Tom Arnold Reveals Dax Shepard Almost Donated Him And His Wife Sperm

Tom Arnold was a guest on "The Wendy Williams Show" Thursday (Jan. 30) and made some pretty astounding revelations.

Arnold told Williams that he and his fourth wife, Ashley, struggled for years to conceive because of his "very low sperm count." Arnold then said that his friend, Dax Shepard, offered to be their sperm donor and his wife, Kristen Bell, even agreed.

Ultimately, Arnold, 54, and his wife didn't use Shepard's help and in April of last year, welcomed baby Jax into the world. "We are still in a bit of shock," Arnold told People after welcoming the baby boy. "It has been a long journey and the healthy birth of our son is a miracle."
