Masero e spermatogenesis

Kana uchitarisa zvikonzero zvekushaya mwana muvakaroorana, vose vari vaviri vanoongororwa. Nyaya huru yekuedzwa kwevarume munyaya iyi inonzi spermogram. Rudzi urwu rwekutsvakurudza rwakave nechinangwa chekugadzirisa muyamuenzaniso we ejaculate vasati vemazuva masero ezvirwere, izvo mumatambudziko akawanda ane zvisizvo muurongwa. Kunyanya kubhadharwa kunobhadharwa kumasero e spermatogenesis, ayo anowedzera kuva spermatozoa.

Iko kuumbwa kwevarume zvepabonde zvepabonde?

Asati ataura nezvehuwandu hwemasero epepermatogenesis mune chimiro kana chiyero chinogona kuvapo mumharapamu, ngatimbokurukurai muchiitiko chekukura kwe spermatozoon.

Nokudaro, kuumbwa kwevarume nemasero emadzimai muvakomana kunotanga pamakore anenge gumi uye kunopera kusvika pakukwegura, muupenyu hwose hwemunhu. Panguva imwecheteyo, zvakajairika kufungidzira kuti nguva yechirungu che spermatogenesis inenge mazuva makumi manomwe.

Maumbirwo emasero ehurume anotanga zvakananga mukati me convoluted seminiferous tubules yematete. Chimwe chezviyo zvavo zvinosanganiswa ne-septum inopinda mukati memakumi maviri ehafu. Mune chimwe chezvikamu zvakati pamwe zve spermatogenesis zviripo, uye muchipiri - spermatogonia, iyo inowedzera kupa spermatozoa. Kazhinji, imwe nyanzvi inosvika mabhiriyoni akadaro masero.

Ndezvipi masero anenge asina kufema uye kuti anofanira kunge ane zvakadini mu spermogram?

Sezvo mutemo, kuvapo kwenhamba yakawanda yemasero e spermatogenesis kunotungamirira kukurudzirwa kwematambudziko mumarume. Ndosaka chiratidzo ichi ndechimwe chezvinhu zvakakosha pakuongorora migumisiro yekudzidza kwakadaro.

Mazuva mashoma masero e spermatogenesis anowanzonzi spermatogenic. Izvi zvinosanganisira:

• spermatogonia - stem masero, ayo ndiwo maitiro ekuumbwa kwe spermatocytes;
• spermatocytes 1 (ramba uri mumasosis semugumisiro wekusagona kupatsanurwa kwema cell) uye 2 mirairo (shandisa 1 prophase meiosis, pedza kupatsanurwa kwekutanga, kuumba semugumisiro 2 spermatocytes mumwe nomumwe);
• spermatids (ine haploid set ye chromosomes uye mushure mekushanduka kwemaitiro kunoshandurwa kuva spermatozoa).

Zvakakosha kuziva kuti masero asina kusangana e spermatogenesis anowanikwa mune chero upi zvawo. Saka, mumushambadzi maitiro avo haafaniri kudarika mamiriyoni mashanu / ml emuviri. Zvisinei, dzimwe nguva, muhupo hwekuputsa, huwandu hwechiratidzo ichi hunowanikwa katatu. Zvidzidzo zvenguva pfupi zvakaratidza kuti chiratidzo ichi hachisi chikuru chekufungidzira kukosha.

Zvinonyanya kukosha pakugadzirisa chinokonzera chirwere chacho ndezvemasero emasero mu sperm cell, akadai se leukocytes, kana kuti, panzvimbo yavo, sautrophils. Nhamba yacho yose haifaniri kudarika 1 mamiriyoni / ml. Kana zvisina kudaro, pane kukurudzirwa kwekuputsa kwakadaro saukoukospermia, iyo inokanganisa hutachiwana hwemajeri emajeri kuti aite.

Zvakadini kana spermiogram ichiratidza nhamba inowedzera yemasero e spermatogenesis?

Sezvatotaurwa pamusoro apa, kunyange mumasero epermermogogenesis haagoni kuvapo pane samples ye ejaculate. Zvisinei, kana nhamba yavo yose inodarika mamiriyoni mashanu / mami, ipapo munyaya iyi vanotaura nezvehutachiona.

Rudzi urwu rwekuputsa ndiko kukundikana kwegadziriro yekuumbwa kwepermatozoa. Somugumisiro weizvi, mbeu inowanikwa muhurosi nehutsika husingarevi morphology (chimiro): kusavapo kwema flagella, kaviri flagellum, musoro maviri, nezvimwewo. Izvozvo zvinonzi spermatozoa hazvikwanisi kudiridza, nekuda kwekutyora kwemotokari yavo.

Mumamiriro ezvinhu akadaro, murume anorayirwa kurapwa, iyo inoshandiswa pakusimudzira spermatogenesis, iyo, kutanga kune yose, inowanikwa kuburikidza nekugadzirwa kwemishonga yemadhoni.

Nokudaro, zvinogona kutaurwa kuti kuvapo mune spermogram yemasero masero e spermatogenesis haisi kuputsa kana maitiro avo asingasviki mutemo wakagadzwa.
