Doctors familiar with the study said that many women may be unaware of the crash in fertility that occurs beyond the age of 35, while some could be fooled into unrealistic expectations by media stories of celebrities starting families in their 40s.Doctors familiar with the study said that many women may be unaware of the crash in fertility that occurs beyond the age of 35, while some could be fooled into unrealistic expectations by media stories of celebrities starting families in their 40s.

Stuart Lavery, a consultant gynaecologist a Hammersmith hospital said that many women were likely to be shocked at the sharp decline in fertility among women in their early 40s.
