Something tells me no, because I think God created the uterus after the fall when He said that the woman will toil to bring forth child. I don't think that toil was in the original plan. What do you think?
They had FANTASTIC sex before the fall! Adam knew that man would CLING to his wife from the beginning! Adam said so. While naming all the animals Adam would watch animals having sex all the time. He thought of it as a function... no shame before the fall.
They had superb sex! No shame. No one giving them strict judgmental morals to give them hang ups. Perfect tip-top health! ...
God decides when the womb is to be open.
God has the ability to "open and close" the womb causing conception or not.
"Ephraim's glory will fly away like a bird - no birth, no pregnancy, no conception." [Hosea 9:11] (God will prevent it)
"The angel of the LORD appeared to her and said, "You are sterile and childless, but you are going to conceive and have a son." [Judges 13:3]
"Boaz took Ruth and she became his wife. Then he went to her, and the LORD enabled her to conceive, and she gave birth to a son." [Ruth 4:13]
"When the LORD saw that Leah was hated, he opened her womb: but Rachel was barren (womb kept closed by God)." [Genesis 29:31]
"Then God remembered Rachel; he listened to her and opened her womb." [Genesis 30:22]
"But to Hannah he gave a double portion because he loved her, and the LORD had closed her womb." [1 Samuel 1:5]
In Genesis chapter Five men were not having their first son until what we would now call today 'old age'...
ADAM AND EVE WERE EXPERIENCING PHENOMENAL SEX!
Adam knew exactly how he was to function sexually with Eve. Genesis 2:24
