Erectile dysfunction is a condition that may affect a man's sex life and can cause stress, which results in relationship problems.

But, sometimes, the drugs used for their treatments can also be culprits, as Gabapentin does.

Research on the sexual side effects of Gabapentin is still incomplete, but the research that has been made shows that this drug may produce different symptoms in both genders. It can cause anorgasmia and decreased libido in women, even at low doses.

According to research, anorgasmia is found in women who take 900mg of Gabapentin regularly. Women taking both 900 and 1800 mg of Gabapentin got gabapentin-induced anorgasmia and reduced libido.
