infertility
Infertility
  • Failure to achieve pregnancy despite one year of regular intercourse in a cohabiting couple.
  • Primary-Infertility in woman with no previous pregnancy.
  • Secondary- Infertility in a woman who has previously been pregnant.
  • Incidence -10-15%
slide3
Mrs Bee is a 32 year old house wife. She has been trying to get pregnant for last one year following removal of IUCD. The IUCD was in place for 2 years and was removed at her request because of her wish to try for another child. She has recently been experiencing heavy periods that was attributed to the coil. Her periods are erratic.

Her first child was a normal delivery following which she used OCP. Her second child was delivered by C/S for fetal distress. Postnatally she had an episode of endometritis that required a course of antibiotics. She had coil inserted 3 months post delivery.

Her partner is not the father of her two children. He has no children. There are no reported problems with the intercourse.

slide4
What is the diagnosis?

Secondary infertility

What features in her history are significant & what additional questions would you ask?

Age, BMI

Periods- length,duration, regular/irregular , menorrhagia Dysmenorrhea, dyspreunia, Pelvic pain

Previous contraceptive

Previous pregnancy, previous H/O infertility

Pelvic infection

surgical history- ruptured appendix, tubal surgery

Frequency of intercourse

Occupation

slide5
What features in his history are significant & what additional questions would you ask?

?Age

Occupation

Previously fathered a child

Life style- smoking, alcohol, ? Tight Clothes

Medical History- mumps orchitis, undescended testis, varicocele, testicular surgery.

Any problems with intercourse ( ? Cyclist)

Frequency of intercourse

slide6
What investigations will you carry out? Indicate it’s significance.

Hormone profile: LH/FSH (D2-3)

SHBG/ Testosterone/E2

Prolactin

D21 Progesterone (>30mmol/l)

Tubal patency test: HSG

HyCosy

Lap+ dye insufflation

Pelvic USS: PCO, Hydrosalphinx,Ovarian cyst(endometriotic)

Semen Analysis: volume - 2-5ml

(repeat sample count- >10 million/ml

if abnormal result) abnormal forms 85%

motility > 50%

slide7
What are causes of infertility? What is the likely cause in this case?

Anovulation

*Hypothalamus- Stress, Low BMI

* Pitutary- Hyperprolactinemia

*Ovarian- PCOS, Premature menopause, ovarian dysgenesis

* Endocrine- Cushing & CAH

Hypo/hyperthyroidism

Poorly controlled DM

Tubal factor

* Salphingitis- Chlamydia,gonorrhea, TB, pelvic peritonitis

* Peritubal adhesion/scarring- Endometriosis

Uterine- Fibroid, Asherman’s syndrome

Male factor - Hypo gonadotrophism, infection, surgery

slide8
What are the management options for infertility? What may be an option in this case.

- Life style- weight, Stop smoking/alcohol,loose underwear

- Ovulation induction

*Clomiphene- D2-6, dose 50-150mg daily PO

Side effects-Multiple pregnancy(10%), Ovarian hyper stimulation syndrome

*Gonadotrophins - LH/FSH, FSH IM injection prep

Expensive; OHSS; multiple pregnancy(25%)

*GnRH pump- S/C or IV pulsed release 10-25mcg every 90min; Expensive; multiple pregnancy less common

- Tubal surgery

- IVF/ ICSI

- Treatment for Male factor?

contraception
Contraception
  • Pearl index- Failure rate of contraceptive method i.e no of unwanted pregnancies which occur in 100 women using that method for a year
  • Methods not requiring medical consultation:

* Male - Coitus interrupts (PI=15-20)

-Sheath (PI 4-10) …..reduces risk of STI

* Female - Rhythm method (PI=12-20)

( safe period, basal body temp, consistency of cx mucus, LH surge ovulation kit)

slide10
Methods requiring medical supervision:

* Oral- OCP, POP

* Parenteral- Injection, Implant

* Intrauterine device- Cu Coil, Mirena

* Other devices- Occlusive diaphragm & caps

Permanent methods

*Tubal occlusion

*Vasectomy

combined hormonal prep
Combined hormonal prep.

side effects disadvantages of parenteral preparation
Side effects & Disadvantages of Parenteral preparation

- Menstural irreularities/ amenorrhea

- Delayed return to fertility

- Decrease bone mineral density (avoid in women > 45yrs)

- Progesterone side effect

  • Displacement of coil
  • Expulsion- 3%
  • Vasovagal attack
  • Ectopic pregnancy
infection iucd
Infection & IUCD
  • Increased risk of infection within 20 day of insertion
  • Screen for STI if: < 25yr

> 25yr if -had multiple partner

-new partner

-their partner had multiple partner

emergency contraception
Emergency Contraception
  • Levonorgestral 1.5 mg (levonelle)

*With in 72 hrs ( effective upto 120hr but decreased efficacy)

*Counseling- Next period early/late

- Use barrier method until next period

- Return if sudden abd pain- ectopic

- Return in 3-4 wks if period heavy/light/absent

  • Cu IUCD with in 5 days
female sterilization
Female Sterilization
  • Laparoscopy- rings, clip,diathermy
  • mini laparotomy/ at C/S- Tubal ligation ± diathermy
  • Stable relationship
  • Family complete
  • Permanent
  • Failure rate- 1/200
  • Increased ectopic
  • Does not alter period/ age at menopause
  • Complication of surgery/ GA
  • Success rate with reversal - 50-70%
male sterilization
Male sterilization
  • Vasectomy
  • Simple & safer than female steri.
  • Done under local anaesthetic

  • Success of reversal 50%
slide29
What is the most appropriate options for contraception & Why ?

1. A 37 year old woman who smokes and has a BMI 35 wishing contraception

(VTE risk->35, smoker, BMI>35)

2. A 30 year old epileptic with difficult control of fit

(OCP interaction with hepatic enzyme inducer)

3. A 25 year old air stewardess working mainly on long haul flights

(VTE risk)

4. A 17 year old fit and well requesting contraception

( STI risk)

5. A 28 year old with HIV

( STI risk anti retroviral drug interaction with OCP)

slide30
6. 36 year old with 4 children BMI 38, wishing a permanent method of contraception

( Wt-risk of surgery)

7. A 40 year old embarking on a new relationship requiring contraception

( Not long acting preparation)

8. A 30 year old wishing long term contraception and multiple partners

( Risk of STI)

9. 20 yr old patient unprotected intercourse 4 days previously D16

( Emergency contraception, levonelle less effective)

10. Breakthrough bleeding on the COCP

(biphasic/triphasic pill)

11. Drug interaction with OCP

Hepatic enzyme inducer- phenytoin,phenobarbital,rifampicin, griseofulvin

Antiretrviral drugs

Antibiotic- ampicillin, doxycycline ( impair the bacterial flora that help reabsorption of estrogen from large bowel)
