The document discusses female sexuality and psychosexual dysfunction. It provides information on: 1. The sexual response cycle of women, which consists of 5 phases - desire, arousal, plateau, orgasm, and resolution. 2. Biological and psychosocial factors that influence female sexuality, such as hormones, brain regions, experiences, and relationships. 3. Common forms of female sexual dysfunction according to the 1999 consensus classification system, including disorders of desire, arousal, orgasm, and pain. 4. Factors that can cause sexual dysfunction, including medical issues, medications, psychological factors, and relationship issues.

2. Sexuality is a multi-
dimensional concept with
ethical, psychological,
biological and cultural
dimensions.
Sexuality reflects human
character and the way in
which people interact.

3. Sexuality is the lifelong process of
acquiring information and
developing values about one’s
identity, relationships and intimacy.
It includes learning sexual
development, reproductive health,
interpersonal relationships, affection,
body image, and gender roles.

4. genotype
 The main organ that affects male and female
sexual response is the BRAIN.

6. The perception of sexuality is
different for each individual.
Is unique.
The main factors affecting this individuality is
how we spend our adolescence and form
our relationship with the opposite sex.

7. Activated Areas During “Sexual Arousal”
Medial insula
Anterior cingulate cortex
Hippocampus
Striatum
Nucleus accumbens
Hypothalamus
Concentration of dopamine is high in all these areas.

8. Inactivated Areas During “Sexual Arousal”
Amygdala
Frontal cortex
Prefrontal cortex
Temporal pole
Prefrontal cortex is responsible for control mechanism.
Amygdala acts like our emotional memory. Our fears, emotional
moments, events that cause our worry are all evaluated and
stored.

9. Sexually Sensitive Areas
Clitoris
Vagina
Nipples (areola)
Breasts
Labium

10. Sexual Response Cycle of the Woman
 Sexual response cycle of woman consists of 5 phases:
1. Sexual desire phase: Can last for days. Fantasies, dreams about
the sexual object.
2. Arousal phase: Can last from 1-2 minutes to hours.
3. Plato phase: Between 30 seconds to 3 minutes.
4. Orgasm phase: 3-15 seconds
5. Relaxation phase: 10-15 minutes
 In this cycle, there are two basic physiologic processes:
Vasocongestion
Neuromuscular tension– Myotonia
 Vasocongestion takes place in lower and upper genital organs and
breasts, while myotonia takes place in the whole body.

11. Sexual Desire Phase
Motivation to be sexual
Subjectivity (Experience)
Adequate neuroendocrine function
Sexual orientation
Choice
Psychological status
Environmental factors

12. Arousal Phase
 Can last from 1-2 minutes to hours. As a result of parasympathetic
stimulation.
Changes in organs that take place during arousal phase:
 Nipples: Harden. Length can go up to 1cm. In addition, breast volume
increases due to congestion.
 Clitoris: Length of clitoris increase with venous congestion.
 Labium majus: Labium majus moves upward and opens outward with
erection.
 Labium minus: Increase in size 2-3 times both in nullipara and
multipara. Finally, vagina goes out of vault, passes labium majus by
1cm and becomes visible. In nullipara, its color is bright pink, while its
color is dark red in multipara.

13. Vagina:
 When there is an effective sexual stimulation, there is a light colored
vaginal secretion 10-20 seconds after the initiation of the stimulation.
 The stimulation can by physical or psychological. Secretion is in
transuda form. When venous plexus that surrounds vagina fills up
with venous congestion and dilated, capillary permeability increases.
Then, droplets are formed in vagina and vaginal secretion is released.
 Secretion has two purposes:
1. Providing vaginal lubrication
2. Neutralizing vaginal acidity.
 Another important change is the increase of length up to 3 cm in
vagina.

14. Plato Phase
 Lasts around 30 seconds to 30 minutes. In 75% of women, there will
be red spots, known as sexual flash, on the breasts and the skin. In
reality, these spots start in the late section of the arousal phase and
continue in the plate phase.
 It is argued that the red areas are correlated to the intensity of the
sexual arousal.
 Breasts are tense and increase in size.
 Clitoris becomes erect and only mechanical stimulus can be enough to
reach orgasm.
 Uterus re-locates in this phase. It is lengthened to the vagina.
 Near the end of this phase, uterus starts to contract.

15. Orgasm Phase
 Orgasm can be described as the conclusion of the
vasocongestion, release of the collected blood and following
stage of myotonia.
 It is the shortest phase of all phases. It can only be reached
when there is maximum sexual tension.
 Uncontrolled muscle contractions happen every 0.8 seconds.
3-15 contractions can happen. During this phase, uterus also
contracts.

16. Relaxation Phase
Last phase of the sexual response. It is the phase
with the most varying length.
If orgasm is reached, it can last up to 15 minutes. If
orgasm is not reached, it can last up to 1 day.
Clitoris can turn into normal shape in 10-15
seconds. It will take 15 minutes to turn back to
totally normal function. If orgasm is not reached,
this period can go up to 6 hours.

17. Sexual Response

1. Sexual desire phase: Can last for
days. Fantasies, dreams about the
sexual object.
2. Arousal phase: Can last from 1-2
minutes to hours.
3. Plato phase: Between 30 seconds to
3 minutes.
4. Orgaxm phase: 3-15 seconds.
5. Relaxationp phase: 10-15 minutes.

19. Hormones that Influence Female Sexuailty
1. Estrogen
 Sexual Identity: Secondary sexual characteristics
 Functional Influence:
a. Sexual desire: indirect influence (direct
influence??)
b. Arousal: Vasocongestion, vasodilation,
lubrication
c. Orgasm: Matures the orgasmic platform.
 Influence on the Relation: Builds up woman’s unique
scent (??)

20. 5. Androgens
 Basic hormones that have central influence and triggers
sexual desire and central arousal.
 Modulate peripheral arousal.
 Influence secretion of NO.
 Increase clitoral arousal.
 Increase “life energy”. Induce self-esteem.
 Influence pheromone (??).

22. Oxytocin Vasopressin
Known as coupling and love hormones
Oxytocin and V1a type vasopressin receptors are located at
dopaminergic areas that are activated during romantic love.
Oxyitocin; anxiolytic. Named as the trust hormone. Increases in
the beginning of romantic love.
Vasopressin increases response to fear and stress. Induces man’s
claiming urge.

26. When we live so synthetically
in the modern world, can
sexuality and love be
manipulated with hormones?
Should we?
Shouldn’t we?

 Female sexual dysfunction can be temporary, episodic or
continuous
 Can resolve by itself or need treatment
 Reasons are evaluated in 2 headings.
I- Psychosocial Factors
 Mental inhibition, education that refused sexuality during
growing-up: pleasure regarded as a sin ethically.
 Past psychosexual trauma.
 Fears: unwanted pregnancy, somebody finding out about the
cohabitation, pain during coitus
 Problems with the partner: Not desiring intimacy with the
partner, relations that are falling apart.

37. Results
 Totally 349 cases were taken into consideration.
 They were 32,59±7.04 old on average and the number
of weekly intercourse were 2,36±1,34 on average.
6.6% (23/349) were single.
 While 39.8% of women used coitus interruptus as a
contraception method,
 21.5% used IUD,
 16.3% preferred condom,
 10% used oral contraceptive,
 5.2% preferred tubal ligation
 7.2% used none of the methods.

38. 24.6% of them were masturbating in different
frequencies, 5% were performing anal sex and
26.1% were performing oral sex.
36.7% were complaining of dyspareunia. Sexual
dysfunction was identified in 24.4% of the
partners.

39. It is interesting that women performing oral sex was an
independent factor which had a positive effect on
arousal (p=0.02; RR=0.54; [95%CI: 0.32-0.909]),
orgasm (p=0.0045; RR=0.48; [95%CI:0.29-0.8]) and
total score (p=0.016; RR=0.505; [95%CI:0.28-0.88]).
Woman performing oral sex, can be a sign of woman
being capable of sexuality (motivated sexually or
having a good sexual drive) and have a healthy
relationship with her partner on a sexual level. So, the
arousal and orgasm scores of women performing oral
sex are affected positively.

40. Number of sexual intercourse showed negative correlation with
age (-0.151; p=0.005) and the number of deliveries (-0.140;
p=0.009). As the number of deliveries increases, the number of
sexual intercourse decreases and the domains of desire, arousal
and satisfaction were influenced negatively.
