3. MALE REPRODUCTIVE SYSTEM
• The male sex organ are mostly outside the body.
A man or a boy has a finger-shaped organ called
Penis between his legs.
• Behind the penis hangs a small sac called the
scrotum that contains two oval-shaped organs
called the testicles or testes.
• The testicles produce and store the male sex cells
or gametes called sperms.
• The testicles consist of complicated system of
tubes called the vas deferens that produced the
whitish fluid called semen.
5. FEMALE REPRODUCTIVE SYSTEM
• The female reproductive parts are found
mostly inside the body.
• The folds of skin is called vulva covers the
opening to a narrow canal called vagina.
• The organs called ovaries produce and
store the female sex cells called eggs or
ovum.
• After ovulation, the eggs enter a narrow
tube called the Fallopian tube.
6. FEMALE REPRODUCTIVE SYSTEM
• Usually, only one egg
• at a time is released as a part of a monthly
process called the menstrual cycle.
• During the menstrual cycle, changes take
place in the uterus.
8. INTRODUCTION
• GONADS
• > reproductive glands like testis and
ovary produce gametes begin to form
until about eight week of embryonic
development.
• DURING THE EARLY STAGES:
• > the embryonic reproductive structures
of males and females are alike and are
said to be in the indifferent stages.
9. INTRODUCTION
When the primary reproductive
structures are formed, development of
the accessory structures and external
genitalia begins.
The formation of male and female
structure depends on the presence of
TESTOSTERONE.
10. INTRODUCTION
Usually , once formed, the embryonic
testes release testosterone, and the
formation of the duct system and
external genitalia follows.
In the case of female embryos that
forms ovaries.
It will cause the development of the
FEMALE DUCT and EXTERNAL GENITALIA
since testosterone hormone is not
developed.
11. INTRODUCTION
Any intervention with the normal
pattern of sex hormone production in
the embryo results in strange
ABNORMALITIES.
If the embryonic testes fail to produce
testosterone, a genetic male develops
the FEMALE ACCESSORY structures and
EXTERNAL GENITALIA.
12. INTRODUCTION
> If female is exposed to testosterone, the
embryo has an ovaries but may develop
MALE ACCESSORY DUCTS and GLANDS, as
well as a MALE REPRODUCTIVE ORGAN
and an empty scrotum.
13. INTRODUCTION
As a result,
PSEUDOHERMAPHRODITES- are formed
who are individuals having accessory
reproductive structures that DO NOT
MATCH their gonads.
True HERMAPHRODITES-are individuals
who possess both ovarian and testicular
tissues.
14. INTRODUCTION
If the normal events fails in the
development of reproductive organs it
may lead to CRYPTOCHIDISM.
This usually occurs in young males and
causes sterility and factor to cancer of
the testes.
Surgery should be performed during
childhood to solve this problem.
15. INTRODUCTION
Abnormal separation of chromosomes
during meiosis can lead to congenital
defects in the reproductive system.
Male who possess extra female sex
chromosome have the normal male
accessory structures, but ATROPHY of
their testes causes them to be sterile.
16. INTRODUCTION
PHIMOSIS –
It is for male which is due to a narrowing
of the foreskin of the male reproductive
structure and misplaced urethral
openings.
17. INTRODUCTION
PUBERTY
Period of life from 10-15 years old.
It is when reproductive organs grow to
their adult size and become functional
under the influence of rising levels of
gonadal hormones. (testosterone for
male; estrogen for female).
18. INTRODUCTION
PUBERTY
In males,
Age 13- increase in the size of
reproductive organs
Followed by the appearance of hair in
the pubic area, axillary and face.
Reproductive organs continue to grow
for 2 years until sexual maturation
marked by the presence of mature
semen in the testes.
19. INTRODUCTION
PUBERTY
In females,
Age 11- budding of their breast.
MENARCHE – is the first menstrual
period which happens 2 years after start
of puberty.
Hormones play an important role in the
regulation of ovulation and fertility.
20. GENDER EXPRESSION
Gender expression describes how
someone prefers to express his or her
gender to the world.
1. CISGENDER
Who is a person identifying himself or
herself with the assigned to them at
birth.
2. TRANSGENDER
Whose gender identify does not match
the sex that they were assigned at birth.
21. GENDER EXPRESSION
3. GENDER FLUID
Referring to a person whose gender
identity is not fixed and /or shifts
depending on the situation.
24. DISEASES associated with the
Reproductive System
INFECTIONS - most common problems
VAGINAL infections are more common
in young and elderly women.
It includes:
ESCHERICHIA COLI
SEXUALLY TRANSMITTED
microorganism:
1. syphilis
2. gonorrhea
25. DISEASES associated with the
Reproductive System
SEXUALLY TRANSMITTED
microorganism:
3. herpes virus
4. yeast (fungus)
26. DISEASES associated with the
Reproductive System
Vaginal infections that are left untreated
may spread throughout and may cause
PELVIC INFLAMMATORY disease and
STERILITY.
Problems that involve painful or
abnormal menses may also be due to
infection or hormone imbalance.
27. DISEASES associated with the
Reproductive System
In males:
Most common inflammatory conditions:
prostatitis
Urethritis
epididymitis
28. DISEASES associated with the
Reproductive System
In males:
All of which may follow sexual contacts
in which SEXUALLY TRANSMITTED
DISEASE (STD) microorganism are
transmitted.
ORCHIDITIS- inflammation of the testes
Most commonly follows mumps in an
adult male.
Can cause sterility.
29. DISEASES associated with the
Reproductive System
NEOPLASMS
Major threat to reproductive organs
TUMORS of the breast and cervix- most
common reproductive cancers in adult
females.
PROSTATE CANCER- sequel to prostatic
hypertrophy.
Problems in adult males.
30. DISEASES associated with the
Reproductive System
Most women hit their highest point of
reproductive abilities in their late 20s.
A natural decrease in ovarian function
usually follows by reduced estrogen
production.
MENOPAUSE
Ovulation and menses stop entirely,
ending childbearing ability.
No longer experience menstruation.
31. DISEASES associated with the
Reproductive System
The reproductive organs and breast
begin to atrophy or shrink if estrogen is
no longer released from the body.
The vagina becomes dry that causes
intercourse to become painful and
vaginal infections become increasingly
common.
32. DISEASES associated with the
Reproductive System
ESTROGEN DEFICIENCY:
Irritability
Mood changes (depression)
Intense vasodilation of the skin’s blood
vessels which causes uncomfortable
sweat-drenching “hot flashes”
Gradual thinning of the skin
Loss of bone mass
33. DISEASES associated with the
Reproductive System
ESTROGEN DEFICIENCY:
Slowly rising blood cholesterol levels
Some physician prescribed low dose
estrogen-progestin to help women
through the difficult period and to
prevent skeletal and cardiovascular
complications.
34. DISEASES associated with the
Reproductive System
ESTROGEN DEFICIENCY:
Slowly rising blood cholesterol levels
Some physician prescribed low dose
estrogen-progestin to help women
through the difficult period and to
prevent skeletal and cardiovascular
complications.
35. DISEASES associated with the
Reproductive System
There is no counterpart for menopause
in males.
Aging men show a steady decline in
testosterone secretion,
Their reproductive capability seems
unending.
Healthy men are still able to father
offspring well into their 80s and beyond.
36. EROGENOUS ZONES
IT refers to parts of the body that are
primarily receptive and increase
sexual arousal when touched in a
sexual manner.
Common erogenous zone:
Mouth
Breasts
Genitals
Anus
37. EROGENOUS ZONES
It may vary from one person to
another.
Some people may enjoy being
touched in a certain area more than
the other areas.
Other areas:
Neck, thighs, abdomen, and feet
38. HUMAN SEXUAL BEHAVIOR
It is defined as any activity-solitary,
between 2 persons, or in a group-
that induce sexual arousal.
39. HUMAN SEXUAL BEHAVIOR
2 major factors that determine
human sexual behavior:
Inherited sexual response patterns
that have evolved as a means of
ensuring reproduction and that
become part of each individual’s
genetic inheritance.
40. HUMAN SEXUAL BEHAVIOR
2 major factors that determine
human sexual behavior:
The degree of restraint or other types
of influence exerted on the individual
by society in the expression of his
sexuality.
41. TYPES OF BEHAVIOR
1. SOLITARY Behavior
Involving only one individual
Self-gratification means self-
stimulation that leads to sexual
arousal and generally, sexual climax.
Usually, most self-gratification takes
place in private as an end in itself, but
can also be done in a sociosexual
relationship.
42. TYPES OF BEHAVIOR
1. SOLITARY Behavior
Self gratification, generally beginning
at or before puberty, is very common
among young males, but becomes
less frequent or is abandoned when
sociosexual activity is available.
43. TYPES OF BEHAVIOR
1. SOLITARY Behavior
Consequently, self-gratification is
most frequent among the unmarried.
There are more males who perform
acts of self gratification than females.
The frequency greatly varies among
individuals and it usually decreases as
soon as they develop sociosexual
relationships.
44. TYPES OF BEHAVIOR
1. SOLITARY Behavior
Majority of males and females have
fantasies of some sociosexual activity
while they gratify themselves.
The fantasy frequently involves
idealized sexual partners and
activities that the individual has not
experienced and even might avoid the
real life.
45. TYPES OF BEHAVIOR
1. SOLITARY Behavior
Humans are frequently being
exposed to sexual stimuli especially
from advertising and social media.
Some adolescents become aggressive
when they respond to such stimuli.
The rate of teenage pregnancy is
increasing in our time.
46. TYPES OF BEHAVIOR
1. SOLITARY Behavior
The challenge is to develop self-
control in order to balance
suppression and free expression.
Adolescents need to control their
sexual response in order to prevent
premarital sex and acquire STD.
47. TYPES OF BEHAVIOR
2. SOCIOSEXUAL behavior
Involving more than one person.
Divided into heterosexual
behavior(male with female)
Homosexual behavior(male/male;
female/female)
It usually begins in childhood and
may be motivated by curiosity, such
as showing or examining genitalia.
48. TYPES OF BEHAVIOR
2. SOCIOSEXUAL behavior
Physical contact involving necking or
petting is considered as an ingredient
of the learning process and eventually
of courtship and the selection of a
marriage partner.
49. TYPES OF BEHAVIOR
2. SOCIOSEXUAL behavior
Petting differs from hugging, kissing
and generalized caresses of the
clothed body to practice involving
stimulation of the genitals.
Coitus, the insertion of the male
reproductive organ to the female
reproductive organ.
50. TYPES OF BEHAVIOR
2. SOCIOSEXUAL behavior
Different coitus:
Marital coitus
Premarital coitus
Extramarital coitus
A behavior may be interpreted by
society or the individual as erotic
depending on the context in which
the behavior occurs. Like kiss..
51. Physiology of Human Sexual
Response
STAGES/PHASES:
1. Excitement phase
It is caused by increase in pulse and
blood pressure
A sudden rise in blood supply to the
surface of the resulting in increased
skin temp., flushing and swelling of all
distensible body parts.
More rapid breathing, secretion of
genital fluid, vaginal expansion
52. Physiology of Human Sexual
Response
STAGES/PHASES:
2. Plateau phase
It is generally of brief duration.
If stimulation is continued, orgasm
usually occurs.
53. Physiology of Human Sexual
Response
STAGES/PHASES:
3. Sexual climax
It is marked by a feeling of abrupt,
intense pleasure , a rapid increase in
pulse rate and blood pressure and
spasm of the pelvic muscles causing
contractions of the female
reproductive organ and ejaculation by
the male.
54. Physiology of Human Sexual
Response
STAGES/PHASES:
4. Resolution phase
It refers to a normal or subnormal
physiologic state.
Males and females are similar in their
response sequence.
Females are physically capable of
repeated orgasms without the
intervening “rest period” required by
males.
