Broekmans FJ, Kwee J, Hendriks DJ, Mol BW, Lambalk CB. The idea is that for women beyond age 35, every month counts and if made to wait another six months to prove the necessity of medical intervention, the problem could become worse.

By the end of this step, most of healthcare professionals will be able to sketch out their provisional diagnosis. Klinefelter�s Syndrome: Is a genetic condition in which each cell in the human body has an additional X chromosome--men with Klinefelter�s Syndrome have one Y and two X chromosomes.  Physical symptoms include peanut-sized testicles and enlarged breasts.  A chromosome analysis is used to confirm this analysis.  If this condition is treated in its early stages (with the drug hCG), sperm production may commence and/or improve.  However, Klinefelter�s Syndrome eventually causes all active testicular structures to atrophy.  Once testicular failure has occurred, improving fertility is impossible. The corollary to this is that, by definition, failure to conceive in women under 35 isn't regarded with the same urgency as it is in those over 35.
