Vedci analyzovali spr\u00e1vanie spermi\u00ed, proces oplodnenia a prv\u00e9 f\u00e1zy v\u00fdvoja embry\u00ed u \u013eud\u00ed, my\u0161\u00ed a prasiat. Podmienky beztia\u017ee simulovali pomocou \u0161peci\u00e1lneho pr\u00edstroja naz\u00fdvan\u00e9ho klinostat, ktor\u00fd rot\u00e1ciou eliminuje vplyv gravit\u00e1cie. V\u00fdsledky v\u00fdskumu boli publikovan\u00e9 v prest\u00ed\u017enom vedeckom \u010dasopise Communications Biology<\/a>.<\/p>\n

Vedci v\u0161ak objavili n\u00e1dejn\u00e9 rie\u0161enie. Po pridan\u00ed horm\u00f3nu progester\u00f3nu sa schopnos\u0165 \u013eudsk\u00fdch spermi\u00ed orientova\u0165 v\u00fdrazne zlep\u0161ila.

Na druhej strane, dlh\u0161ie vystavenie beztia\u017ei, pribli\u017ene 24 hod\u00edn, viedlo k spomaleniu v\u00fdvoja a ni\u017e\u0161iemu po\u010dtu buniek v embry\u00e1ch.
