As with many carnal matters, the much-ballyhooed sex-scene episode of Glee caused a rise -- ratings-wise, anyway -- on Tuesday night. And a modest boost for CBS' NCIS was enough to make it the top-rated show of the evening and help boost the network to an overall win Tuesday.

Meanwhile, ABC's new comedy Man Up continued to lose ground, according to preliminary numbers.

Glee, on Fox at 8, grew 3 percent to a 3.1/8 and 6.8 million total viewers. But New Girl at 9 dipped 3 percent to a 3.5/9 and 6.8 million total viewers. The network's night ended with distressing news -- with Raising Hope at 10 dropping 16 percent, taking a 2.1/5 and 4.6 million total viewers.

NCIS, on CBS at 8, inched up 5 percent over last week's performance for a 4.1 rating/11 share in the adults 18-49 demographic, with 20.3 million total viewers, which also made it the most-watched program of the evening. NCIS: LA the following hour performed flat with last week for a 3.4/8 and 15.5 million total viewers.

The new drama Unforgettable closed the night with a 4 percent boost, taking a 2.4/7 and 11.6 million total viewers. Overall, the network averaged a 3.3/9 and 15.8 million total viewers, which made it the highest-rated and most-watched network of the night.

ABC experienced a night of modest downturns, with Last Man Standing at 8 slipping 4 percent to a 2.6/7 and 9.2 million total viewers. Man Up at 8:30 slid 6 percent to a 1.7/5, a series low, and 6.2 million total viewers. The Dancing With the Stars results show at 9 was down 4 percent from last week, taking a 2.7/7 and 14.8 million total viewers. The network rounded out the night with the special In the Spotlight With Robin Roberts: All-Access Nashville, which drew a 1.7/5 in the demo and 8.6 million total viewers.

NBC had a mixed evening, with The Biggest Loser at 8 crawling up 4 percent for a 2.4/6 and 6.8 million total viewers, and Parenthood at 10 dropping 9 percent for a 2.0/6 and 5.2 million total viewers.
