Dr. Robert Winston may be a member of Britain’s House of Lords, but he’s no stuffed shirt. As host of this eight-hour documentary miniseries (the last four hours air Aug. 1-2), he puts his own sperm under a microscope, allows a leech to suck his arm, endures a dinghy ride in choppy waters to simulate morning sickness and generally throws himself into the task of enlightening viewers on the workings of the human body. Intimate Universe uses photographic and medical-imaging techniques so extraordinary you’ll swear a major-studio film crew set up in someone’s innards.

Bottom Line: Biology class was never this much fun
