Imiphumela utshwala ngesikhathi kwenzeka lokhu amaseli lwegciwane nokukhiqizwa

utshwala Ethyl has nethonya elilimaza hhayi kuphela kwi-germ cells wabantu, kodwa futhi phezu ubulili nezindlala ngokwabo. Izinkinga ukukhiqizwa kabusha e Amadoda nabesifazane abathola lezi kudla utshwala zihluke kakhulu ngenxa ukwakheka germ cells imithetho osobennstey. Kulula utshwala ukudakwa ukubekezelela amaseli ubulili besilisa, isimiso sezakhi zofuzo okuthi lanxa ezilimele ngaphansi kwethonya ethanol, kodwa akhiqizwa amadoda ukuphila kwabo konke. Ngokuvamile, engena esikhundleni ephelele isidoda inqubo entsha kuthatha izinyanga ezintathu.

Nokho, ingozi main utshwala amadoda akuyona ukushintsha isakhiwo sakhe ubulili amaseli, futhi kokunqotshwa kwe gonads. Lemigwamanda abe othize liningi igazi uhlelo, elifana nalelo ebuchosheni, yingakho utshwala siphela egazini, angahlala isikhathi eside lapho. Ngenxa yalokhu, kukhona ukonakala we kokumethemba sperm cell, obangela uketshezi of hormone (testosterone). Ngakho, indoda, isikhathi eside, njengoba beye babhekana utshwala ukudakwa, has a awokuthi germ cells yayo uzobe kukhiqizwa ngesikhathi esisodwa abanokukhubazeka okuthile. Ngaphezu kwalokho, ngenxa yokungabi bikho hormone wesilisa kakhulu ukushintsha imikhuba yayo, kuyoba khona zokugula kwesimiso sokuzala, kuze nokuvusa induku.

Kunengqondo ukuphetha ngokuthi kungaba kubi kunokwakuqala imiphumela yokweqisa ophuzweni ingeyomzimba wesilisa? Kodwa abesifazane lapho umuntu enezinkinga ezihambisana ukulimala utshwala germ cells kanye nezindlala lapho esidabukisayo, hhayi ikhumbula yokuthi ukuluthwa utshwala owesifazane ethuthuka ngokushesha okungaka futhi aselapheki. Iqiniso lokuthi insikazi ubulili amaseli (ova) akhiwa phakathi nenkambo yokuphila, kokubili amadoda, futhi kakade ngesikhathi zokuzalwa 'agcinwe "kuze nokuvuthwa okugcwele ukukhulula phakathi lesizalo ingaphakathi (nge-ovulation). Ngenxa yalokhu, ngisho olulodwa nophuzo oludakayo kungase (Nokho alibalulekile) ukwandisa amathuba nokuba ingane engenampilo. Kodwa kuyangabazeka noma kukhona owesifazane ofuna ukuhlola lokhu kungenzeka ku ngokwayo (ngisho noma ayidluli angu). Uma owesifazane ophuza utshwala njalo, lokhu okungenzeka kwandisa izikhathi eziningi.

Umthelela utshwala insikazi wokuzala kanye nokuya endocrine uhlelo fanekiso nalokho okuchazwe ingeyomzimba besilisa. Umehluko amanga kuphela yokuthi abesifazane ziye zanciphisa inani lama-hormone zesifazane egazini ngenkathi okwandisa lokuhlushwa testosterone, ngokuvamile ethakwa ngumuntu wesifazane. Ngenxa yalokhu, ukushintsha ukubukeka kwaso, kuza masculinization (female izici ukulahlekelwa) kanye nezinguquko zokuziphatha. Ikakhulukazi, izinguquko nokuziphatha kwabantu besifazane maqondana nengane ilahlekelwa eziningi imizwelo engokwemvelo elihlobene ne-ukunakekelwa yenzalo.

Ngaphezu kwalokho, uhlelo zokuzala ukuphuza abesifazane njalo obala amandla okubhubhisa utshwala, ngenxa okuyinto ngqo kukhulisa ematfuba ukungazali, kwabadala kulezi abesifazane kwenzeka eminyakeni engu-15 ngaphambi kwe-enempilo.

Ngokuphathelene izingane ezizalwa abazali utshwala, ngokuvamile beye baligcina ukukhubazeka ezithile, ngezinye izikhathi sifinyelela phezulu sengozini. I obujwayelekile fetus alcohol syndrome, bembonisa ukubambezeleka ukuthuthukiswa engqondweni nasemzimbeni ingane.
