POLYCYSTIC OVARIAN DISORDER
AND ITS IMPACT ON INFERTILITY
Submitted by

2. INTRODUCTION
Poly cystic ovarian syndrome (PCOS) is a chronic hyper
androgenic state.
Women have two ovaries that produce eggs, as well as the
hormones estrogen and progesterone.
During a woman's menstrual cycle, an egg grows in a sac called a
follicle. This sac is located inside the ovaries.
In most cases, this follicle or sac breaks open and releases an egg.
But if the follicle doesn't break open, the fluid inside the follicle can
form a cyst on the ovary. The syndrome is best described as
"hyperandrogenic anovulation.“

3.  Androgens are typically thought of as hormones made by
males. But all women produce androgens also.
 In fact, women need to produce androgen hormones, since
there is only one enzyme step separating androgen hormones
from the ultimate production of estrogen.
 Women with PCOS having even slightly elevated levels of
androgens.

4. CHARACTERISTICS OF PCOD
Irregular or absent menstrual periods.
Polycystic ovaries detected on ultrasound scan.
High levels of Harmones
Testosterone
Oestrogen
Luteinising hormone
Insulin

5. EPIDEMOLOGY
Prevalence estimates for PCOS, as defined by the NIH/NICHD
criteria, indicate that PCOS is a common endocrinopathy
affecting 4%-8% of woman of reproductive age i.e., 24-28
years. The prevalence of PCOS appears to be higher from 37 to
90% in woman with the menstrual abnormalities and also
increase in the presence of certain diseases.

6. SIGNS AND SYMPTOMS

7. RISK FACTOR
The following steps are involved in risk factors;
•Genetics
•Life style
•Weight
•Prenatal factor
•High blood pressure

8. PATHOPHYSIOLOGY

9. contd…
Follicular arrest:
In PCOS, there is a so-called "follicular arrest"; i.e.,
several follicles develop to a size of 5–7 mm, but not further, it
leads to anovulation and amennorhea.

10. ROLE OF ANTIMULLERIAN HARMONE
AMH blood levels are thought to reflect the size of the remaining
egg supply. Women with many small follicles, such as those with
polycystic ovaries have high AMH hormone values.

11. THE ROLE OF ANDROGENS IN
PCOS
• In PCOS, theca cells have increased activities of 17 -hydroxylase,
17,20 lyase and 3 -hydroxysteroid dehydrogenase compared with
theca cells from normal women.
• The increased enzyme activities account for greater androgen
production due to gonadotropin stimulation in PCOS.
• Apart from this, the excess 5α-reduced androgens in the ovaries are
thought to inhibit the action of aromatase and therefore reduce
estradiol synthesis, which is required for further maturation.

AND INSULIN RESISTANCE

14. DIAGNOSIS
A. STANDED DIAGNOSIS
•Ultrasonography
•Laparoscopic examination
•Blood tests
B. DIFFERENTIAL DIAGNOSIS
Other causes of irregular or absent menstruation and
hirsutism, such as hypothyroidism, 21-hydroxylase deficiency,
Cushing's syndrome

15. CONSEQUENCES OF PCOD
 Subfertility
 Miscarriage
 Cardiovascular diseases
 Type 2 Diabetes Mellitus
 Malignancies
 Psychiatric disorders

16. TREATMENT
PCOS is not curable, but the symptoms are treatable by:
•A healthy lifestyle
•Maintaining a healthy weight
Treatment include
•Non surgical treatment
•Surgical treatment
Ovarian Drilling
.Estrogen and progestin
oral contraceptive (OCP)
therapy
•Anti-androgens
•Antidiabetic drug
•Ovulation inducer
•Gonadotropin therapy

17. SURGICAL TREATMENT
OVARIAN DRILLING

18. COMPLICATIONS

19. PCOS IMPACT ON FEMALE INFERTILITY
 Infertility is defined as the absence of pregnency following 12
months unprotected intercourse. Infertility may be caused by
ovulatory dysfunction, blocked fallopian tube male factor
infertility or unexplained causes.
 The infertility rate with polycystic ovaries is very high. these
women usually will have difficulty getting pregnant - and
usually require treatment to improve chances for pregnancy.
 Some women with polycystic ovary syndrome will ovulate
(release a mature egg) occasionally - others do not ever
ovulate. In order to conceive, sperm must find and fertilize a
mature egg - so we need to ovulate.

WOMEN

21. .
CONCLUSION
PCOS is one of the most common disorders affecting women of
reproductive age. For many women with this syndrome,
improving infertility is a primary goal of therapy. It is something
that can be treated by a primary health care physician. However,
maintaining a healthy and active lifestyle may decrease the
chance of developing this condition and its associated infertility.
