1 Infertility—A Clinical Dilemma…… Infertility—A Clinical Dilemma…… Dr.Kundan V.Ingale. MBBS, DGO, DNB(Mumbai) Obstetrician & Gynecologist Consultant in Assisted Reproduction & Genetics LOKMANYA HOSPITAL, CHINCHWAD LOKMANYA HOSPITAL, PRADHIKARAN

2 Introduction Traditionally, infertility is defined as the inability to conceive for one year. Worldwide, 10 to 14% of couples in the reproductive age group (20-40) face difficulty in conceiving 90% of infertility is treatable with advances in medicines and clinical procedures Line of treatment includes medical and surgical intervention, Assisted Reproduction Techniques (ART) or a combination of these modalities. Infertility is an extraordinarily common medical problem.

3 INCIDENCE Female Factor: - 40-45% Male Factor: -25-40% Both: - 10% Unexplained: - 10%.

4 Causes of Infertility Female  Anovulation (accounts for 25% of infertility)  Tubal factors (accounts for 25% - 40%of infertility)  Uterine & cervical factor (accounts for 10% of infertility)  Immunological cases, age and other factors (accounts for 25% of infertility) Tubal factor is a common cause of infertility in our country. HSG – Septate uterus HSG – Bicornuate uterus

5 Causes of Infertility Male  Low sperm count  Low motility  Poor sperm morphology  Other factors such as  stress  varicocoele  chromosomal abnormality Both female and male factors contribute to infertility.

6 Infertility Rise in infertility : - - increased women employment - Late marriages - Preferring weekend sex - highly stressful job - Onset of childbearing at later age.

7 Male Infertility Volume: 2-5ml pH: 7.2-7.8 Liquefaction time: within 40 mins. Sperm Count: -20-120 million/ml (WHO Criteria) Sperm motility: >50% after ½ hour. Sperm Morphology: >50% normal.

8 Abnormal Semen Parameters. Oligospermia: - sperm count <20 million/ml Mild: -10-20 million/ml Moderate: -5-10million/ml Severe: -<5 million/ml. Azoospermia: - Absence of single sperm in ejaculate. Asthenospermia: -Sperm motility <50% Teratospermia: - <4% normal sperms associated with poor fertility prognosis.

9 POLYCYSTIC OVARIAN SYNDROME Heterogeneous complex condition – Hyperandrogenemia and chronic anovulation. Associated with Hirsuitism, Hyperinsulinemia & insulin resistance. Commonest cause of anovulation. 50% patient of PCOS need assistance in reproduction.

10 Epidemiolgy of PCOS. Affect 5-10%of all reproductive age group women. 50% women attending infertility cilinics. 50% women with recurrent miscarriages. PCO – LEADING CAUSE OF INFERTILITY.

11 Chronic anovulation High LH/Inadequate LH surge LOW FSH Inability of H-P axis to respond to adequate & timely feedback signals Intrinsic follicular weakness / Impaired follicular-Gonadotropin interaction. Persistently Elevated Estrogen Failed local ovarian autocrine / paracrine factor Abnormal Estrogen Clearance / Metabolism Increased Estrogen secretion Gonadal (Ovary& Adrenal) Extragonadal (Adipose tissue)

12 INSULIN RESISTANCE & HYPERINSULINEMIA Causes: -  Peripheral target tissue resistance. Decreased insulin receptor number Decreased insulin binding Post-receptor failure  Decreased hepatic clearance.  Increased pancreatic sensitivity. INSULIN RESISTANCE – OBESE & NON-OBESE WOMEN.

13 PCO – THE SIGN Partial suppressed FSH New Follicular growth Follicular atresia Repeated follicular atresia & anovulation Thickened stroma PCO Hyperplastic theca cells Luteinized due to LH PCO : Sign, not a disease.

14 PCOS- DIAGNOSIS MAJOR  Chronic anovulation  Hyperandrogenemia  Clinical signs of Hyperandrogenemia. MINOR  Insulin resistance  Perimenarchal onset of hisuitism and obesity  Elevated LH and FSH ratio  Intermittent anovulation assoc with Hyperandrogenemia

15 Tubal Factor Fallopian tube blockage: Sites : Cornual end, interstitial, isthmus, ampulla, fimbrial end.

16 FALLOPIAN TUBE BLOCKAGE  Tubo-Cornual region: - Tubal spasm Salphingitis Isthmica nodosa(SIN) Endometriosis Polyps  Isthmus: - Occlusion-Prior sterilization,tubal pregnancy, SIN, T.B. Endometriosis.  Ampulla: - Intraluminal adhesions, Tubal pregnancy  Infundibulum: - Hydrosalphinx, phimosis of distal tubal ostium sec to PID.  Intraperitoneal spread: - Adhesions.

17 DIAGNOSIS  Patency of tube – Laparoscopic chromotubation – Hysterosalphingo graphy – Falloposcopy – Methylene blue test – Gas hydrotubation – Sonosalphingography – Direct cannulation  Functioning of tubal mucosa – Microsphere migration – Descending tests Starch & Gold.

18 MANAGEMENT OF TUBAL BLOCK  Proximal tubal disease: -Tubal cannulation IVF  Mid tubal disease: - Tubal reconstruction Microsurgery/IVF  Fimbrial / distal tubal disease: - Fimbrioplasty  Peritubal disease: -Adhesiolysis/IVF  T-O mass / multiple tubal block: -IVF/ICSI

19 Assisted Reproductive Techniques Intrauterine insemination (IUI) In Vitro Fertilization (IVF) Intracytoplasmic sperm Injection (ICSI) Laser Assisted hatching (LAH) Pre-implantation genetic diagnosis.(PGD) In vitro Maturation Donor oocyte programme.

20 IUI : Stimulation protocols  Natural cycle  Stimulated cycle CC CC+HMG CC+HMG/FSH+hCG FSH/HMG+hCG GnRHa + FSH/HMG + hCG  Follicle monitoring  Timing of IUI Success rate is high if more then one egg is produced.

21 Clomiphene Citrate Occupies the Estrogen receptor Concentration of Estrogen receptor is reduced No Negative feedback HPO axis is blind to Estrogen GnRH secretion activated FSH & LH pulse frequency increased Maturation of follicles

22 Results with Clomiphene Citrate 70% Ovulation rate 40% Pregnancy rate 5% have multiple pregnancy 60% conceive during first three cycles. If there is no pregnancy in 6 cycles, alternative therapy to be chosen.

23 IUI with Gonadotropin treatment Gonadotropins : contain naturally occurring pituitary hormones (FSH & LH) Daily injections: creates higher than normal levels of FSH, simulating the ovaries to produce multiple follicles and multiple eggs. Transvaginal sonography: to check the growing follicles. Subcutaneous self injection into the thigh or abdomen.

24 Gonadotropins : Indications Indications: -Failure to respond to antiestrogen therapy At least 3 cycles of C.C. and no ovulation Dose: 0-200mg/day for 7 days. At least 6 Ovulatory cycles and not conceived. -Side effects to antiestrogen therapy irrespective of ovulation -Two or more miscarriage after C. therapy.

25 Step Up protocols  Ovulation in PCO pts remains a challenge  OHSS, multiple pregnancy & LUF’s are a problem.  Allows right amount of FSH to connect the hormonal imbalance within the PCOS ovary.  Fewer follicles per cycle  Safer successful ovulation induction  OHSS reduced.

26 Step Down Protocols Principle Principle : Activating pre-Ovulatory follicles and limiting the number of growing follicles by hormonal therapy. Advantages Advantages: Reduced risk of OHSS & multiple pregnancy. Disadvantages Disadvantages: Needs tight monitoring. Increased cancellation cycles.

27 Metformin in PCO patients  In cases diagnosed to have insulin resistance.  1500mg/day till pregnancy achieved.  Given for at least 2 mths prior to ovulation induction programme.


29 What is IUI? Direct placement of processed highly motile, concentrated sperm, washed free of seminal plasma and other debris, into the uterus as close to the ovulated oocytes as possible. Reduces distance of travel Artificial insemination.

30 IUI The Goal is to place as many active, well-formed sperms as close to the ovulated eggs as possible, thereby increasing their chances of meeting.

31 Indications for IUI Female factor: Anatomic defects Cervical factors Ovulatory dysfunction Unexplained infertility Minimal endometriosis Antisperm antibodies in cervix Psychological & Psychogenic sexual dysfunction Male Factor: Anatomic defects of the penis Sexual or ejaculatory dysfunction Retrograde ejaculation Impotency Immunological increased viscosity Oligoasthenoteratozoospermia Azoospermia

32 Steps involved in COH & IUI Monitoring of a natural or stimulated cycle: so that the time of ovulation is apparent Preparation of Sperm wash: From either male partner or donor Procedure of Insemination: Sperm sample is then inserted into woman’s uterus via a catheter through the cervix.

33 IUI : Complications Uterine cramping -5% Spotting -1% G I upset -0.5% Infection -0.2% OHSS -1% Multiple gestation Ectopic gestation Artificial Insemination

35 IUI Results 751 cycles in 322 couples TreatmentFecundity/Cycle COH6.3% IUI3.4% COH + IUI19.6% Chaffkin L.M.;Nulsen,J.C.,1991

36 IUI Failures  Poor responders  Hyperstimulation  LUF  Endometrial problems  Insatisfactory semen preparations


38 ICSI Procedure ICSI involves injection of single sperm into the egg

39 Success Rates If 4 good quality embryos are produced following ICSI and the age of the woman is < 37 years, the pregnancy rates are 45% The hallmark to success is good quality embryos

40 Intra Cytoplasmic Sperm Injection (ICSI) The advent of ICSI has revolutionised male factor fertility.  Revolutionary treatment for patients with severe male factor infertility  Fertilisation rate of mature eggs injected with immobilised sperm reached levels comparable to those obtained in conventional IVF  Also used to treat couples experiencing failure or low fertilisation rates under conventional IVF conditions

41 Phases of IVF Cycle One cycle is spread over a period of 25-30 days.  Pituitary suppression (Down regulation) Done with Day 21 Lupride inj followed by stimulation with HMG or r-FSH.  Ovarian stimulation Fixed regimen - Step up and Step Down  Egg retrieval 34-36 hours after ovarian trigger

42 Phases of IVF Cycle One cycle is spread over a period of 25-30 days.  Fertilisation by ICSI  Embryo transfer  Luteal phase and pregnancy

43 Donor Programme Donor sperms : - – azoospermia Donor oocyte : - – Premature ovarian failure – Advanced maternal age with poor ovarian reserve Donor embryo : - – Severe male as well as female factor.

45 Cryopreservation For future fertilisation attempts

46 Laparoscopy Looking inside the abdominal cavity

47 Hysteroscopy Looking inside the uterus

48 Myths about infertility  Timing of intercourse  Frequency of intercourse  Certain coital positions improve chances of conception  Orgasm, libido, stress & tension  IUI improves chances of conception  Drugs to improve sperm count  Cold baths, loose pants  Unexplained infertility
