This is from memory..do not take as fact:...Laci had one ovary and Scott was reported to cooperate in being home when her"fertile" cycle was happening as they had not been successful in getting Laci pregnant...He told one of Laci's relatives he had kinda hoped for infertility.
I believe there was speculation early that Scott didn't believe he was the father but rumors were wild then...I recall the DNA of the baby settled that rumor.
I believe all of what you said here is true. Some of it is borne out by the testimony: Mark G. spoke to the clinic people about how she had an ovulation predictor, and they agreed. The part about one ovary is true, too; I think that may have been mentioned in the testimony too.
And the part about "kinda hoping for infertility" was testified to.
