Fertility drugs given 'all-clear' in new study

Concerns about the use of letrozole, an easy-to-use and inexpensive drug for the treatment of infertility, appear to be unfounded, according to a major study co–authored by Dr. Togas Tulandi, Director of Division of Reproductive Endocrinology and Infertility, McGill University Health Centre (MUHC) and Chief of Obstetrics and Gynecology at the Jewish General Hospital, and Professor of Obstetrics and Gynecology at McGill University. Their findings, which are currently available in an early online edition of Fertility and Sterility, showed that babies whose mothers were treated with letrozole had the same rate of birth defects as those whose mothers were treated with clomiphene citrate ?the low-risk, first-line treatment for infertility for more than 40 years.

"We found no statistically significant difference in the overall rates of major and minor malformations or chromosomal abnormalities between newborns in the two groups," says Dr. Tulandi. "Our findings indicate concerns about a link between letrozole and birth defects are unfounded. This is significant because it confirms that letrozole can indeed be used in the treatment of infertility without increasing risk to the fetus."

The study contradicts an earlier, much smaller study linking letrozole to increased rates of inherited malformations. This study led to widespread concern about the use of letrozole, a drug which has been widely used in the treatment of infertility in recent years.

"There were several methodological problems with the earlier study," says Dr. Tulandi. "For one thing, it compared the incidence of birth defects in children conceived spontaneously with that in children conceived through fertility treatments using letrozole. This is an apples-and-oranges comparison, because there are always fewer birth defects in children conceived spontaneously." The earlier study also compared different age groups between the control and treatment.
