Mating is the kiss of death for female worms
12/19/13 - Princeton University researchers, led by Coleen Murphy, Associate Professor of Molecular Biology and the Lewis-Sigler Institute for Integrative Genomics, found that male sperm and seminal fluid trigger pathways that cause females to dehydrate, prematurely age, and die.
The presence of male sperm and seminal fluid causes female worms to shrivel and die after giving birth, Princeton University researchers reported in the journal Science. The demise of the female appears to benefit the male worm by removing her from the mating pool for other males.
"Their lifespans are cut by about a third to a half," said senior author Coleen Murphy, an associate professor of molecular biology and the Lewis-Sigler Institute for Integrative Genomics.
