The reproductive system is the human organ system responsible for the production and fertilization of gametes (sperm or eggs) and, in females, the carrying of a fetus. Both male and female reproductive systems have organs called gonads that produce gametes.
he reproductive system is a collection of internal and external organs — in both males and females — that work together for the purpose of procreating, according to the Cleveland Clinic. Due to its vital role in the survival of the species, many scientists argue that the reproductive system is among the most important systems in the entire body.

Reproduction is the process that continues life on Earth
Males and females each have structures specialized for their roles in reproduction.
Hormones are the key to how the human reproductive system functions,
Sex hormones are necessary for the development of sexual characteristics, such as breast development in females and facial hair growth in males.
Hormones from the pituitary gland also begin the production of eggs in females and sperm in males. Eggs and sperm transfer hereditary information from one generation to the next.
The female reproductive system provides several functions.
The ovaries produce the egg cells, called the ova or oocytes.
The oocytes are then transported to the fallopian tube where fertilization by a sperm may occur.
The fertilized egg then moves to the uterus, where the uterine lining has thickened in response to the normal hormones of the reproductive cycle.
Once in the uterus, the fertilized egg can implant into thickened uterine lining and continue to develop.
If implantation does not take place, the uterine lining is shed as menstrual flow.
In addition, the female reproductive system produces female sex hormones that maintain the reproductive cycle.
During menopause, the female reproductive system gradually stops making the female hormones necessary for the reproductive cycle to work. At this point, menstrual cycles can become irregular and eventually stop.
One year after menstrual cycles stop, the woman is considered to be menopausal.

Human reproduction is any form of sexual reproduction resulting in human fertilization. It typically involves sexual intercourse between a man and a woman. During sexual intercourse, the interaction between the male and female reproductive systems results in fertilization of the woman's ovum by the man's sperm.

The human body’s major systems, the reproductive system is the one that differs most between sexes, and the only system that does not function until puberty.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
3. SISTEM REPRODUKSI PRIA
Sistem reproduksi pria
meliputi organ-organ
reproduksi,
spermatogenesis, dan
hormon-hormon pada pria.
Organ reproduksi pria
dibedakan menjadi dua
bagian, yaitu organ
reproduksi dalam dan organ
reproduksi luar.
4. Organ Reproduksi Dalam
Organ reproduksi
dalam pria terdiri
dari testis, saluran
pengeluaran, dan
kelenjar asesoris.
5. Testis
Testis atau gonad jantan berbentuk oval
dan terletak di dalam skortum atau kantung
pelir. Fungsi testis secara umum merupakan
alat untuk memproduksi sperma dan hormon
kelamin jantan yang disebut testostern.
8. Epididimis
Merupakan saluran berkelok-kelok di
dalam skortum yang keluar dari testis.
Epididimis berjumlah sepasang di sebelah
kanan dan kiri. Epididimis berfungsi sebagai
tempat penyimpanan sementara seperma
sampai seperma menjadi matang dan
bergerak menuju vas deferens.
9. • Vas deferens
Vas deferens atau
saluran sperma
merupakan saluran lurus
yang mengarah ke atas
dan merupakan lanjutan
dari epididimis. Vas
deferens berfungsi sebagai
saluran tempat jalannya
sperma dari epididimis
menuju kantung semen
(kantung mani) atau
veskula seminalis.
10. • Saluran ejakulasi
Saluran ejakulasi
merupakan saluran
pendek yang
menghubungkan
kantung semen dengan
uretra. Saluran ini
berfungsi untuk
mengeluarkan sperma
agar masuk ke dalam
uretra.
11. • Uretra
Uretra merupakan
saluran akhir reproduksi
yang terdapat di dalam
penis. Uretra berfungsi
sebagai saluran kelamin
yang berasal dari
kantung semen dan
saluran untuk
membuang urin dari
kantung kemih.
13. Organ Reproduksi Luar
Organ reproduksi luar pria
trdiri dari penis dan skrotum.
• Penis terdiri dari tiga rongga
yang berisi jaringan spons. Dua
rongga yang terletak di bagian
atas berupa jaringan spons
korpus kevernosa. Satu rongga
lagi berada di bagian bawah
yang berupa jaringan spons
korpus spongiosum. Korpus
spongiosum membungkus
uretra. Uretra pada penis
dikelilingi oleh jaringan erektil
yang rongga-rongganya banyak
mengandung pembuluh darah
dan ujung-ujung saraf perasa.
14. • Skrotum merupakan kantung
yang di dalamnya berisi testis.
Di dalam skrotum juga
terdapat serat-serat otot yang
berasal dari penerusan otot
lurik dinding perut yang
disebut otot kremaster. Otot
ini bertindak sebagai
pengatur suhu lingkungan
testis agar kondisinya stabil.
Proses pembentukan sperma
atau spermatogenesis
membutuhkan suhu yang
stabil, yaitu beberapa derajat
lebih randah daripada suhu
tubuh.
15. Hormon Pada Pria
• Testosteron
Hormon ini penting bagi tahap
pembelahan sel-sel germinal untuk membentuk
sperma, terutama pembelahan meiosis untuk
membentuk spermatosit sekunder.
16. • FSH (Follicle Stimulating Hormone)
FSH juga disekresi oleh sel-sel kelenjar
hipofisis anterior dan berfungsi menstimulasi
sel-sel sertoli. Tanpa stimulasi ini, pengubahan
spermatid menjadi sperma (spermiasi) tidak
akan terjadi.
17. • Hormon pertumbuhan
Hormon pertumbuhan
(seperti juga sebagian besar
hormon yang lain) diperlukan
untuk mengatur fungsi
metabolisme testis. Hormon
pertumbuhan secara khusus
meningkatkan pembelahan awal
pada spermatogenesis.
18. SISTEM REPRODUKSI WANITA
Sistem reproduksi wanita meliputi organ
reproduksi dan proses oogenesis, fertilisasi,
kehamilan, dan persalinan. Organ reproduksi
wanita terdiri dari organ reproduksi dalam dan
organ reproduksi luar.
19. Organ Reproduksi Dalam
Organ reproduksi dalam
wanita terdiri dari ovarium dan
saluran reproduksi. Ovarium atau
indung telur berjumlah sepasang,
berbentuk oval dengan panjang
3-4 cm. Umumnya setiap
ovarium menghasilkan ovum (sel
telur) setiap 28 hari. Ovarium
juga menghasilkan hormon
esterogen dan progesteron.
Ovum yang dihasilkan ovarium
akan bergerak ke saluran
reproduksi. Saluran reproduksi
wanita terdiri dari oviduk, uterus,
dan vagina
20. • Oviduk
Oviduk (tuba falopii) atau
saluran telur berjumlah
sepasang dengan panjang
sekitar 10cm. Oviduk
berfungsi untuk
menyalurkan ovum (sel
telur) dari ovarium
menuju uterus.
21. • Uterus
Uterus atau rahim
(kantung peranakan)
merupakan rongga
pertemuan oviduk kanan
dan kiri yang berbentuk
seperti buah pir dan
bagian bawahnya
mengecil disebut serviks
atau leher rahim. Uterus
berfungsi sebagai tempat
perkembangan zigot
apabila terjadi fertilisasi.
22. • Vagina
Vagina merupakan
saluran akhir dari saluran
reproduksi bagian dalam
pada wanita. Vagina
memiliki dinding yang
berlipat-lipat dengan
bagian terluar berupa
selaput berlendir, bagian
tengah berupa lapisan
otot, dan bagian terdalam
berupa jaringan ikat
berserat.
23. Organ Reproduksi Luar
Organ reproduksi luar
pada wanita berupa vulva.
Vulva merupakan celah paling
luar dari organ kelamin wanita.
Pada vulva bermuara dua
saluran, yaitu saluran uretra
dan saluran kelamin. Pada
daerah dekat saluran ujung
vagina terdapat himen atau
selaput dara. Himen
merupakan selaput mukosa
yang banyak mengandung
pembuluh darah.
24. Proses Terjadinya Menstruasi
Menstruasi terjadi jika ovum tidak dibuahi
oleh sperma, sehingga korpus luteum akan
menghentikan produksi hormon estrogen dan
progesteron. Turunnya kadar estrogen dan
progesteron menyebabkan lepasnya ovum dari
dinding uterus yang menebal. Lepasnya ovum
tersebut menyebabkan endometrium sobek atau
meluruh. Peluruhan pada endometrium yang
mengandung pembuluh darah menyebabkan
terjadinya pendarahan pada fase menstruasi.
Pendarahan ini biasanya berlangsung selama lima
hari. Volume darah yang dikeluarkan rata-rata
sekitar 50 mL.
25. Gangguan pada Sistem Reproduksi
Manusia
• Gangguan pada Sistem Reproduksi Wanita
Kanker Vagina
Kanker Serviks
Kanker Ovarium
Endometriosis
26. • Gangguan pada Sistem Reproduksi Pria
Hipogonadisme
Kriptorkidisme
Uretritis
Prostatitis
Orkitis
27. KESIMPULAN
Sistem reproduksi pria meliputi organ-organ
reproduksi, spermatogenesis, dan hormon-hormon
pada pria. Organ reproduksi pria dibedakan menjadi
dua bagian, yaitu organ reproduksi dalam dan organ
reproduksi luar.
Sistem reproduksi wanita meliputi organ reproduksi
dan proses oogenesis, fertilisasi, kehamilan, dan
persalinan. Organ reproduksi wanita terdiri dari
organ reproduksi dalam dan organ reproduksi luar.
