This document provides an overview of human reproductive anatomy and processes. It describes the key external and internal organs of both the male and female reproductive systems. It also summarizes gamete formation through spermatogenesis and oogenesis, the hormonal control of the reproductive cycles, conception and early embryonic development, menopause, and key differences between male and female reproductive cycles and hormone regulation.
this is only for study purpose. students can refer it any time. it is easy to understand by every one. it help to improve knowledge regarding reproductive male system- both external, internal & supporting structure.

This PPT covers Anatomy and Physiology of Male Reproductive System. It includes anatomy of male reproductive organs, spermatogenesis and hormonal regulation of testis
The human reproductive system includes the male reproductive system which functions to produce and deposit sperms; and the female reproductive system which functions to produce egg cells, and to protect egg cells, and to protect and nourish the fetus until birth.
The reproductive tissues of male and female humans develop similarly in utero until about the seventh week of gestation when a low level of the hormone testosterone is released from the gonads of the developing male. Testosterone causes the primitive gonads to differentiate into male sexual organs. When testosterone is absent, the primitive gonads develop into ovaries. Tissues that produce a penis in males produce a clitoris in females. The tissue that will become the scrotum in a male becomes the labia in a female. Thus the male and female anatomies arise from a divergence in the development of what were once common embryonic structures.
1. Spermatogenesis (Spermatocytogenesis, Spermiogenesis, Spermiation, Shape and function of cells inside the Testis, Semen and sperm structure, Sperm journey after synthesis to outside)
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 - A detailed study ( medical information)martinshaji
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.
By the end of this section, you will be able to:
Describe human male and female reproductive anatomies
Describe spermatogenesis and oogenesis and discuss their differences and similarities
Describe the role of hormones in human reproduction
Describe the roles of male and female reproductive hormone
The reproductive events in humans include formation of gametes (gametogenesis), i.e., sperms in males and ovum in females, transfer of sperms into the female genital tract (insemination) and fusion of male and female gametes (fertilisation) leading to formation of zygote.
this is a long study on all aspects of human reproduction & most asked questions about human reproductive system ( medical information ).

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.
