• Infertility is the inability to conceive after at least one year of unprotected intercourse. However, depending upon the age of the couple, an infertility evaluation may be recommended even earlier.
• Male infertility is involved in approximately 40% of the 2.6 million infertile married couples in the U. S. One-half of these men experience irreversible infertility and cannot father children.
• Hormone disorders, illness, reproductive anatomy trauma and obstruction, and sexual dysfunction can temporarily or permanently affect sperm and prevent conception.
• Many infertility cases are caused by a treatable medical condition, but some disorders become more difficult to treat the longer they persist without treatment.
