Fertility is a very personal aspect of our bodily health, and it differentiates person to person.
If you're worried about your fertility, you're definitely not alone. A Body Logic study found that 63% of women worry about their fertility.
Among millennials, 72% expressed a desire to have kids in the future.
Women in the study were found to be substantially more likely to worry about being able to conceive than men.
More than 6 in 10 women were worried they might not be able to have kids; however, just 1 in 10 women between the ages of 15 and 44 actually have difficulty getting or staying pregnant.
'There's no 'right time' to have a baby,' Karen Morton, gynaecologist and obstetrician at Dr Morton's, told NetDoctor.
'This is a simple truth. In my antenatal clinic I see women of 25 having their fourth child and women of 40 having their first.'
Social and economic trends have also contributed to a delay in women having their first child.
According to the Infertility Fears study, these trends have caused a steady rise in the average age of motherhood.
'2016 marked the first year on record in which women in their 30s had more babies than women in their 20s.'
Among all women surveyed, the most common cause for concern was not getting a regular period.
For men, only a third reported worrying about being unable to conceive.
For male respondents, the most common worry was that they might not produce enough sperm to impregnate their partners.
The average father of a newborn is now 31 years old.
