Not only did nature intend for women and men to meet and mate; couples were so composed that they could reside contentedly for the rest of their lives.
The mating couple is therefore completely vulnerable to lions and other dangers during this "lock" period.
Irrespective of male body size, the mating couples were frequently surrounded by the other females, apparently shortening the mating duration compared with matings in the absence of other females (Enigl & Schausberger, 2004; Gotoh & Tsuchiya, 2008).
Couples were collected from cages for each treatment group sequentially for 30 60 min. A few minutes after they completed mating, couples were placed on ice and females transferred to 200 µl PBS buffer with proteinase inhibitor for storage at –20°, dissections at a later stage and body size measurement.

When female and male flies begin mating, the couples were carefully transferred to small cages and raised for 12 h, avoiding disturbing.
Me and a couple of mates were quite taken aback by it.
For each couple, the mating success was assessed checking for the presence of viable daughters in the offspring.
However, the length of time the couple remained in the mating posture was significantly shorter in plugged females than in females without a plug.
This happens, and people don't talk about it: just like you turn 28 and realise all your mates are happily coupled up and have been for years and you, the last remaining all-singing, all-shagging singleton tearaway, get invited to four weddings in one summer and have a massive Tinder panic when you realise you've got a +1 to each and nobody to +1 with.
