Eating right increases male fertility
Pravilna prehrana zmanjšuje moško neplodnost
Infertility, defined as the failure to achieve pregnancy after one year of unprotected intercourse, affects 10 to 20 percent of couples. At least 40 percent of the time, the woman is unable to conceive because her male partner has a physical problem. As with female fertility, male fertility is affected by what foods and nutrients are eaten--although some of the specifics are different. Following is a review of the fertility factors that seem most important for men.
Neplodnost definoramo kot neuspela zanositev po enem letu nezaščitenih spolnih odnosov. Prizadetih je 10 do 20 odstotkov parov. Med temi je najmanj 40 odstotkov tistih parov, med katerimi ženske ne zanosijo zaradi moške neplodnosti. Tako kot ženska neplodnost, je tudi moška povezana s prehrano – čeprav so nekatere specifike drugačne. V nadaljevanju je pregled prehranskih faktorjev, ki vplivajo na moško plodnost.
*Alcohol is a male reproductive tract toxin. Consumed in a large enough quantity over a long enough period of time, alcohol can cause infertility.1 Fortunately, findings from animal research suggest that the damage alcohol causes to sperm is at least partially reversible if males infertile from alcohol avoid drinking it for a "moderate" period of time.2
*Alkohol je strup za moško reproduktivnost. Če moši v daljpšem obdobju zaužije večje količine alkohola, lahko to vpliva na plodnost. Na žalost testi raziskav kažejo, da škodljivi učinki alkohola niso zanemarljivi tudi v primeru, če moški pije alkohol občasno.
*Vitamin B12 deficiency also plays a role in fertility. Here's how: Intrinsic factor is a substance necessary for the proper absorption of B12. When an aging stomach lining fails to secrete enough intrinsic factor, a B12 deficiency results causing serious or pernicious anemia. Eventually, this condition can cause infertility in both men and women. In one study, infertility caused by pernicious anemia was shown to be reversible with vitamin B12 injections.3
*Vitamin B12 – njegovo pomanjkanje tudi igra pomembno vlogo v plodnosti. Poglejmo kako: bistven factor je substanca, ki je potrebna za vsrkavanje vitamina B12. Ko želodčna sluznica ne vsebuje dovolj lastnega izločka, je pomanjkanje vitamina B12 lahko vzrok marsikakšni želodčni težavi. Načeloma lahko to povzroči neplodnost pri obeh spolih, moških in ženskah. V neki raziskavi je bilo dokazano, da so z injekcijami vitamina B12 izboljšali plodnost.
*Vitamin C has long been important to fertility. In recent years, we have become increasingly aware of the destructive effects of free radicals, which contribute to the development of many disorders. Vitamin C helps protect sperm against free radical damage.5
*Vitamin C je bil dolgo zelo pomemben za plodnost. V zadnjih letih pa se še bolj zavedamo njegove uničevalne moči nad prostimi radikali, ki prispevajo k razvoju mnogih motenj oziroma okvar. Torej vitamin C pomaga ščititi spermo proti poškodbam, ki jih povzročajo prosti radikali.
Several studies have found vitamin C supplementation not only increases sperm counts but improves various measures of sperm health.6 The vitamin's therapeutic effects are not limited to changes seen in the laboratory. In one study, two months after 30 infertile but otherwise healthy men began receiving 1 g of the vitamin daily, all of their wives had become pregnant, whereas none of the wives of a similar group of men who received a placebo had become pregnant.7
Več raziskav je pokazalo, da vitamin C, ne samo da povečuje število spermijev, temveč izboljšuje več različnih merjenj kvalitete spermijev. Laboratorijska terapija z vitaminom C nima omejitev. V neki raziskavi je sodelovalo 30 neplodnih toda drugače fizično zdravih moških. Dva meseca so prejemali 1 g vitamina C dnevno. Po dvomesečni terapiji so vse njihove žene zanosile, pri čemer nobena od žena v podobni skupini (možje niso prejemali ničesar), ni zanosila.
*Zinc is among the most important nutrient minerals in regards to male fertility. Zinc levels in the seminal plasma (the fluid in which the sperm exist) are directly related to sperm mobility,8 and dietary zinc restriction reduces both sperm count9 and seminal plasma volume.10 Moreover, infertile men with azoospermia (absence of living sperm),11 as well as those with oligospermia (low sperm count),12 may have decreased seminal zinc levels.
* Cink je eden od najpomembnejših prehrambenih mineralov ki pripomorejo k moški plodnosti. Nivo cinka v semenski plazmi (tekočina v kateri plavajo spermiji) je direktno povezan z mobilnostjo spermijev in pomanjkanje cinka zmanjšuje oboje: število spermijev in količino semenske tekočine. Poleg tega so ugotovili, da imajo moški v katerih izlivu ni živih spermijev in tudi tistih, ki imajo majhno število spermijev, v semenski plazmi nizek nivo cinka.
Several clinical trials have found zinc supplementation to be an effective fertility treatment. In one study, 14 infertile men with unexplained low sperm counts (below 40 million/mL) received 220 mg of zinc sulfate daily. After four months, there were significant improvements in sperm count and in the number of progressively motile and normal spermatozoa--and the wives of two men conceived.13
Več kliničnih poskusov je dokazalo, da je prisotnost cinka zelo pomembna za moško plodnost. V neki raziskavi je sodelovalo 14 moških z nerazložljivo nizkim številom spermijev (manj kot 40 milionov/ml). 4 mesece so prejemali po 220 mg cinkovega sulfata dnevno. Po štirih mesecih se je pokazalo občutno povečanje števila spermijev, povečanje gibljivosti spermijev in povečanje količine semenske tekočine – kar je bilo dovolj, da sta dve ženi zanosili.
The results of other studies suggest treatment of a low initial plasma testosterone14 or surgical correction of a varicocele (abnormal dilation of spermatic cord veins) prior to zinc supplementation15 increase the chances of success. In this latter study, of the entire group of infertile men who received zinc, only those who had a varicocelectomy prior to starting zinc supplementation had significant improvements in sperm counts and mobility; in other words, sperm did not improve unless the men had both surgery and zinc supplementation.
Rezultati ostalih raziskav pri moških z operativnim posegom pri diagnozi varikokele (zabrazgotinjeni semenovodi) kažejo na to, da dodajanje cinka poveča možnosti za uspeh. V tej, kasnejši raziskavi se je pokazalo, da se je pri moških s težavami v plodnosti in ki so prejemali dodatni odmerek cinka, povečalo število in mobilnost semena. Z drugimi besedami: kvaliteta sperme se je izboljšala le v primeru, da je bil opravljen operativni poseg in terapija z dodajanjem cinka.
These simple, inexpensive and safe nutritional interventions can often transform an infertile couple into proud parents, they should be routinely considered in all infertility treatment programs.
Našteti enostavni, poceni in varni prehrambeni dodatki lahko velikokrat pomagajo neplodnim parom, da postanejo ponosni starši, hkrati pa lahko upajo na uspešnejše terapije za zdravljenje neplodnosti.
