For women under the age of 35, infertility is defined as the inability to conceive after one year of unprotected intercourse (for those women over 35 years of age it is six months). For those who have a known diagnosis such as endometriosis, polycystic ovarian syndrome, male factor infertility, irregular cycles and known fallopian tube scarring or blockage, typically do not need to wait the traditional above period of time. Infertility affects about one in seven couples of childbearing age. Current statistics show that about 35% will be female related, 35% will be male related, 20% will be a combined problem and the remaining 10% will be unexplained. Consequently, it is crucial to treat both the woman and man when assessing the infertility work-up phase of treatment.
