Couples trying to conceive might wish to try to improve their fitness and wellbeing before applying for reproductive help through international medical insurance policies.
Founder of www.tamzinfreeman.co,uk Tamzin Freeman explained a woman is more likely to become pregnant if "both partners are in optimum health".
People ought to quit smoking, which can cause early menopause and infertility, as well as increase the likelihood of an infant being born with birth defects or the woman suffering from a miscarriage.
Furthermore, both man and woman should exercise for a minimum of 20 minutes every day, Ms Freeman added, recommending people walk through nature.
Alcohol and caffeine should not be consumed "unless completely unavoidable", the expert declared, arguing if someone is at a big celebration where everyone is drinking champagne and they are socially obliged to join in, they should still only drink one glass.
However, at least two litres of water every day ought to be drunk, she argued.
A recent editorial in the Australian and New Zealand Journal of Public Health authored by La Trobe University researcher Spero Tsindos described the argument that this much water ought to be drunk every day as a "myth".
It pointed out the fluids in vegetables, fruits and other drinks count towards this target, while the commonly-held belief that caffeinated beverages such as tea and coffee cause dehydration is also incorrect.
Ms Freeman also stated people trying to conceive should have at least eight hours of sleep every night and should aim to go to bed "at a regular time".
Couples should also try to reduce the amount of stress they feel, she added, noting: "Of course a big stress is the issue of conceiving itself, but try to enjoy it."
It can take four months for an unhealthy person to lose all of the "ill effects of 'bad' living", she claimed, suggesting that couples alter their lifestyles several months before they plan to conceive.
This can ensure "the healthiest pregnancy and the most trouble-free conception", the expert remarked.
