natalia yurievna ragozina -lrb- -rrb- , better known as natascha ragosina , is an undefeated retired professional boxer who spent much of her career ranked as the top female super middleweight in the world .
though born in kazakhstan -lrb- formerly a part of the soviet union -rrb- and currently residing in germany , she competed professionally for russia and is of russian descent .
she is the longest reigning wba female super middleweight champion and wbc female super middleweight champion .
at the time of her retirement , she held all major female super middleweight titles and two heavyweight belts : iwbf -lrb- international women 's boxing federation -rrb- super middleweight title wibf -lrb- women 's international boxing federation -rrb- super middleweight title wiba -lrb- women 's international boxing association -rrb- super middleweight title global boxing union female super middleweight title wbc female super middleweight title wba female super middleweight title wibc super middleweight title wibf -lrb- women 's international boxing federation -rrb- heavyweight title wbf -lrb- women 's boxing federation -rrb- heavyweight title on march 15 , 2008 , ragosina defeated bermudian teresa perozzi to win a record 7 championship belts in a single fight , breaking giselle salandy 's previous record of 6 belts won in a single fight .
however , two weeks later , salandy - a light middleweight boxer - defeated karolina lukasik in a match with 8 titles on the line to regain her record for titles won in a single fight .
on july 11 , 2008 , ragosina won a controversial decision against conjestina achieng , winning a close but unanimous decision .
one judge awarded ragosina the fight by a single round , and the other two judges had ragosina winning by a two round margin .
some boxing observers believe achieng won the fight .
perhaps due to the controversial decision in the first fight , the two had a rematch on november 28 , 2008 , which ragosina won more convincingly .
on december 19 , 2009 , ragosina defeated heavyweight world champion pamela london by knockout to add two heavyweight championships to her resume - the wibf women 's international boxing federation heavyweight title and the world boxing federation heavyweight title .
despite a 65-pound weight disadvantage -lrb- ragosina weighed in at 172 , compared to london 's 237 pounds -rrb- , the 5 ' 11 '' ragosina used her reach and quickness to knock out london in round 8 .
this brought ragosina 's record to 22-0 , including a 16-0 record in title fights .
ragosina is also a single mother .
she considers herself good friends with fighters fedor emelianenko , alexander povetkin , and nikolai valuev .
