Infertility can result from problems in males and females. Most doctors recommend seeking treatment if a woman cannot get pregnant or continues to have miscarriages after trying to conceive for 12 months or longer.

For women over 35, many doctors recommend seeking treatment after 6 months of trying to conceive.

Women who do not have regular periods and women with medical conditions that could affect pregnancy should talk to a doctor before trying to get pregnant.

The most common side effects include:

• mood changes, including mood swings, anxiety, and depression
• temporary physical side effects, including nausea, vomiting, headaches, cramps, and breast tenderness
• ovarian hyperstimulation syndrome
• multiple births
• increased risk of pregnancy loss
