Amma da yawa daga cikinmu har yanzu suna gaskanta da wasu kyawawan maganganu marasa kimiya, tatsuniyoyin maniyyi da suka daɗe. Anan akwai goma sha biyu daga cikin abubuwan da aka fi sani.

Nope.

Na farko, maniyyi baya yin iyo da gaske - a mafi yawancin. Yawancin lokaci ikon motsi na maniyyi, wanda aka sani da motsi, ana rarraba shi zuwa ɗayan ƙungiyoyi uku:

• motsi na ci gaba: motsi a hankali cikin madaidaiciyar layi ko manyan da'ira

A cikin wata makala ga Aeon, Robert D. Martin ya bayyana hanyar a matsayin "mafi kama da ƙalubalen cikas na soji" da ƙasa da daidaitaccen tsere. Kuma koda hakane, maniyyi yana buƙatar sama da ɗan ƙarfafawa daga tsarin mace mai amfani don tabbatar sun isa layin ƙarshe.

A zahiri, mafi yawan aikin motsi ana yin su ne da ƙwayoyin mahaifa. Yana hada maniyyi har zuwa bututun mahaifa, zuwa kwan.

2. Maniyyin maniyyi shine mafi yawan maniyyi

Maniyyin maniyyi ba lallai bane yana nufin maniyyi mai kauri. Yawancin lokaci yana nufin akwai tarin ƙwayoyin maniyyi ko yawan adadin maniyyi mai tsari mara tsari. Har yanzu suna bukatar taimako daga tsarin haihuwa na mata don su zauna lafiya.

Lokacin da maniyyi ya shiga cikin farji, sai su hadu da lakar mahaifa. Cusarjin bakin mahaifa yana yin abubuwa biyu: kariya da ƙin yarda. Yana kare maniyyi daga sinadarin farji kazalika yana kin maniyyi wanda sifofin sa da motsin su zai hana su kaiwa kwai.

Yadda tsarin haihuwa na mata ke taimakawa maniyyi:

1. Erfin mahaifa - nama tsakanin farji da mahaifa - ganuwar ta fadada.
2. Crypts, ko wuyan mahaifa, suna girma cikin lamba kuma suna ƙaruwa cikin girma don adana ƙarin maniyyi.
3. Katangar bakin mahaifa yana fitowa saboda haka yana da sauki maniyyi ya wuce.

3. Maniyyi yana rayuwa ne na ɗan lokaci kaɗan bayan fitarwa

Ba koyaushe ba! Tsawon rayuwa ya dogara da inda maniyyi ya sauka bayan inzali.

Maniyyin da yake sanya shi cikin farji bayan fitar maniyyi na iya yin kwana biyar. Wannan shi ne saboda sakamakon kariya na ƙashin mahaifa da kumburin mahaifa.

Amma idan maniyyi yana da damar bushewa, asalima suna mutuwa. Fitar maniyyi wanda ya sauka akan sanyi, busassun abubuwa na iya mutuwa bayan fewan mintoci kaɗan - duk da cewa ba safai suke iya ɗaukar tsawon minti 30 ba. Suna iya mutuwa ko da sauri a cikin wanka mai zafi ko baho mai zafi saboda zafi ko sunadarai a cikin ruwan.

4. Maniyyi yana bukatar tafiya kai tsaye don kwan

Yana da kyakkyawar doguwar tafiya zuwa ƙwai. Yayin saduwa, lokacin da maniyyi ya fita daga azzakari, basa zuwa kai tsaye zuwa mahaifa.

A cikin wannan kwas din, wasu kwayoyin maniyyi sun hada da kwayoyin halittar oviduct a cikin bututun mahaifa ko kuma adana su a cikin kananan dakunan da ake kira crypts har zuwa lokacin haduwar farko: kwayayen.

5. Maniyyi ya kasance mai haihuwa da lafiya ga dukkan rayuwar mutum

Daya daga cikin tsofaffin tatsuniyoyi shine cewa yayin da akwai iyakantattun kwai (wanda yake gaskiyane), ana samun maniyyi a wadatar rayuwa.

Ba da sauri ba.

Samun maniyyi, ko kwayayen maniyyi, yana faruwa har abada, amma inganci da motsin maniyyi yana raguwa da shekaru.

Haka kuma tsofaffi maza na iya wucewa ga childrena childrenan su maye gurbi, game da su, a cewar wani binciken Icelandic.

Amma tufafi yana da (kusan) tasiri akan maniyyin ku.

Kuma sami wannan: Jiki na iya ramawa don ƙarin zafi na kwayar cutar ta hanyar sakin extraan ƙaramin ƙwayar maniyyi-mai haifar da hormone mai motsa jiki.

Don haka, 'yan dambe ne kawai kadan more maniyyi-m. Sanya abin da zai sa ka cikin kwanciyar hankali.

8. Kowane maniyyi yana da lafiya kuma yana iya aiki

Nisa da shi.

Kuma daga wannan kashi arba'in, ba duka ke zuwa ƙwai ba.

Kuma daga cikin maza 42 sun gano cewa aƙalla kashi 17 cikin ɗari na samfuran pre-cum suna cike da ƙwayoyin maniyyi masu amfani.

Don haka koda kuna amfani da hanyar cirewa, akwai karamar dama cewa wasu maniyyi zai iya sakin jiki ya haifar da juna biyu.

10. Yawan maniyyi ya fi kyau yayin kokarin daukar ciki

A ka’ida, kwaya daya tak da ke da kwaya daya tak ke da izinin yin takin kwaya daya, wanda ke haifar da ci gaban amfrayo. Bayan maniyyi na farko ya karye ta bangaren sunadaran da ke kusa da kwan, wannan layin yana toshe karin maniyyi daga wucewa.

Amma idan maniyyi da yawa sun isa kwayayen, biyu - ko sama da haka, a wasu lokuta - maniyyi zai iya ratsawa ta wannan layin kuma ya kawo ƙarshen ƙwan. Wannan ana kiransa polyspermy.

Ka riƙe wannan a zuciya idan kai da abokin tarayya sun yanke shawarar amfani da ƙwayoyin in vitro (IVF) don ɗaukar ciki. Saboda IVF yana kange ayyukan haifuwa da yawa wadanda ke iyakance yawan maniyyi ya isa ga kwan, maniyyinka baya bukatar samun miliyoyin maniyyi ya zama mai haihuwa.

11. Maniyyi shine sinadarin gina jiki

Wannan sanannen tatsuniya ce mai yuwuwa ana yi mata wargi koyaushe. Amma ya kamata ka shanye maniyyi sama da 100 don ganin duk wata fa'ida ta gina jiki daga gare ta.

Ari da, wasu mutane suna da alamun rashin lafiyan zuwa maniyyi, don haka shan shi ba koyaushe ake ba da shawarar ba.

12. Abarba tana sanyawa maniyyinka ya dandani

Ba abarba ce kawai da mutane ke cewa suna da kyau don ƙoshin ruwan maniyyi ba, amma babu ɗayan tatsuniyoyin da suka shafi kimiyya.
