Embryo is a 1976 science fiction horror film directed by Ralph Nelson and starring Rock Hudson alongside Barbara Carrera, with a cameo appearance by Roddy McDowall. It deals with the mental and physical consequences of growing a human embryo in an artificial uterus.
Dr. Paul Holliston (Hudson) is a geneticist who has been living alone in his rambling clinic, which he operates out of his home, after losing his wife in a car crash. This leads to his feeling constant pangs of guilt from his sister-in-law Martha Douglas (Diane Ladd), who has become his assistant.
One night, Holliston runs over a pregnant doberman dog. The dog is fatally injured, but Holliston manages to save one of her unborn puppies by gestating it in an artificial uterus. Because the device still requires nutrients to be supplied by the mother, he must drastically shorten the gestation period: to this end, he uses an experimental growth hormone made from human placental lactogen, which speeds up the embryo's growth.
Nothing has come of these
Enhancing hours
Of talking and talking
Without having said a thing
So I’ll be the one to masterfully
Break the ice again
It seems we’re getting closer
To falling in
We’re drowning with every word said
Can either of us
Distinguish fear from yearning
How clever we are to speak in a place such as this
Speaking of the end
Speaking on our bed
Do these sheets conceal you
Go ahead
And live your dreams
In your embryo sleep
Just gravitate towards me
Shut your mouth
Don’t you speak out loud
