THE SEXUAL SELF
At the end of this lesson, the students

should be able to:
❖ Discuss the development aspect of the reproductive system

❖ Describe the erogenous zone
❖ Explain human sexual behaviour
❖ Characterized the diversity of sexual behaviour
❖ Describe sexually transmitted disease and;
❖ Differentiate natural and artificial methods of contraception
 Ithas been believed that sex chromosomes of humans define the sex
(Male or Female) and their secondary sexual characteristics. From our
childhood, we are controlled by our genetic makeup. It influences the
way we treat ourselves an others.
 However, there are individuals who do not accept their innate sexual
characteristics and they tend to change their sexual organs through
medications and surgery.
 Aside from our genes, our society or the external environment helps
shape our selves.
 The formation of male and female structures depends on the presence
of testosterone.
 Once formed, the embryonic testes release testosterone.
 In the case of the female embryo that forms ovaries, it will cause the
development of the female ducts and external genetalia since
testosterone hormone is not produced.
 Any intervention, with the normal pattern of sex hormone production
in the embryo results in strange abnormalities.
 A criticalevent for the development of the productive takes place about
one month before birth wherein the male testes formed in the
abdominal cavity at approximately the same location as the female
ovaries, descend to enter the scrotum.
 Abnormal separation can lead to congenital defects of the reproductive
system.
 Puberty is the period of life, generally between the ages of 10-15 years
old, when the reproductive organs grow to their adult size and become
functional under the influence of the rising levels of gonadal hormones
(Testosterone in male and Estrogen in female).
 Afterthis time, reproductive capabilities continues until old age in
male and menopause in females.
 The changes that occurs during puberty is similar in sequence in all
individuals but the age which they occur differ among individuals.
 In males, as they reach the age of 13, puberty is characterized by the
increase in the size of he reproductive organs followed by the
appearance of their hair in their pubic area, axillary, and face.
 In females, the budding of their breasts usually occurring in the age of
11that signals their puberty stage. Menarche is the first menstrual
periods of females which happens two years after the start of the
puberty stage.
 Hormones plan an important role in the regulation of ovulation and
fertility of females.
Disease associated with the
Reproductive System
 Infectionsare the most common problem associated with the

reproductive system in adults.
 Vaginal infection are most common in young and elderly women and
of those whose resistance in disease is low.
 The usual infections is the sexually transmitted infection are syphilis \,
ghnorrhea, and herpes virus.
 There is no counterpart menopause for men. Aging men shows a steady
decline of testosterone secretion.
 In female there is a counterpart after menopausal.
 Some physicians prescribe low-dose estrogen progestin preparations to
help women through this usually difficult period and to prevent skeletal
and cardio vascular coplications.
Erogenous Zone
 Refersto part of the body that are primarily receptive and increase
sexual arousal when touched in sexual manner.
 Othercommon area of the body that can aroused easily may include
the neck, thighs, abdomen, and feet.
The human Sexual Behaviour
 Anactivity-solitary between two persons or in a group that includes

sexual arousal.
 There are two major factors that determine human sexual behaviour
namely the inherited sexual response patterns that have evolved as a
means of ensuring reproduction and that became a part of each
individual genetic inheritance, and the degree of restraint or other type
of influence exerted on the individual by the society in the expression
of his sexuality.
Types of Behaviour
 -usually classified according to the gender and number of participants.

1. Solitary behaviour- involving only one individual
2. Socio sexual behaviour – involving more than one person
a).Heterosexual behaviour – (Male and female)
b). Homosexual behaviour – (male or male or female with female)
If three or more individuals are involved it is possible to have
heterosexual and homosexual activity simultaneously.
Sexual Behaviour
Maybe classified as physiological, psychological and social in origin.

Physiological problem is the least among all. Only a small number of
people suffer from diseases that are due to abnormal development or the
genetalia or that part of the neurophysiology controlling response.
Fortunately, the majority of the physiological sexual problem can be
resolved through medication or surgery while problems of the nervous
system that can affect sexual response are more difficult to treat
Psychological problems comprise by far the largest category. They are
usually caused by social induced inhibitions, maldaptive attitudes,
ignorance, and sexual myth by society. Premature emission of the semen
is the most common problem, especially for the young males. Sometimes
this is not the consequence of any psychological problem but rather the
natural result of the tension in a male who has been sexually deprived.
Ejaculatory impotence, which results from the inability to ejaculate in
coitus, is uncommon and is usually of psychogenic origin. It appears to
be associated with ideas of contamination or with memories of traumatic
experiences.
Vaginismus is a strong spasm of the pelvic musculature constricting the
female reproductive organ so that penetration is painful or impossible.
Sexually transmitted Disease
Are infections transmitted from an infected person through sexual

contact.
STDs are significant global health priorities because of their

overwhelming impact on women and infants and their inter-relationships
with HIV and AIDS.
Sexually transmitted Disease
STDs can lead to long term health problems usually in women and
infants. Among the health complications that arise from the STDs are
pelvic inflammatory disease , infertility, tubal or ectopic pregnancy and
cervical cancer.
One of the leading STDs worldwide is AIDS.
