Joe and Jane desperately want to have children, and although they have tried for two
years, they have not been successful. Finally, they both agree to consult a specialist,
and it turns out that Joe suffers from oligospermia (a low sperm count). He doesn't

should the specialist tell him? (1 mark). What possible option(s) may the specialist
advise the couple? Why? (2 marks).
