1. Human Sexuality

2. Ways Sexuality is Conveyed:
What is Sexuality?
Sexuality is everything about you that relates to, reflects or expresses maleness or femaleness. It is influenced by your sex (gender) and your concepts of gender.
Gender refers to the way people perceive maleness and femaleness to be defined by society.
Your sexuality influences how you think, how you feel about yourself and others, and how you behave. (*you do not need a bf or gf, nor to be sexually active to express your sexuality)
Ways Sexuality is Conveyed:
* the way you dress * the way you move * your gestures
* your facial expressions * body language
* what you say and how you say it
* talking comfortably about your body and feelings
Learning about your sexuality will help you deal with all the changes in a more confident way.

3. Factors Affecting Sexuality Factors Affecting Sexuality
1.) Family
- development of sexuality begins when you’re an infant. The touch of parents, sights and sounds, all contribute to your awareness of your body.
- parents are your first role models of sexuality; they hug and kiss you – they teach you how your bodies can be used to express feelings in positive, healthy ways.
- parents influence understanding of gender roles.
2.) Media
- t.v., music, magazines, movies, newspapers – all convey messages about sexuality.
- conveys both negative and positive messages about sexuality and sexual behavior.
3.) Peers
- you talk to your friends about crushes, ask advice about fashion, personal care, styles, etc.
- peer influence can be both negative and positive. Positive: shape more positive attitudes about oneself. Negative: may influence you to make unhealthy decisions to fit in.
4.) Adult Role Models
- the ones you turn to when you need reliable information about yourself, or about your sexuality.
- parents, other family members, teachers, counselors, doctors, etc. (It’s up to you to sort through the information you receive and act responsibly. You will receive different information because all adults are different.)

4. Sexual Awakening – feelings of sexual attraction
Expressing Sexuality
Because sexuality is part of your personality, it is expressed in many of the things you do such as how you dress, body language, conversation, etc.
Sexual Awakening – feelings of sexual attraction
- this can bring on many concerns about body image and emotions; increased awareness of other people and sexual attraction to others. (varies from person to person as for how and when it will occur.)
Sexual Orientation – sexual preference
- heterosexual – attracted to the opposite sex (a.k.a. straight)
- homosexual – attracted to the same sex (gay/lesbian)
- bisexual – attracted to both sexes
- transgender – gender identity differs from their sex. (internal sense of being a man or a woman
- non-binary a.ka. genderqueer – not exclusively identified as male or female
- asexual – no sexual feelings or desires

5. The Endocrine System (Ch. 18)
The Endocrine system regulates long-term changes in the body such as growth and development.
Endocrine gland – produces and releases chemical substances that signal changes in other parts of the body. (directly into the bloodstream)
Hormones – chemical substances produced by an endocrine gland.

6. The Female Reproductive System
Functions:
Produce sex hormones
Produce eggs
Provide a nourishing environment in which a fertilized egg can develop into a baby.
Structure (Parts):
Ovaries
Fallopian tubes
Uterus
Vagina

8. Female Reproductive System Vocabulary
1.) Ovaries – the reproductive glands in which eggs are produced. (2)
2.) Ova – the female sex cells (ovum = singular form) (eggs)
3.) Fallopian tubes – passageways that carry eggs away from the ovaries. (where fertilization takes place) (2)
4.) Uterus – hollow, muscular, pear-shaped organ where the fertilized egg can develop and grow.
5.) Cervix – the narrow base of the uterus that expands to allow the baby to pass through during birth.
6.) Vagina – (birth canal) a hollow, muscular passage leading from the uterus to the outside of the body.
7.) Estrogen – the sex hormone that activates certain physical changes at puberty and controls the maturation of eggs.
8.) Progesterone – hormone that activates changes to a woman’s reproductive system before and during pregnancy.

9. Female Reproductive System Vocabulary cont’d
9.) Ovulation – occurs about once every month when the ovaries release a mature egg. (occurs when the girl reaches puberty)
10.) Menstrual cycle – during this cycle an ovary releases a mature egg into the fallopian tube, if not fertilized, the uterine lining is shed and a new cycle begins. (also known as a period)
11.) Menopause – the ovaries slow down hormone production, no longer releasing mature eggs and the menstrual cycle stops.

10. Stages of the Menstrual Cycle Stages of the Menstrual Cycle
(refer to Fig. 8 pg. 472)
Days 1-4: The uterine lining is shed during menstruation. (Your cycle starts on the first day of your period)
Days 5-13: An egg matures in one of the ovaries, and the uterine lining thickens.
Days 14-15: The ovary releases the mature egg during ovulation.
Days 16-22: The egg travels through the fallopian tube to the uterus, and the uterine lining continues to thicken.
Days 23-28: The unfertilized egg enters the uterus and leaves the body through menstruation along with the uterine lining.

11. Pathway of the Ovum (egg) Pathway of the Ovum (egg)
Produced in the ovary -
Swept into the fallopian tube by the fimbria -
Fertilization takes place in the fallopian tube -
If fertilized, the egg implants itself in the uterus for development-
If not fertilized, the egg disintegrates and leaves the body through the vagina during the menstrual cycle.

Pathway of Sperm
Sperm are produced in the testes 
Sperm are stored in the epididymus 
Sperm travel through the vas deferens 
They head to the seminal vesicles for nourishing fluid 
The prostate gland and the cowper’s gland add fluid to protect the sperm 
Sperm goes through the urethra and is ejected out of the penis.
