5-alpha-reductase inhibitor (type II)
Finasteride when planning pregnancy
For couples trying to conceive, every chronic medication deserves a careful pre-pregnancy review. Finasteride (Finasteride) at 1mg may need to be continued, switched, or stopped before conception, depending on the active ingredient Finasteride and the indication. The right answer is rarely the same for everyone and rarely "just stop the medication."
Pre-conception review of Finasteride
According to the prescribing information for Finasteride, the pre-conception decision balances the risk of the medication during pregnancy against the consequences of leaving the underlying condition untreated. Some 5-alpha-reductase inhibitor (type II) medications are continued safely through pregnancy; others are switched to safer alternatives before conception or in early pregnancy. Finasteride binds with high affinity to 5-alpha-reductase type II, blocking the conversion of testosterone into DHT.
Effect on fertility itself
Some medications affect fertility directly — by altering ovulation, sperm parameters, hormonal balance or libido. Whether Finasteride has any documented effect on fertility depends on Finasteride; the prescribing information notes any data. Anyone trying to conceive should discuss Finasteride with the prescriber and a fertility specialist if conception is taking longer than expected.
