In the context of the Gemara here, what does Mazri'a mean? If mazria means ovulation, how is yotzei dofen excluded? Ovulation takes place in the uterus or maybe fallopian tubes, not in the actual organ itself.

I think that the intent of the Gemara is clear. The wording "Mizra'as" is probably "Agav the Derashah in Maseches Nidah, "Isha Zora'as Techilah...", which does refer to ovulation (roughly). Here, it means Makom Zera, or the path of the Zera.
