London, Feb 6 (ANI): Use of fertility drugs does not raise a woman’’s risk of developing ovarian cancer, according to a new study.

The study has been published online in the British Medical journal.

For the past 30 years, debate has been going on as to whether use of fertility drugs increases a woman’’s risk of developing ovarian cancer.

Previous studies have given conflicting results and concerns remain.

Therefore, Allan Jensen and colleagues at the Danish Cancer Society examined the effects of fertility drugs on ovarian cancer risk by using data from the largest cohort of infertile women to date.

The study included 54,362 women with infertility problems referred to all Danish fertility clinics between 1963 and 1998. 156 of these women had ovarian cancer. After adjusting for several risk factors, the researchers assessed the effects of four groups of fertility drugs over an average period of 16 years.

They found no overall increased risk for ovarian cancer after use of any fertility drug. They also found no increased risk among women who had undergone 10 or more cycles of treatment or among those who did not become pregnant.

Although the authors did observe a statistically significant increase in risk of the most common serious type of ovarian cancer among women who had used the drug clomiphene, they stress that this was probably a chance association. (ANI)
