In men with myotonic dystrophy type 1 (MD1), reproductive problems due to a high prevalence of testicular atrophy and oligospermia or azoospermia are well-known manifestations of the disease.[1] In MD1 women, fertility impairment is also considered highly probable.[2] To the best knowledge of the authors, only limited and inconsistent data exist concerning the fertility of women patients with other muscular dystrophies, ie, myotonic dystrophy type 2 (MD2) or FSHD, or carriers of Duchenne muscular dystrophy mutations (cDMD). This evidence concerns the gene LY86 and muscular dystrophy.
