V\u00e4lkommen till den manliga fertilitetens v\u00e4rld, d\u00e4r miljontals spermier varje dag ger sig ut p\u00e5 en enast\u00e5ende resa. I testiklarna finns ett komplext n\u00e4tverk av r\u00f6r som kallas tubuli seminiferi<\/strong> ger en fristad f\u00f6r k\u00f6nsceller. Under ledning av hormoner som testosteron f\u00f6rvandlas dessa celler till spermier och utvecklas tills de f\u00e5r den v\u00e4lk\u00e4nda formen av ett \"grodyngel\" - komplett med huvud och svans, vetenskapligt ben\u00e4mnt spermatozoer<\/strong>.<\/p>\n

N\u00e4r spermiecellerna har f\u00e5tt svansar migrerar de till bitestikeln<\/strong>, ett r\u00f6r som ligger intill testiklarna. Under loppet av cirka fem veckor forts\u00e4tter de sin mognadsprocess innan de anl\u00e4nder till s\u00e4desledare<\/strong>eller spermiekanalen.<\/p>\n

Vid upphetsning blandar sig cirka 200-400 miljoner spermier med en vit v\u00e4tska som produceras av prostatak\u00f6rteln<\/strong> och s\u00e4desbl\u00e5sor<\/strong>, skapa s\u00e4desv\u00e4tska<\/a>. Denna kombination resulterar i sperma. Vid samlag sker utl\u00f6sning av sperma genom urinr\u00f6ret. Om ejakulation inte sker bryter kroppen naturligt ner och \u00e5terabsorberar \u00f6verfl\u00f6diga spermier.<\/p>\n

I den h\u00e4r bloggen unders\u00f6ker vi vad som h\u00e4nder med spermierna efter ejakulation - och framf\u00f6r allt hur l\u00e4nge spermierna kan leva.<\/p>\n

Tidpunkten f\u00f6r spermiebildning<\/h2>\n

Keimceller beh\u00f6ver cirka 2,5 m\u00e5nader<\/strong> f\u00f6r att mogna till fullt utvecklade spermier som kan befrukta kroppen. Trots denna l\u00e5nga process producerar m\u00e4n miljontals spermier dagligen. Tack vare denna konstanta produktion f\u00f6rblir en frisk mans fertilitet stabil - \u00e4ven med frekventa ejakulationer.<\/p>\n

Inom en kvinnas b\u00f6rdigt f\u00f6nster<\/strong>kan befruktning ske n\u00e4stan n\u00e4r som helst. N\u00e4r m\u00e4n \u00e5ldras tenderar dock antalet spermier och deras kvalitet att minska, vilket medf\u00f6r en \u00f6kad risk f\u00f6r DNA-mutationer. Livsstils- och h\u00e4lsofaktorer - som kost, r\u00f6kning och stress - kan ocks\u00e5 p\u00e5verka spermiernas r\u00f6rlighet och den totala fertiliteten.<\/p>\n

Utforska spermiers livsl\u00e4ngd<\/h2>\n

Spermiernas livsl\u00e4ngd \u00e4r starkt beroende av milj\u00f6f\u00f6rh\u00e5llandena. Spermier kan f\u00f6rg\u00e5s inom n\u00e5gra minuter eller \u00f6verleva i m\u00e5nader under s\u00e4rskilda omst\u00e4ndigheter. L\u00e5t oss utforska hur.<\/p>\n

Livet utanf\u00f6r kroppen<\/h3>\n

V\u00e4l utanf\u00f6r den manliga kroppen \u00f6verlever spermierna vanligtvis i n\u00e5gra minuter - upp till cirka 30 minuter<\/strong>-beroende av fukt och v\u00e4rme. Utan detta leder exponering f\u00f6r luft till snabb uttorkning och d\u00f6d.<\/p>\n

Men i en f\u00f6rseglad, steril beh\u00e5llare<\/strong>kan spermierna p\u00e5g\u00e5 i flera timmar. Vid ExSeed<\/a>Vi f\u00e5r ofta den h\u00e4r fr\u00e5gan eftersom vi med v\u00e5r Spermatest i hemmet<\/a>Om provet \u00e4r mycket tjockt rekommenderar vi att du l\u00e5ter det vila i 20 minuter f\u00f6r att bli flytande innan du \u00f6verf\u00f6r det till objektglaset. Om provet \u00e4r s\u00e4rskilt tjockt kan ytterligare 10-20 minuter vara till hj\u00e4lp.<\/p>\n

I denna slutna milj\u00f6 f\u00f6rl\u00e4ngs spermiernas livsl\u00e4ngd - men f\u00f6rst efter cirka 60 minuter<\/strong>minskar motiliteten (r\u00f6relsef\u00f6rm\u00e5gan). F\u00f6r korrekta resultat rekommenderar vi att du slutf\u00f6r din analys inom 45 minuter<\/strong> av samlingen.<\/p>\n

Spermier som deponeras p\u00e5 torra ytor - t.ex. h\u00e4nder, lakan eller kl\u00e4der - d\u00f6r inom n\u00e5gra minuter p\u00e5 grund av bristen p\u00e5 fukt.<\/p>\n

Livet i den kvinnliga kroppen<\/h3>\n

N\u00e4r du omsluts av spermiev\u00e4nligt slem fr\u00e5n livmoderhalsen<\/strong>, Spermierna kan \u00f6verleva i upp till fem dagar.<\/a>. Detta slem skyddar och ger n\u00e4ring \u00e5t spermierna och hj\u00e4lper dem att h\u00e5lla sig aktiva och r\u00f6rliga.<\/p>\n

F\u00f6r befruktning m\u00e5ste samlaget ligga i linje med det fertila f\u00f6nstret - dagarna fram till och med \u00e4gglossningen. N\u00e4r spermierna har ejakulerat navigerar de genom livmoderhalsen<\/strong>, livmodern<\/strong>, och \u00e4ggledare<\/strong> f\u00f6r att n\u00e5 fram till \u00e4gget. Endast en liten del av dem klarar sig s\u00e5 l\u00e5ngt, och deras framg\u00e5ng beror p\u00e5 effektiv motilitet.<\/p>\n

Vatten och spermiernas \u00f6verlevnad<\/h3>\n

Spermiernas \u00f6verlevnad beror p\u00e5 fukt och temperatur<\/strong>men befruktning genom vatten (t.ex. pooler eller bubbelpooler) \u00e4r inte m\u00f6jligt<\/strong>.<\/p>\n

Vatten skingrar spermierna och avl\u00e4gsnar dem fr\u00e5n den skyddande milj\u00f6n i sperman. Det \u00e4r dessutom.., kemikalier som klor<\/strong> f\u00f6rst\u00f6r spermier snabbt. \u00c4ven i varmt, kemikaliefritt vatten kan spermier inte leva l\u00e4nge eller befrukta ett \u00e4gg.<\/p>\n

Det frusna riket<\/h3>\n

Under laboratorief\u00f6rh\u00e5llanden kan spermier \u00f6verleva i decennier<\/strong> n\u00e4r de \u00e4r frysta i flytande kv\u00e4ve. Kryogenisk f\u00f6rvaring i spermabanker bevarar spermier f\u00f6r framtida anv\u00e4ndning.<\/p>\n

I Storbritannien kan sperma lagras lagligt i upp till 55 \u00e5r<\/strong> under s\u00e4rskilda omst\u00e4ndigheter, i enlighet med vad som anges i Myndigheten f\u00f6r m\u00e4nsklig befruktning och embryologi (HFEA)<\/a>. Dessa gr\u00e4nser \u00e4r juridiskt definierade snarare \u00e4n biologiskt n\u00f6dv\u00e4ndiga.<\/p>\n

V\u00e5rd av spermiernas h\u00e4lsa<\/h2>\n

Friska spermier \u00e4r avg\u00f6rande f\u00f6r befruktning. \u00c4ven om det \u00e4r viktigt att tajma samlag optimalt \u00e4r det lika viktigt att f\u00f6rb\u00e4ttra spermiernas h\u00e4lsa genom livsstilsval. H\u00e4r \u00e4r n\u00e5gra konkreta steg:<\/p>\n

    \n
  1. Bibeh\u00e5lla optimal temperatur<\/a>:<\/strong> H\u00e5ll testiklarna n\u00e5got svalare - b\u00e4r l\u00f6st sittande underkl\u00e4der och ta pauser fr\u00e5n v\u00e4rmeexponering.<\/li>\n
  2. Sluta r\u00f6ka<\/a>:<\/strong> Att sluta r\u00f6ka f\u00f6rb\u00e4ttrar fertiliteten och f\u00f6rb\u00e4ttrar spermiekvaliteten.<\/li>\n
  3. Begr\u00e4nsa intaget av alkohol<\/a>:<\/strong> F\u00f6r mycket alkohol kan f\u00f6rs\u00e4mra spermiekvaliteten - m\u00e5ttfullhet \u00e4r nyckeln.<\/li>\n
  4. Undvik droger i rekreationssyfte<\/a>:<\/strong> L\u00e4kemedel som t.ex. cannabis<\/a>, anabola steroider och kokain skadar spermieproduktionen och r\u00f6rligheten.<\/li>\n
  5. R\u00e5dg\u00f6r med l\u00e4kare:<\/strong> Kontrollera alltid hur mediciner kan p\u00e5verka fertiliteten.<\/li>\n
  6. Anamma sunda vanor<\/a>:<\/strong> \u00c4t en balanserad kost, h\u00e5ll dig aktiv och h\u00e5ll en h\u00e4lsosam vikt.<\/li>\n
  7. Hantera stress<\/a>:<\/strong> H\u00f6g stress kan f\u00f6rs\u00e4mra spermieproduktionen - ta dig tid att koppla av och vila.<\/li>\n<\/ol>\n

    Med tanke p\u00e5 spermiernas produktionscykel p\u00e5 2,5 m\u00e5nader tar det tid att f\u00f6rb\u00e4ttra spermiernas kvalitet. Varje positiv f\u00f6r\u00e4ndring du g\u00f6r nu st\u00f6der din fertilitet i framtiden - en investering i din h\u00e4lsa och din familjs framtid.<\/p>\n
