In this FAMM Research Series episode, Lisa explores groundbreaking research on the role of retinoic acid—the active form of vitamin A—in spermatogenesis, testosterone production, and overall male fertility. Discover why vitamin A may act as the biological "on/off" switch for sperm production, and how nutrient-dense foods like liver could play a pivotal role in male preconception care.

| 0:49.4 | Today I'm sharing a brand new episode in our FAM research series, and I'm going to be tackling the role of vitamin A in sperm production. |
| 0:53.4 | I think this topic is really important and really |
| 0:55.6 | interesting because the research is astounding, yet it's not something that I hear a lot of people |
| 1:01.9 | talking about, the importance of vitamin A, especially as it relates to sperm production |
| 1:06.4 | and fertility in general. So while we'll be focusing today on male reproduction, particularly sperm |
| 1:12.0 | production and testosterone and the role of vitamin A in that process, know that vitamin A plays |
| 1:18.3 | an equally significant role in female reproduction. And there's a lot of research through |
| 1:23.5 | animal studies that sheds light on why this nutrient is so important. So today we'll be going |
| 1:29.3 | through a paper. It's called the role of retinomic acid in spermatogenesis and its application |
| 1:34.6 | in male reproduction. So this study is a narrative review. It's not a clinical trial. It pulls together findings from animal models, cell studies, human data, and it really maps out the role of retinoic acid, which is the active form of vitamin A in spermatogenesis. So while this study goes into a lot of detail, it's really high level. |
| 2:02.3 | If you were to pull it and try to read it, there's a lot of, a lot of terms, let's just say, |
| 2:07.3 | because it goes into a lot of really specific detail. What we'll be doing today is just kind of |
| 2:11.4 | getting a feel for how essential this nutrient is in this process, how it works, and we'll also be talking about then |
| 2:20.8 | the role of nutrition and the potential for vitamin A to really support and improve sperm |
| 2:26.9 | production in men. So a little bit of background information. I've spoken about vitamin A and |
| 2:32.4 | written about it in both the fifth vital sign as well as real food for fertility. |
| 2:38.0 | We shared some research and some studies. |
