▷

Track Ovulation

Investigate Short Luteal Phase

So if I sit across from somebody and I just say, are your cycles regular? and they say yes, and we carry on, I've missed the fact that they actually have a shortened luteal phase, and that warrants further investigation.”
▷
1:25:03
Target Intercourse to the Fertile Window

Avoid NSAIDs Outside Menstrual Period When Trying to Conceive
Behaviors
“So that's why we recommend, and a fun fact, or important to know, if you're trying to get pregnant, you can take those medications only when you're on your period.

Avoid Cannabis

1:57:32

2:08:35
Human Growth Hormone

▷
2:20:49

▷
2:27:58
Cut Back on Red Meat
