[quote=CatholicCid]To my knowledge, an united egg and sperm cell could form life if left in the womb no?
Yes. If it is left in the womb to develop naturally.
A sperm cell or a egg left alone could not correct?
Yes, it is “potential” life but couldn’t all cells classify as that in the general term?
No. Without the joining of egg and sperm there is no new life–no new person formed.
Also, how does the Church not care about them either? I can’t say I’m well voiced in the women’s “cycle” like that, but does not the Church forbid the er… “spilling of seed” from a man outside of sexual intercourse (with intent to create life) with one’s partner?
The “spilling of seed” refers to a man deliberately not fulfilling his husbandly role in reproduction. It does not refer to any release of sperm outside of marital intercourse. Eggs and sperm are only cells like any others apart from each other, like skin cells or any other cells we lose every day.
