfunction to obstructive azoospermia and congenital malformations.
- Some infertility causes are treatable, offering potential for sperm retrieval and assisted reproduction.
