In fact, hav­ing more than 20 male part­ners DOU­BLED the risk of prostate can­cer.

The find­ings are from the Prostate Can­cer & En­vi­ron­ment Study in which 3,208 men were asked to an­swer ques­tions about their life­style and sex lives.

Pro­fes­sor Marie-Elise Par­ent, from the Univer­sity of Mon­treal, said: “It is pos­si­ble that hav­ing many fe­male sex­ual part­ners re­sults in a higher fre­quency of ejac­u­la­tions, whose pro­tec­tive ef­fect against prostate can­cer has been pre­vi­ously ob­served in co­hort stud­ies.”

The study found that men who were vir­gins were almost twice as likely to be di­ag­nosed with prostate can­cer as those who were sex­u­ally ex­pe­ri­enced.

Com­pared with those who had only had one part­ner, men who had slept with also 19% less likely to de­velop an ag­gres­sive type of can­cer.

Ac­cord­ing to one the­ory, large num­bers of ejac­u­la­tions may re­duce the con­cen­tra­tion of can­cer-caus­ing sub­stances in pro­static fluid, a con­stituent of se­men.

They may also lead to fewer crys­tal-like struc­tures in the prostate that have pre­vi­ously been as­so­ci­ated with prostate can­cer.

The age at which men first had sex, and the num­ber of times they had been in­fected by a sex­u­ally trans­mit­ted dis­ease, had no bear­ing on prostate can­cer risk.

A to­tal of 12% of the group re­ported hav­ing had at least one sex­u­ally trans­mit­ted in­fec­tion (STI) in their lifetime.


While hav­ing one male part­ner did not af­fect can­cer risk, hav­ing more than 20 dou­bled the chances of a di­ag­no­sis and it in­creased the risk of a less ag­gres­sive can­cer type five-fold.

Prof Par­ent said: “It could come from greater ex­po­sure to STIs, or it could be that anal sex pro­duces a phys­i­cal trauma to the prostate.” THREE Libyan sol­diers who are train­ing in Bri­tain have been charged with sex­u­ally as­sault­ing women.

The trio, who are based at Bass­ing­bourn Bar­racks, Cambs, were ar­rested after three at­tacks on three women in Cam­bridge on Sun­day night.

One woman was at­tacked in the first in­ci­dent at 10.30pm and two more were at­tacked just 10 min­utes later.

Khaled El Az­ibi, 18, and Ibrahim Naji El Maarfi, 20, have both been charged with two counts of sex­ual as­sault, while Maarfi has also been charged with one count of ex­po­sure.

Mo­hammed Ab­dal­salam, 27, is charged with one count of sex­ual as­sault and one count of threat­en­ing be­hav­iour against a po­lice of­fi­cer.

The sol­diers were also ques­tioned about six other at­tacks on women in Cam­bridge city cen­tre on Oc­to­ber 17.

Up to 2,000 Libyan troops are ex­pected to be trained at Bass­ing­bourn over the next 15 months.
