The chances of spontaneous conception decline with age (Photo: Courtesy)

Dear Doctor,

I am in my mid-forties and been trying to conceive for more than a year. Is there any way I can be helped?


Dr Alfred Murage says,

Dear Meredith,

The chances of spontaneous conception decline with age, more so from mid-thirties onwards. It is estimated that women older than 40 only have a 5 per cent chance of conception with every cycle.

This is in great contrast to women in their late 20s and early 30s, whose chances of conception are 4 to 5 times higher. By the time you hit 45, chances of conception with your own eggs are almost nil.

It doesn’t end there -- you also have higher chances of suffering a miscarriage. And pregnancy-related complications also occur more commonly.

But despite the statistics, your motivation to conceive shouldn’t be dampened by anyone. It may be that this is the right time for you to start a family.

You may already have settled down with many of your life goals, including education and career. Your current financial stability may be in favour of caring adequately for a family. You are also likely to be able to completely focus on the tasks of bringing up your child.

You must, however, accept the reality that you may take longer to conceive, or even end up not conceiving at all. You must immediately consult a fertility specialist and get a full reproductive evaluation done.

Your male partner should come along and also get evaluated. The most critical factor will be your prevailing ovarian function. It’s likely your egg numbers will be significantly declined, and their quality too will be poorer. This is a biological phenomenon that occurs with advancing age and cannot be reversed.

Your fertility specialist will advise on best options to try and help you conceive. Simple, or even more advanced fertility treatments may be offered. However, not even the most advanced fertility treatments, like in-vitro fertilization (IVF), can compensate for low egg numbers and quality.

Your success rates will be dismal, and you might end up doing several cycles of treatment to conceive. Unfortunately, most women in their 40s -- using their own eggs -- will never get pregnant even after several cycles of fertility treatments.

There’s always the option of using donated eggs. This requires some contemplation, and is obviously not an easy choice for everyone. The odds of getting pregnant with donated eggs are much higher, but must also involve doing IVF.

If the thought had crept up to you when you were much younger, you could have frozen your eggs for future use. Those in younger age groups, with foreseeable potential of delaying child-bearing till the later years, could consider this option.

It remains possible that you may still conceive. Maintain a healthy lifestyle and be open to realistic advice from your fertility specialist.
