Assessing the Fertility Status of Men With Spinal Muscular Atrophy (SMA)

The Assessment of Fertility in Men With Spinal Muscular Atrophy (SMA)

This study will aim to assess the fertility status of men with Spinal Muscular Atrophy (SMA) not on disease-modifying therapies.

Participants will:

1. Complete online questionnaires that will assess SMA diagnosis and disease burden, medical and surgical history, medication usage, and fertility status and perspectives.
2. Over the 3-month initial study baseline period participants will provide two separate ejaculates for semen analysis and a single determination of sperm quality using DNA fragmentation testing using home collection and subsequent shipment to a central laboratory.
3. Over the initial study baseline period of 3 months study participants will obtain a blood test to determine male reproductive hormone levels.

During the 24-month study duration, participants will be requested to undergo a yearly semen analysis and complete online relevant questionnaires.
