Fibroids and Pregnancy

Fibroids are the commonest type of benign tumors to grow in the womb. They are extremely common and the prevalence is estimated to range between 20 and 50% of all adult women. They are commonest among women of black African ancestry but they are seen in women of all races. The prevalence increases with increasing age and therefore they are rarely seen in women in their teens or early 20s. They are commonest in women in their 30s and 40s. They will tend to gradually shrink after the woman has gone through menopause, which usually occurs in the late 40s and early 50s.

Fertility and body weight are factors in the presence of fibroids as they tend to be commoner among women who remain childless and those who are overweight or obese. The two are independent factors.

Fibroids come in different sizes. They can be smaller than a pea and on the other end of the spectrum bigger than a melon.

Effect  of fibroids on Fertility:

Fibroids can be a factor in fertility difficulties for an individual even though they are a minor factor in the overall infertility and sub-fertility sphere, being significant in less than 3% of all cases.

What this means is that, even though very common, fibroids are normally inconsequential when it comes to conceiving and successfully carrying a pregnancy.
