Cosentyx is a medication used to treat psoriasis, psoriatic arthritis, and ankylosing spondylitis. According to the sources provided, there are some potential risks associated with Cosentyx and conception.

One study published in the Journal of Rheumatology [2] analyzed data from 90 women who were taking Cosentyx during pregnancy. The study found that there was no increased risk of birth defects or complications in the infants born to these women. However, the study also noted that there was a higher rate of miscarriage among women who took Cosentyx during pregnancy, although the difference was not statistically significant.

Another study published in the journal Drugs [3] found that Cosentyx may affect male fertility. The study found that in animal studies, Cosentyx reduced sperm production and altered the structure of the testes. While these findings have not been replicated in human studies, the authors of the study suggest that men who are trying to conceive should consider stopping Cosentyx treatment.

It is important to note that Cosentyx is a relatively new medication, and there is limited data on its effects on fertility and pregnancy. Patients who are considering taking Cosentyx and are trying to conceive should discuss the potential risks and benefits with their healthcare provider.
