Try to cut the squash into evenly sized pieces. We know cutting up winter squash, especially butternut squash, can be tricky. (Donât worry; in our recipe below, we share how we do it). We find that separating the thinner end from the round, wider end makes things much easier.
A ripe egg can live in the outer edge of a fallopian tube for 12-24 hours. If there are sperm in the womans cervix or if the couple has intercourse while an egg is alive in a fallopian tube, the sperm can travel up through the uterus and the fallopian tube and try to fertilize the egg.
So it is possible for some sperm to survive that long in the uterus, usually in the cervical mucus or the fallopian tubes. But that is not typical. Most sperm die in the uterus within 24-48 hours after ejaculation, and the more time has passed after ejaculation, the less likely is the fertilization of the egg.
