Grade Five and Six Sexuality: Questions and Concerns
GRADE FIVE AND SIX SEXUALITY: QUESTIONS AND CONCERNS DAVID CARNEGY B.Ed., University of Lethbridge, 1987 A One-Credit Project Submitted to the Faculty of Education of the University of Lethbridge in Partial Fulfilment of the Requirements for the Degree MASTER OF EDUCATION LETHBRIDGE, ALBERTA April, 1997 Sexuality is an integral part of the personality of everyone: man, woman, and child. It is a basic need and an aspect of being human that cannot be separated from other aspects of human life .. .It is in the energy that motivates us to find love, contact, feel warmth, and intimacy; it is expressed in the way we feel, move, touch and are touched; it is about being sensual as well as sexual. Sexuality influences thoughts, feelings, actions and interactions, and thereby our mental and physical health. Since health is a fundamental human right, so must sexual health also be a basic human right... [including] freedom from fear, shame, guilt, and false beliefs and other psychological factors. (The World Health Organization 1986) "We believe that the facts of one's life are not as important as one's perceptions of those facts." (Christensen and Thomas 1983 pg. 10) Part One Research INTRODUCTION My name is David Carnegy, I am an elementary school teacher and counsellor for Medicine Hat School District #76. One of my assignments every year is to teach the grade five and six "Human Sexuality" program. The Alberta Health Curriculum mandates what teachers should teach to grade five and six students who are 10 to 13 years old. I personally feel that the "Human Sexuality" curriculum is suitable for this age group of children and that it will hopefully help them to better understand their sexuality. -
Unit 1 Structure and Functions of Male Reproductive Organs
UNIT 1 STRUCTURE AND FUNCTIONS OF MALE REPRODUCTIVE ORGANS Structure 1.0 Objectives 1.1 Introduction 1.2 Meaning and Concept of Male Reproductive System 1.2.1 External Reproductive Organs 1.2.2 Internal Reproductive Organs 1.3 Maturation of Male Sex Organs 1.4 Functions of Male Reproductive Organs 1.5 Role of Teachers and Parents 1.6 Let Us Sum Up 1.7 Keywords 1.8 Answer to Check Your Progress 1.9 References 1.0 OBJECTIVES After going through this unit you will be able to: list and describe the organs of the male reproductive system; explain the functions of various male reproductive organs; describe the secondary sexual characteristics in boys; and emphasize that nocturnal emission is a normal phenomenon. 1.1 INTRODUCTION Adolescents are usually shy about asking questions related to their reproductive organs and rely on their peers and other sources which provide incomplete and unreliable information. It is therefore essential, as a responsible adult to open channels of communication and give them correct and complete information. The most important change which occurs during adolescence is related to changes in the reproductive organs. In this unit you will learn about the structure and functions of the male reproductive organs and related changes. This topic is of great concern to adolescents as they have curiosity about the changes in their bodies . This has long term impact on their self-esteem and personality development. In addition, you will undertake several activities, to reflect and understand the structure and functions of reproductive organs of male. 5 Reproductive and Sexual Changes 1.2 MEANING AND CONCEPT OF MALE REPRODUCTIVE SYSTEM One of the most important characteristics that differentiate a living organism from a non – living organism is their ability to reproduce. -

MALE REPRODUCTIVE SYSTEM DR RAJARSHI ASH M.B.B.S.(CAL); D.O.(EYE) ; M.D.-PGT(2ND YEAR) DEPARTMENT OF PHYSIOLOGY CALCUTTA NATIONAL MEDICAL COLLEGE PARTS OF MALE REPRODUCTIVE SYSTEM A. Gonads – Two ovoid testes present in scrotal sac, out side the abdominal cavity B. Accessory sex organs - epididymis, vas deferens, seminal vesicles, ejaculatory ducts, prostate gland and bulbo-urethral glands C. External genitalia – penis and scrotum ANATOMY OF MALE INTERNAL GENITALIA AND ACCESSORY SEX ORGANS SEMINIFEROUS TUBULE Two principal cell types in seminiferous tubule Sertoli cell Germ cell INTERACTION BETWEEN SERTOLI CELLS AND SPERM BLOOD- TESTIS BARRIER • Blood – testis barrier protects germ cells in seminiferous tubules from harmful elements in blood. • The blood- testis barrier prevents entry of antigenic substances from the developing germ cells into circulation. • High local concentration of androgen, inositol, glutamic acid, aspartic acid can be maintained in the lumen of seminiferous tubule without difficulty. • Blood- testis barrier maintains higher osmolality of luminal content of seminiferous tubules. FUNCTIONS OF SERTOLI CELLS 1.Germ cell development 2.Phagocytosis 3.Nourishment and growth of spermatids 4.Formation of tubular fluid 5.Support spermiation 6.FSH and testosterone sensitivity 7.Endocrine functions of sertoli cells i)Inhibin ii)Activin iii)Follistatin iv)MIS v)Estrogen 8.Sertoli cell secretes ‘Androgen binding protein’(ABP) and H-Y antigen. 9.Sertoli cell contributes formation of blood testis barrier. LEYDIG CELL • Leydig cells are present near the capillaries in the interstitial space between seminiferous tubules. • They are rich in mitochondria & endoplasmic reticulum. • Leydig cells secrete testosterone,DHEA & Androstenedione. • The activity of leydig cell is different in different phases of life. -
The Evolution of Intersex Rights in Russia and Reframing Law and Tradition to Advance Reform

INTRODUCTION “Despite all the achievements of civilization, the human being is still one of the most vulnerable creatures on earth.” - Vladimir Putin1 “You are alone, you are not normal”; that is how Aleksander Berezkin learned he was intersex.2 Born in 1984 in Novokuznetsk—a steel-producing town in southwestern Siberia, not unlike Pittsburgh in terms of climate and local economy3—Aleksander lived the life of an ordinary boy until his adolescence, when puberty failed to arrive. “When I was at school, my body looked visibly different from other teenagers,” Aleksander recalled.4 “I had no muscles . [n]o hair on the face. I was skinny and tall. With narrow shoulders and wide hips. Breast glands were enlarged. Sometimes people took me for a girl. I have been bullied and humiliated.”5 Desperate for answers and relief from the merciless taunting and social ostracism, at the age of seventeen Aleksander submitted to a genetic test that revealed the truth. While typical males have the chromosomes XY, Aleksander’s were XXY; he was diagnosed with a variation of Klinefelter syndrome, in which an extra X chromosome inhibits the body’s production of testosterone and leads to the development of stereotypically feminine traits in males.6 But Aleksander received little comfort from his intersex diagnosis, nor Copyright © 2019 by Maggie J.

LECTURE V: Puberty in Males and Females
LECTURE V: Puberty in Males and Females EDITING FILE IMPORTANT MALE SLIDES EXTRA FEMALE SLIDES LECTURER’S NOTES 1 PUBERTY IN MALES AND FEMALES Lecture Five OBJECTIVES ● Define puberty. ● Recognize the physiology of puberty related to changes in hypothalamic-pituitary-gonadal axis. ● Describe the physical changes that occur at puberty in boys and girls. ● Recognize the influencing factors leading to puberty. ● Describe the pathophysiological conditions associated with puberty. Puberty Puberty (AKA: adolescence) is a physiological transition from childhood (juvenility) to adulthood, Accelerated somatic growth. Characteristics of puberty: ● HPG axis matures. ● The primary sexual organs mature (gonads). ● The secondary sexual characteristics develop. ● The adolescent experiences the adolescent growth spurt. ● The adolescent achieves the ability to procreate. Terms & Events GnRH Receptors Sensitivity ● Thelarche: development of breast. ● Pubarche: development of pubic and axillary hair. ● Menarche: the first menstrual period1 . ● Adrenarche: the onset of an increase in the secretion of androgens; responsible for the development of pubic/axillary hair, body odour and acne.2 ● Gonadarche: maturation of gonadal function. Figure 5-1 Increased sensitivity of the GnRH receptors to very low gonadotropins before puberty. Hormonal Changes 3 4 1 Pulsatile secretion of GnRH from the hypothalamus → Increased sensitivity of the GnRH receptors in anterior pituitary. Pulsatile secretion of LH and FSH → Appearance of large nocturnal pulses of LH, during REM sleep5. 2 3 Maturation of primary sexual characteristics (gonads) → Secretion of gonadal steroid hormones (testosterone & estradiol) Appearance of the secondary sex characteristics at puberty (pubic and axillary hair, female breast development, male 4 voice changes)6 FOOTNOTES 1. For unclear reasons, the initial menstrual periods (during the first one-to-two years of puberty) are anovulatory, however this does suggest that the ovary is being made ready for reproduction during the first one-to-two years of puberty. -

ABSTRACT Gender is a psychological component which is given by the society to a person, while sex is a biological component which is awarded by God. However, there are certain conditions in which the biological aspects are put to challenge with the social and psychological aspects of gender. Hermaphrodites are a third gender role, who is neither male or female, man nor woman but contains the element of both. One may question that if they are neither male nor female then who they are and whether they are equally treated in our society. Looking at the challenges faced by hermaphrodites, one need to question what choices these hermaphrodites have in our society. We being a responsible citizen of the society, how can we make their lives less miserable and make them respectable or functional members of our society. -
