Men in Pain (Traditional Chinese: 男人之苦) is a TVB modern drama series broadcast in June 2006.

Hong Tin-Yam (Damian Lau) is happily married to his second wife Wong Dak-Kiu (Louisa So), but one day he discovers that he cannot perform in the bedroom.

He asked a female friend, Au Yeung Lei-Lei (Akina Hong), to help him out and confirmed that he was in fact impotent.

On the other hand, Tin-Yam's son, Hong Sai-Hei (Ron Ng) spends a night with Dak-Kiu's student, Ko Fun (Toby Leung) during an excursion.

Ko Fun is stressed with handling the baby and her school courseload, while Sai-Hei is worried that he cannot afford to put food on the table.
