One major review of medical studies revealed that while 90 per cent of healthy, fertile couples conceive in the first year of regular unprotected sex, and another five per cent get pregnant in the second year, in the first three years of unexplained infertility, one in three couples will have a successful pregnancy with no treatment at all.
Dr Murage advises a young couple to wait longer and a good number will still conceive naturally.
Second, he also recommends ovulation medications combined either with timed intercourse or intra-uterine insemination of sperms.
"Some couples will not conceive with simple measures and may end up requiring more complex treatments like intra vitro fertility," Dr Murage explains.
The doctor says most young couples will conceive with simpler interventions, whereas some will need more complex interventions.
"Unfortunately, a small percentage of couples will not achieve success despite repeated treatments," he says.
Other prescriptions for women facing unexplained infertility that have not been scientifically proven to do anything but "enrich their prescribers", say experts, are immunoglobins, baby aspirin, antioxidant vitamins, and heparin.
For men, a good option is trial courses of antibiotics when no evidence of sexually transmitted disease or infection has been found.
