The number of new members marks an increase from last year's Winter rush process, during which five fraternities extended 20 bids.
"This was another strong Winter rush season," Brown said in an email. "We're pleased so many men were able to find houses."
Seven fraternities held Winter rush this term, including Sigma Alpha Epsilon fraternity, which has historically has not held rush during the Winter.
Of the 25 new members, Alpha Chi Alpha fraternity saw five men shake out and extended three bids. Sigma Phi Epsilon fraternity saw 17 men, 16 of whom shook out, and nine to whom they offered bids.
Zeta Psi fraternity extended seven bids, out of a pool of nine men who rushed and eight who shook out.
Sigma Alpha Epsilon saw 13 men over the two nights of rush, 12 of whom shook out, and offered a total of five bids. Gamma Delta Chi fraternity gained one new member.
Phi Delta Alpha, Psi Upsilon, Alpha Delta, Theta Delta Chi, Chi Heorot, Beta Alpha Omega, Bones Gate and Kappa Kappa Kappa fraternities did not hold rush this term, according to Brown.
Though Winter rush officially takes place on Saturday and Sunday, most of the fraternities participating only held one night of rush on Saturday.
"If you don't give any callbacks then you don't need to have a second night," IFC recruitment coordinator Cole Adams '13 said.
Fraternity representatives said that Winter recruitment this term was comparable to past terms, since rush is a standard process.
"It's a tradition, so there is not a lot of planning involved," Adams said.
Zete rush chair Steve Muenzen '14 said that the fraternity had a very successful Winter recruitment process.
"The brothers are all looking forward to getting to know our excellent Winter class, which is largest we have had in years," Muenzen said in an email.
Chi Gam is similarly pleased with their new pledge class, Chi Gam rush chair Yobiel Kelati '15 said.
Winter rush differs from Fall rush because fewer students participate, Kelati said. Many fraternities fill up their pledge class during Fall rush and do not accept new members in the Winter, according to Adams.
SAE decided to hold Winter rush this term because there were students who were interested in joining the house, but were taking an off-term in the Fall, according to president Michael Fancher '13. This is the first time since 2010 that SAE has held Winter rush.
"Rush went great," Fancher said. "We all really like our '15s, both in the Fall and this Winter."
Although Tri-Kap historically has held Winter rush in the past, the fraternity decided not to do it this year, Tri-Kap president Paul Wagdalt '13 said in an email.
"We were more than happy with how our '15 class shaped up in the Fall," he said.
