Learning ObjectivesLearning Objectives
Following the presentation “Babies With Test Tube” participants should be able to:
– Understand initial infertility evaluation. – Clarify evaluation and therapy with:
• Normal History and Physical
• Irregular Menses
• Dysmenorrhea
EvaluationEvaluation
• Months– 6 Months– 12 Months– 36 Months
• Available Resources
• Age– 28– 38– 45
Off-Label DiscussionOff-Label Discussion
• Clomiphene Citrate
• Oral hypoglycemics
• Estradiol
• Progestins
GoalsGoals
• One healthy baby• Twins can be a major complication.• Triplets are often a major complication.
EvaluationEvaluation
• History• Physical• General Lab
– Pregnancy Test, Pap Smear, GC and Chlamydia– CBC, TSH, prolactin, rubella, vitamin D*
• Fertility Lab– Semen Analysis– Luteal Progesterone
* Vitamin D deficiency is associated with pre-eclampsia and C-section for small pelvis
EvaluationEvaluation
• Day 3 FSH and E2 if age ≥38 (≥35)
• HIV, RPR, fasting glucose, Type and Rh,free testosterone, testosterone, DHEAS, 17 OHP (follicular)
• Sonogram
• Sonohysterogram
• Hysterosalpingogram (HSG)
• Hysteroscopy
• Diagnostic Laparoscopy
GeneralGeneral
• Prenatal Vitamins• Pregnancy test before any medication
– Clomiphene Class X• Includes neural tube defects.
Day 18 to 30 after ovulationUse folic acid up to 5 mg dailyStart 96 hours to 6 months before pregnant
– Femara Class X

BasicsBasics
• Sperm
• An adequate number of spermatozoa must be deposited at or near the cervix at or near the time of ovulation, ascend into the fallopian tubes, and fertilize an ovum.
BasicsBasics
• Ovary
• A mature ovum must be released from the ovaries, ideally on a regular, predictable, cyclic basis.
BasicsBasics
• Cervix
• The cervix must capture, nurture, and release spermatozoa into the uterus that then travel into the fallopian tubes.
BasicsBasics
• Peritoneum
• The fallopian tubes must have a functional anatomic relationship with the adjacent ovaries to facilitate travel and capture.
BasicsBasics
• Tubes
• The fallopian tubes must be patent and also capable of timely transport of an embryo to the uterine cavity.
BasicsBasics
• Uterus
• The uterus must be receptive to embryo implantation and capable of supporting subsequent normal growth and development.
OvulationOvulation
• An LH (luteinizing hormone) surge begins 24 to 36 hours prior to ovulation and peaks 12 to 24 hours before ovulation.
• Follicular rupture = It is the ovary’s job to make a cyst and rupture it.
• Progesterone is increasingly produced after the LH surge• Secretory changes occur in the endometrium due to
progesterone.
OvulationOvulation
• Pregnancy is absolute proof of ovulation.
• Serum progesterones are 99%+– 8 days after a positive ovulation test– 7 days after ovulation on a monitor– Day 21 and 24 if ovulation day is uncertain.
Ovulation DisordersOvulation Disorders
• PCOS
• Hypothyroidism
• Hyperprolactinemia
• Weight Loss / Weight Gain
PCOSPCOS• Diagnosis is more clinical than lab.
– Androgenism (hirsute, acne, central obesity)
– Oligo-anovulatory
– PCOM – polycystic morphology• > 12 follicles at 2 - 9 mm in at least 1 ovary
• Volume > 10cc
• Does not apply if on BCPs
• If a follicle is >10mm, repeat scan next cycle
– Elevated androgens• Androgens decrease with age
– Decreased HDL and SHBG
PCOSPCOS
• Treatment– Weight loss and exercise– Clomid (clomiphene citrate) (3 months)– Femara (aromatase inhibitor) (3 months)– Metformin (6 months)
• Note that the combination of Metformin and Clomid are more productive at months 4-6 compared with months 1-3 .
– Gonadotropins
PCOSPCOS
• Weight loss– Poor results if BMI > 50– Requires a dedicated program of diet and
exercise– Use dieticians who work with diabetics– Liposuction of cutaneous fat is not the same
as loss of visceral weight
Letrozole and ClomipheneLetrozole and ClomipheneBirth DefectsBirth Defects
• There is no increase in birth defects for letrozole or clomiphene if used when not pregnant.
• Letrozole associated with fewer birth defects than clomiphene but this is not statistically significant.

ClomipheneClomiphene
• Four ovarian responses to clomiphene– Ovulatory response– Anovulatory response– Ovulatory dysfunction– Luteinized unruptured follicle (LUF)
• Ultrasound characteristics of ovulation
Ovulation MonitoringOvulation Monitoring
• Basal body temperature charting (BBTC)• Mid luteal phase serum progesterone• Urine LH hormone detection (ovulation kits)• Serial ultrasounds for follicular growth and
collapse.
Sonographic CollapseSonographic Collapse
• Collapse at 24 mm maximum or 21 mm mean with no stimulation –2 to 3 mm larger with clomiphene
• Scan 1 to 2 days after collapse
Luteinized Unruptured FollicleLuteinized Unruptured Follicle
• No Collapse
• May respond to 10,000 to 20,000 IU HCG
Clomiphene CitrateClomiphene Citratefor PCOSfor PCOS
• Ovulatory rate - 80%• Pregnancy rate - 40%• Multiple rate
– Twins - 5%
– Triplets - < 1%
• 80% of pregnancies occur in 4 cycles – 85% at 3 months if IUI

These are not today’s subject since few of my patients can afford them.
