Here is an interesting article from the website Daily Life which may explain some feelings that couples going through infertility treatment are going through.
They are based on what has been shown with any other grieving process, like the five stages identified by Kubler-Ross, the progression of infertility emotions has stages as well.
“When you’re having trouble having a baby, there may be a lot to grieve. You grieve your ovaries, which work only some of the time. You grieve your partner’s sperm for being too few or poor swimmers. You grieve the entire process; all of the tests, the diagnoses, the waiting. Things many may never need to think about, you’ve obsessed over. Good grief.”
I recommend this article as it might provide some insight and help you through the emotional aspects of infertility.
