What can I do ?

The same applies for both partners:
To back up IVF treatment, you should now pay special attention to maintaining a healthy lifestyle.
Include a lot of fruit and vegetables in your diet, exercise in fresh air and allow yourself enough sleep.
Reduce smoking, or better, give it up completely.
Too much alcohol has a negative impact on fertility, therefore it should be taboo for women during the time of ovulation or implantation of the embryo.

Enjoy your life, meet up with friends, laugh together and do not make love to your partner as though according to a therapy plan, but with passion and desire.
Now and then, try to relax and think of something else.

Leave the responsibility for your desire to have children entirely to us.
