Scrotal hyperthermia : Obesity causes a lot of fat accumulation in the thighs, groin, and scrotal region. This in turn raises the temperature in the scrotum which is then transmitted to the testis, affecting its function

Chronic epididymitis: As obesity itself is a chronic inflammatory state, obese people are seen to have inflammation/ swelling in the epididymis which is closely associated with the testis. This inflammation affects the sperm function.

Erectile dysfunction: Obesity can cause erectile dysfunction due to the oxidative stress inflammation, insulin and leptin resistance associated with obesity. Erectile dysfunction could be a major cause for male infertility

Sperm DNA fragmentation : Increase in adipocytes leads to increase in peripheral aromatization of testosterone to estradiol. Increase in adipocytes also leads to increase in proinflammatory cytokinesis and increased reactive oxygen species also called ROS.  This ROS in turn leads to Sperm DNA fragmentation & and sperm epigenetic changes.

Central and peripheral resistance : Obesity can also lead to central and peripheral resistance. There is reduced GNHR from the hypothalamus in the brain which disrupts the pituitary axis which in turn results in decreased LH and FSH resulting in decreased testosterone and spermatogenesis. Which in turn affects fertility.
