Anovulation- the most frequent cause of female infertility. It can be connected with: Irregular menstruation Irregular menstruation Oligomenorrhea Oligomenorrhea Amenorrhea Amenorrhea Regular menstruations can also occur Regular menstruations can also occur
2
Anovulation- the reasons: Hyperprolactinemia Hyperprolactinemia Hypothalamic- pituitary dysfunction Hypothalamic- pituitary dysfunction Ovarian failure Ovarian failure PCO PCO Diagnostic methods: PRL/MCP, FSH, LH, E 2 serum concentrations between 3 - 6 day of cycle.

INFERTILITY DIAGNOSIS INFERTILITY DIAGNOSIS
11
Hysterosalpingography (HSG) Hysterosalpingogram- x-ray imaging of the uterus and fallopian tubes after instillation of a contrast liquid Hysterosalpingogram- x-ray imaging of the uterus and fallopian tubes after instillation of a contrast liquid Routine infertility evaluation (basic test) Routine infertility evaluation (basic test) Assess morphology of endocervical canal, uterine cavity, tubes. Assess morphology of endocervical canal, uterine cavity, tubes. Rule out tubal occlusion, synechiae, uterine anomalies. Rule out tubal occlusion, synechiae, uterine anomalies.
12
Contraindications to HSG: 1. active PID with abdominal tenderness or palpable mass 2. recent uterine/tubal surgery 3. active uterine bleeding 4. pregnancy (schedule exam before ovulation to avoid early pregnancy)
13
Normal hysterosalpingogram. A smooth triangular uterine cavity and spill from the ends of both tubes.
14
HSG showing a normal uterus and blocked tubes No "spill" of dye is seen at the ends of the tubes
15
Hysterosalpingogram showing a uterus with a myoma that is pushing in to the cavity.
16
A hysterosalpingogram indicate intrauterine adhesions (synechia) intrauterine adhesions (synechia)intrauterine adhesions (synechia)
17
Tubal Recannulization and Selective Salpingography
18
Selective hysterosapingography, or proximal tubal cannulization may open the tubes avoiding surgery.
19
LAPAROSCOPY
20
The camera and instruments are inserted into the abdomen or chest through small skin cuts allowing the surgeon to explore the whole cavity without the need of making large standard openings dividing skin and muscle.
21
After the cut is made in the umbilical area a special ( Veress) needle is inserted to start insufflation. A pressure regulator CO2 insufflator is connected to the needle. The pressure obtained should not be beyond 15 mmHg.
22
After satisfactory insuflation the needle is removed and a 10 mm trocar is inserted through the previous umbilical wound.
23
Laparoscopic view of a normal pelvis. Uterus in midline. Tubes and ovaries (white structures) also visible.
24
Contraindications to laparoscopy: Circulatory and respiratory insufficiency Circulatory and respiratory insufficiency Hypovolemic shock Hypovolemic shock Ileus Ileus Peritonitis Peritonitis Abdominal or diaphragmic hernia Abdominal or diaphragmic hernia Tumors in abdominal cavity Tumors in abdominal cavity
25
Pelvic laparoscopy is also not recommended for patients with: – severe obesity – existing severe pelvic adhesions from previous surgeries
26
Pelvic Laparoscopy: Risks Risks for any anesthesia are: Risks for any anesthesia are: reactions to medicationsreactions to medications problems breathingproblems breathing Risks for any surgery are: Risks for any surgery are: bleedingbleeding infectioninfection damage to adjacent organsdamage to adjacent organs
27
HYSTEROSCOPY HYSTEROSCOPY Assess the endocervical canal, uterine cavity and uterine openings of the oviducts. Assess the endocervical canal, uterine cavity and uterine openings of the oviducts. Enables to make the intrauterine operations. Enables to make the intrauterine operations.
28

30
Contraindications to hysteroscopy: Infections of reproductive organs Infections of reproductive organs Massive bleeding from uterus Massive bleeding from uterus Pregnacy Pregnacy Cervical cancer Cervical cancer
31
Hysteroscopy. Risks. Uterine perforation Uterine perforation Bleeding Bleeding Infection Infection Pulmonary embolism (rare) Pulmonary embolism (rare)
32
Polycystic ovarian syndrome (PCOS) occur in 5- 10% of reproductive-aged women PCOS ovulatory dysfunction or absent ovulation infertility infrequent or irregular menstrual cycles infrequent or irregular menstrual cycles absence of ovulation no progesterone production in the second half of the menstrual cycle the risk for an abnormal buildup of the lining of the uterus (endometrial hyperplasia) or cancer.
33
Another feature to PCOS is clinical or laboratory hyperandrogenism increased circulating amounts of or increased responsiveness to "male" hormones like testosterone or DHEAS Symptoms: oily skin or acne and excess hair on the face, between the breasts, or on the lower abdomen.
34
Changes in the ovaries in ultrasound Ultrasound findings: poly (many), cystic (small collections of fluid). The eggs in the ovaries do not develop to maturity many small "follicles" (small fluid-filled sacs containing immature eggs) seen on ultrasound. The ovaries of women PCOS are often enlarged as well.
35
Another common feature of PCOS is increased body weight and trouble in losing weight. Mechanism: insulin resistance (the cells of women with PCOS do not respond as well to their bodies' own insulin) women with PCOS are at higher risk for developing diabetes during pregnancy or later in life.
36
Treatment Strategies The aim: to help regulate menstrual cyclicity and prevent endometrial hyperplasia. Oral contraceptives (birth control pills- BCPs). BCPs also help reduce acne and facial hair in most patients with PCOS. Oral contraceptives (birth control pills- BCPs). BCPs also help reduce acne and facial hair in most patients with PCOS. In women who do not require oral contraception, progesterone given for 10-12 days every 30- 60 days will induce a reliable menses. For women with PCOS who desire pregnancy, ovulation induction (COH) is often necessary. Drugs that increase insulin sensitivity in PCOS- Metformin help induce ovulation help women to lose weight help women to lose weight
37
In women who cannot tolerate oral medications or have failed several different regimens of medication, surgical induction of ovulation can also be attempted (laser or electrosurgical techniques to place small holes in the ovaries in an effort to normalize the hormonal environment and allow ovulation to occur)
