About this stage

A note from Dr. Rumpa.

Preconception health is the work both partners do in the 90 days before trying to conceive, the window when egg quality and the 74 day spermatogenesis cycle are still modifiable. This journey covers what the evidence supports, what it does not, and what to actually change.

Start with the framework. A 90 day plan before trying to conceive maps week by week for couples, and the 90 day window explains why the preconception phase matters most. The fertility diet section moves past trends to the Mediterranean diet fertility evidence, an honest list of foods to avoid for sperm health, and the caffeine and alcohol TTC limits for both partners.

Supplements get dose level detail. Prenatal vitamins, when to start and which to pick, prenatal vitamins with folic acid vs methylfolate, the preconception supplements stack worth taking, vitamin D and fertility, CoQ10 supplement for fertility, plus the male fertility supplements pillar: zinc for sperm health with selenium and vitamin E, CoQ10 and male fertility, and the 74 day supplement cycle for how improve sperm health.

Then the harder levers. Weight and fertility numbers and BMI, losing weight with PCOS for fertility, PCOS insulin resistance fertility, myo-inositol and D-chiro inositol, the PCOS diet supplements protocol, exercise and fertility dose, stress and fertility plus sleep, hot tubs and saunas sperm risk, lifestyle habits vs supplement for sperm health, and endocrine disruptors fertility evidence.

Just the protocol, the doses, and the decision points.
