We know the sun is good for our emotional wellbeing but can it also affect fertility? New research says yes! According to Austrian physicians Barbara Obermayer-Pietsch and Elisabeth Lerchbaum vitamin D plays a role in human fertility. Deficiency of vitamin D can cause infertility among women and men. They found that low levels of vitamin D often lead to too much testosterone, which therefore could increase the risk of infertility among women. Also, when men are given extra vitamin D they produce more testosterone subsequently affecting the semen quality.

Researchers said, “It may not be that controlling vitamin D is the ultimate answer to fertility problems but it could be a very cheap and simple solution at least in some cases.”

Sources of Vitamin D:

• Fatty fish species, such as:

• Catfish, 85 g (3 oz) provides 425 IU (5 IU/g)

• Salmon, cooked, 100 g (3.5 oz) provides 360 IU (3.6 IU/g)

• Mackerel, cooked, 100 g (3.5 oz), 345 IU (3.45 IU/g)

• Sardines, canned in oil, drained, 50 g (1.75 oz), 250 IU (5 IU/g)

• Tuna, canned in oil, 100 g (3.5 oz), 235 IU (2.35 IU/g)

• Eel, cooked, 100 g (3.5 oz), 200 IU (2.00 IU/g)

• A whole egg provides 20 IU if egg weighs 60 g (0.333 IU/g)

• Beef liver, cooked, 100 g (3.5 oz), provides 15 IU (0.15 IU/g)

• Fish liver oils, such as cod liver oil, 1 Tbs. (15 ml) provides 1360 IU (90.6 IU/ml)

• UV-irradiated mushrooms and yeast are the only known vegan significant sources of vitamin D from food sources. Exposure of portabella mushrooms to UV provides an increase of vitamin D content in an 100-g portion (grilled) from about 14 IU (0.14 IU/g non-exposed) to about 500 IU (5 IU/g exposed to UV light).
