Though the chances of natural pregnancy with Low Ovarian Reserve (otherwise Diminished Ovarian reserve) is very slow, there are still people who got pregnant with DOR (Diminished Ovarian Reserve). Some of the real life stories are denoted below
Success Story 1: Someone had Diminished Ovarian Reserve and the IVF told they should froze her eggs before December but she had become naturally pregnant even when the IVF facility was not sure. She recounted her story in reddit over here
Success Story 2: She was 35 and she was told it’s difficult to conceive on her own as she had DOR (Diminished Ovarian Reserve) but she also become naturally pregnant!
Success Story 3: She had irregular period and she was nearly going to into early menopause and she was over 30 years of age but she also conceived naturally without any IVF
All the above success stories indicate that it’s also possible to become naturally pregnant without any IVF as all these women though they had DOR (Diminished Ovarian Reserve) they conceived naturally. As it all the sperm needs is only one egg to fertilize to get you pregnant so there might be still a chance for someone with DOR to get conceive naturally
