Surveys of young men and women tell us that most would choose to have two or three children, but the sad reality is they will more likely have one or none.

In summary

Men’s Fertility

  • male fertility declines from 35
  • genetic material in sperm deteriorates with poor lifestyle
  • associated with higher risk of miscarriage and birth abnormalities

Women’s Fertility

  • women are born with all the eggs they will ever have :1-3 million eggs
  • only 3-400 eggs will ovulate, the remainder simply degenerate
  • rate of degeneration varies between individuals. So biological age does not always equate with chronological age
  • chance of pregnancy in any month is best before 25 and fertility starts to decline after 30
  • at 35 the chance of conceiving is half that at 30 and at 40 is half that at 35
  • numbers and quality of eggs drop at least 10 years before fertility is lost

Lifestyle factors affect conception:

  • age: IVF can’t fix old eggs
  • weight and medical history
  • drugs, smoking and alcohol
  • sexually transmitted diseases such as Chlamydia contracted years before

I can’t afford children now...

Yes, children do cost but the expense is spread over many years

How do I decide? The choice is yours...

  • Have a family early in life
  • Pursue a career and then have children
  • Decide to combine your career and a family
  • Or don’t have children at all

Just remember, no matter what choices you make, be sure that you are relying on the best information available 

Then when you make your decision it will be the right one for you and you need not feel guilty about those choices no matter what people say, and it is ok to change your mind

Can you afford to wait? Won't IVF fix any problems?

  • The chances of conceiving in a IVF cycle for a healthy young woman is highest when she is aged 37 or less
  • For older men and women the success rate drops with age
  • Other factors such as the nature of the infertility problem, the type of treatment and lifestyle determine outcome
  • But in general, the older you are the lower the success rate
  • IVF will not overcome lifestyle factors in men and women including drugs, alcohol, smoking, STDs and weight problems.
  • IVF is emotionally traumatic
