  • Title: [Reproductive function of the male rat after a flight on the Kosmos-1129 biosatellite].
    Author: Serova LV, Denisova LA, Apanasenko ZI, Kuznetsova MA, Meĭzerov ES.
    Journal: Kosm Biol Aviakosm Med; 1982; 16(5):62-5. PubMed ID: 6890601.
    Abstract:
    Male rats that were flown for 18.5 days on Cosmos-1129 were mated postflight with intact females. The mating 5 days postflight when the ejaculate consisted of spermatozoids that were exposed to zero-g effects in the mature stage yielded the litter which lagged behind the controls with respect to the growth and development during the first postnatal month. The mating 2.5-3 months postflight when the ejaculate consisted of spermatozoids that were exposed to zero-g effects at the stem cell stage yielded the litter which did not differ from the control.
