Which two rheumatoid diseases are more prevalent in men than women?

The choice of ankylosing spondylitis and reactive arthritis as the answer hinges on the understanding of gender prevalence in these diseases.

Ankylosing spondylitis is predominantly seen in men, with studies indicating that men are affected about three times more frequently than women. This condition is a type of inflammatory arthritis that primarily affects the spine and the sacroiliac joints, leading to pain and stiffness.

Reactive arthritis, while it can affect both genders, is also observed more frequently in men, particularly those in certain age groups. It typically arises following an infection in another part of the body, such as the urinary tract or gastrointestinal system.

In contrast, rheumatoid arthritis and systemic lupus erythematosus (lupus) are autoimmune diseases that predominantly affect women, making those selections incorrect. Psoriatic arthritis does exhibit a more balanced gender distribution but is not primarily male-biased like ankylosing spondylitis or reactive arthritis. Osteoarthritis is also not characterized by a significant gender disparity and tends to affect both sexes similarly. Gout typically has a higher prevalence in men but is not classified as a rheumatoid disease; instead, it is a type of inflammatory arthritis due to hyperuricemia.

Therefore, ankyl
