Spermatogenees
Spermatogeneesiks (ladina spermatogenesis) nimetatakse paljudel isastel loomadel (sh meestel) seemnerakkude tekkele viivat rakkude etapilist arenguprotsessi isassuguelundites.[1]
Spermatogenees on kompleksne bioloogiline protsess, mis on hädavajalik paljude loomade suguliseks sigimiseks.

Madudel[muuda | redigeeri lähteteksti]
Suguküpsetel isaste madude seemnerakkude arenguprotsess toimub munandites. Spermatogeneesi kestvus on varieeruv ja oleneb suuresti madude elupaiga temperatuurist - arvatakse, et puhkeseisundis talvituvatel madudel on spermatogenees sesoonne.

Meestel[muuda | redigeeri lähteteksti]
Spermatogeneesi käigus jagunevad diploidsed tüvirakud spermatogoonid algul mitoosi teel, seejärel moodustuvad neist meioosi teel haploidsed spermatiidid, millest küpsevad spermatosoidid. Spermatosoidide küpsemist nimetatakse spermiogeneesiks.
Seemnerakkude etapiline arenguprotsess toimub mitmetes meessuguelundites, sh vääniliste seemnetorukeste iduepiteelis, munandites ja munandimanustes, mis on nimetatud rakkude reservuaar kuni seemepurskeni.
Kogu tsükli pikkus on umbes 70 - 80 ööpäeva.
Spermatogeneesiks on hädavajalik testosterooni olemasolu. Spermatogeneesi hormonaalset ringlust reguleerivad hüpotalamus, ajuripats ja Leydigi rakud.
Algab poistel puberteedieas (spermarhe) ning kestab normaaljuhul elu lõpuni.

Below is an extract from a web page. Evaluate whether the page has a high educational
value and could be useful in an educational setting for teaching from primary school to
grade school levels using the additive 5-point scoring system described below. Points are
accumulated based on the satisfaction of each criterion:
- Add 1 point if the extract provides some basic information relevant to educational top-
ics, even if it includes some irrelevant or non-academic content like advertisements and
promotional material.
- Add another point if the extract addresses certain elements pertinent to education but
does not align closely with educational standards. It might mix educational content with
non-educational material, offering a superficial overview of potentially useful topics, or
presenting information in a disorganized manner and incoherent writing style.
- Award a third point if the extract is appropriate for educational use and introduces key
concepts relevant to school curricula. It is coherent though it may not be comprehensive
or could include some extraneous information. It may resemble an introductory section of
a textbook or a basic tutorial that is suitable for learning but has notable limitations like
treating concepts that are too complex for grade school students.
- Grant a fourth point if the extract highly relevant and beneficial for educational purposes
for a level not higher than grade school, exhibiting a clear and consistent writing style. It
could be similar to a chapter from a textbook or a tutorial, offering substantial educational
content, including exercises and solutions, with minimal irrelevant information, and the
concepts aren’t too advanced for grade school students. The content is coherent, focused,
and valuable for structured learning.
- Bestow a fifth point if the extract is outstanding in its educational value, perfectly suited for
teaching either at primary school or grade school. It follows detailed reasoning, the writing
style is easy to follow and offers profound and thorough insights into the subject matter,
devoid of any non-educational or complex content.

The extract provides detailed information on spermatogenesis, a relevant educational topic, particularly in biology. It introduces key concepts, is coherent, and suitable for learning, although it may be more geared towards higher grade school or even high school levels due to its complexity. The text lacks exercises, solutions, or profound insights but is focused and valuable for structured learning.

Educational score: 4
