- Selen przyczynia się do prawidłowej spermatogenezy (tworzenia plemników)
1. Charakterystyka żywności / składnika
The food constituent that is the subject of the health claims is selenium, which is a well recognised nutrient and is measurable in foods by established methods.
Selenium occurs naturally in foods and is authorised for addition to foods and for use in food supplements (Annex I of the Regulation (EC) No 1925/20064 and Annex I of Directive 2002/46/EC5). This evaluation applies to selenium naturally present in foods and to those forms authorised for addition to foods and for use in food supplements (Annex II of the Regulation (EC) No 1925/2006 and Annex II of Directive 2002/46/EC).
The Panel considers that the food constituent, selenium, which is the subject of the health claims is sufficiently characterised.
2.7. Spermatogeneza (tworzenie plemników) (ID 396)
The claimed effect is “spermatogenesis”. The Panel assumes that the target population is the general male population.
The Panel considers that normal spermatogenesis is beneficial to human health.

Selenium is an essential trace element. Twenty-five selenoprotein genes have been identified in the human genome (Kryukov et al., 2003). Selenoproteins have a number of functions, comprising various catalytic roles (glutathione peroxidases, thioredoxin reductases, and iodothyronine
deiodinases), structural roles, detoxifying functions (e.g. selenoprotein P) and storage and transport activities. Selenium is present in foods mainly as selenomethionine and selenocysteine. It is absorbed efficiently by the intestine over a wide range of concentrations and across a variety of different molecular forms (Bates, 2005).
3.7. Spermatogeneza (tworzenie plemników) (ID 396)
The sperm mitochondrial capsule selenoprotein has a structural as well as an enzymatic role, and it is responsible for both the maintenance of motility and the structural integrity of the tail of the sperm. Both human and other mammals exhibit reduced sperm motility and increased sperm rupture under conditions of low selenium supply (Bates, 2005).
The Panel concludes that a cause and effect relationship has been established between the dietary intake of selenium and normal spermatogenesis. However, the evidence provided does not establish that inadequate intake of selenium leading to impaired spermatogenesis occurs in the general EU population.
4.4. Spermatogeneza (tworzenie plemników) (ID 396)
The Panel considers that the following wording reflects the scientific evidence: “selenium contributes to normal spermatogenesis”.
5. Warunki i możliwe ograniczenia stosowania oświadczenia
The Panel considers that in order to bear the claims a food should be at least a source of selenium as per Annex to Regulation (EC) No 1924/2006. Such amounts can be easily consumed as part of a balanced diet. The target population is the general population. Tolerable Upper Intake Levels (UL) have been established as 300 µg/day for adults and for pregnant and lactating woman. For children and adolescents UL were established as 60 µg/day for 1-3 years, 90 µg/day for 4-6 years, 130 µg/day for 7-10 years, 200 µg/day for 11-14 years and 250 µg/day for 15-17 years (SCF, 2000).
