According to the sources provided, there is limited information specifically addressing the effect of Cosentyx (secukinumab) on fertility in women. Cosentyx is a medication used to treat various inflammatory conditions, including psoriasis and psoriatic arthritis [1].

The first source, Drug Patent Watch, provides information about the drug but does not directly address its impact on fertility in women [1]. The second source, a study published in the journal Dermatology and Therapy, focuses on the safety and efficacy of Cosentyx in treating psoriasis and psoriatic arthritis but does not mention its effect on fertility [2].

However, the third source, Everyday Health, provides general information about psoriatic arthritis and starting a family. It states that women with psoriatic arthritis can conceive and have a healthy pregnancy, but it is important to discuss medication options with a healthcare provider [3]. This implies that the impact of Cosentyx on fertility in women may be a topic for discussion with a healthcare provider.

While the sources do not provide specific information about the effect of Cosentyx on fertility in women, it is important to note that many medications, including biologics like Cosentyx, may have potential effects on fertility. It is recommended that women who are planning to conceive or are already pregnant discuss their medication options with a healthcare provider to ensure the safety and well-being of both the mother and the baby.

In conclusion, based on the provided sources, there is limited information regarding the effect of Cosentyx on fertility in women. It is advisable for women who are planning to conceive or are already pregnant to consult with their healthcare provider to discuss the potential impact of medications, including Cosentyx, on fertility and pregnancy.
