I would be interested in seeing some more extensive study with NR on women in their later 30's and 40's specifically around fertility, success around pregnancy and giving birth, breastfeeding, as well as recovery and longer term effects that follow her and the child through developmental years.
Me too. As a woman in that general age range (actually 48 already, yikes) I am keenly aware of such issues -- especially after having multiple IVFs as well as natural conception to eventually have 4 kiddos, my last at age 41, and with the scientific background to understand how the hormone cycle starts to get disrupted with age. So I am very tuned in to hormonal issues around aging, and I definitely see some reversal in that area personally after being on NR since February of this year. The bad news is that women are usually the last to be studied in new medications and I assume supplements, hopefully that will change, but for sure the area around female fertility, aging, and NR seems ripe for study!
(Newbie here, have been enjoying the read). I want to thank you both for posting your interest in upregulation of NAD for fertility! The whole reason I started taking NR and joined this forum is because I'm hoping it will reverse my age-related infertility (I'm 47). I have one living child already and have been trying for a second for the past 6 years. NR has definitely changed my cycle so that it more closely resembles the cycle I had in my 30s, no hormone testing completed yet and not currently attempting pregnancy (trying to give the NR 4+ months to work).
My interest was prompted by some current research Sinclair is doing which was not designed with fertility in mind (I believe they are looking for changes to mitochondria and muscle) but which produced an interesting fertility outcome: menopausal mice (equivalent to age 50-60) became fertile again and had healthy litters. Sinclair is also an advisor to OvaScience, a fertility startup that seeks to restore ovarian reserve and egg quality through stem cell technology. Through OvaScience, he also has a patent application that uses NR or NMM in a supplement or IVF medium to restore egg quality prior to IVF. I'm sure many of you are very familiar with this research already, but just in case not, here are links to a video and the patent application:
This is the video:
An observation of repair of mouse ovaries from NAD supplementation. The outcome was unintentional as they normally use male mice. Here is a link to a video and transcript of an interview from a television program called Catalyst, with primary researcher Dr. David Sinclair discussing it (beginning around 7:14 into the video):

Here is the patent application for a supplement that could be taken as a pill to restore ovarian function and egg quality in older women or used as a kind of medium in IVF to repair eggs and embryos.

This is the most interesting part of the patent (OSCs are egg stem cells):
"Raising NAD+ levels in cells and in vivo dramatically increased mitochondrial function and mitochondrial content, which is generally recognized as a major determinant of female fertility, metabolic health, brain function, cardiovascular health and glucose metabolism/type II diabetes. OSCs and oocytes treated with an NAD precursor (e.g. nicotinamide riboside ie. "NMN") had increased NAD+, NAD+:NADH, and mitochondrial DNA content.
To determine whether increasing NAD+ levels had an effect on oocyte production, spontaneous oocyte formation was assayed. Each well of a 24-well plate was seeded with 25,000 OSCs. The number of oocytes formed and released into the medium per well was assessed the second day after seeding as well as the designated time points after NMN treatment. NMN treatment increased the rate of egg formation (EFA). Based on these results, compounds and genes that increase NAD+ in vivo or in vitro are expected to reduce or reverse infertility associated with mitochondrial damage, energetic defects, and aging of the ovary in female subjects.
NMN and other compounds that increase NAD+ levels are useful for increasing fertility or otherwise reducing or reversing infertility in a female subject."
