Women in their late 30s and 40s should still think about sexual health and contraception, according to the Family Planning Association (FPA).
While acknowledging that female fertility levels start to decline after the age of around 35, the organisation has warned against complacency with regard to family planning.
According to FPA spokesperson Rebecca Findlay, women should make use of contraception right until the menopause and the government and healthcare providers need to start targeting this demographic more.
"When you look at the abortion for women aged 40-44 and under the age of 16, they are actually identical," she explained.
"When you think how much time we spend, quite rightly, talking about unplanned teenage pregnancies, it seems like the over 35s have become quite a forgotten age group."
These comments come soon after the publication of a joint report by Relate, One Plus One and the Tavistock Centre for Couple Relationships, calling for more support for new parents.
According to the report, 65 per cent of couples feel that their relationship gets worse after the arrival of a child.
