two types of infertility

Secondary: prior conception w. subsequent inability to conceive again
causes of infertility
male factor
endocrine, anatomic, sexual dysfunction
causes of infertility
female factors
PCOS
cervical issues
Tubule/uterine/peritoneal issues (PID)
non pharmacologic management of Infertility
- diet
a. men and women: protein, fruits, vegetables
b. men: zinc - exercise
a. weight loss/ gain. best weight is a normal BMI or within 15% of IBW - smoking cessation
- d/c meds that are associated with infertility
- assistive reproductive procedures
medications that impair fertility
cause hyperprolactinemia
phenothiazines haloperidol opiates h2 antagonists SSRI's verapamil estrogen metoclopramide
mediations that impair fertility
impaired spermatogenesis
alcohol, caffeine, marijuana, nicoteine allopurinol anabolic steroids codeine spirinolactone sulfasazaline
Predicting ovulation
- Basal Body temperature
2. Ovulation predictor kits
basal body temperature testing
what is it?
how does it work?
counseling?
use a specific basal body temperature thermometer
progesterone causes an increase in basal body temp
04-0.6 degree rise in body temp->ovulation has occurred
counseling: place at bedside at night.
start at least 5 min and prior to rising for activity
chart temp, illness, intercourse, medications, et.
test daily, start day 1 of cycle
ovulation predictor tests
how does it work?
counseling
detects lh IN URINE FOR THE SURGE PRIOR TO OVULATOIN
counseling: start 3-4 days before expected ovulation
check at same time every day until you see a color change on the test
have intercourse 24-48 hours after color change detected
all kits vary in testing method and accuracy so you must counsel patients

Clomiphene Citrate
Class: Selective estrogen receptor modulator
Indication: treatment of ovulatory dysfunction in women desiring pregnancy
Mechanism of Action: Blocks estrogen receptors, makes body think it is in a hypoestrogenic state. in turn increases GNRH production.
Effects of mechanism of Action:
increases FSH, LH, therefore stimulating ovulation
Dosing: 50-150 mg oral daily for five days starting on days 3,4,5 of the cycle. max dose 150mg daily for 5 days. not recommended for more than 6 cycles
Adverse Effects: ovary enlargenement, hot flashes, headache, abdominal distention, abdominal distress, bloating. N&V, breast discomfort, abnormal uterine bleeding, visual disturbances
Absolute Contraindications: thyroid and adrenal dysfunction
Pregnancy: –
Warning/ Precautions:

% chance of pregnancy: 30% chance. 7.98% dance of multiple gestations
Pearls:
- OHSS rare
- 50-150 mg oral daily for five days starting on days 3,4,5 of the cycle. max dose 150mg daily for 5 days. not recommended for more than 6 cycles

Pearls:
Class: aromatase inhibitor
Indication: stimulation in anovulatory females with PCOS
Mechanism of Action: converts androgens into estrogens. Hypoestrogen state causes increase in GNRH. also causes thin cervical mucus
Effects of mechanism of Action: increase in GNRH causes increase in FSH, LH thus leading to ovulation
Dosing: 2.5-7.5 mg oral daily for 5 days starting on days 3,4, and 5 of the cycle
up to 5 treatment cycles, with dose increase with subsequent cycles if poor ovulatory response. MDD 7.5 mg for 5 days
Adverse Effects: Serious: flushing, edema, headache, dizziness, fatigue. night sweats, hypercholesterolemia, weight gain, nausea,
Absolute Contraindications:–

induction of ovulation and pregnancy in alignment-anovulatory infertile patients in whom the cause of infertility is functional and not caused by primary ovarian failure
Mechanism of Action: stimulated ovarian folicular growth in women who do not have primary ovarian failure.
Effects of mechanism of Action: growth and maturation of follicles
Dosing: dose should be individualized based on response to therapy. doses can vary from 37.5-450 IU SQ or IM per day
Adverse Effects: headache, ovarian cysts, abdominal pain, nausea, enlargement of the abdomen, injection site reaction, URTI
