For couples who fail to conceive naturally, there are artificial methods such as in-vitro fertilisation (IVF) and intrauterine insemination (IUI). However IVF treatment is emotionally and physically draining, and should only be considered as a last resort.

It is also very costly. One IVF cycle costs between $7,000 and $14,000, and some couples will need more than one try, while others may not succeed at all.

So even with IVF and IUO, it is still not a good idea to wait. At the KK Women’s and Children’s Hospital IVF Centre, nearly 33% of women below 40 achieved pregnancy but this fell to 12% for those over 40. Women less than 40 also reported a lower miscarriage and cancellation rate.

Clearly, the chances of pregnancy decrease with increasing age. When it comes to baby-making, it is not a matter of “hitting the jackpot” on the very first try. Hence couples should give ample time and allow for unexpected delays. Watch that clock!
