Q

What hormone level should be evaluated on day 3?

What levels (high or low) would this indicate?

A
  • FSH & Estradiol
  • ↑ FSH and ↓ Estradiol = ovarian failure

24
Q

What are normal results of a semen analysis?

Study These Flashcards
A

Count: 20 million/mL +

Motility: >50%

Morphology: WHO criteria: >30% normal

Kruger Strict Criteria: >14% normal

25
4 labs for eval of male partner
* Testosterone * FSH * LH * PRL
26
If semen analysis results are abnormal, when should the patient be re-tested?
4 or more weeks later
27
If semen count is \<5 million / mL, what should be evaluated?
* Endocrine evaluation * Possible karyotype
28
If a male partner has low testosterone, what follow up labs should be ordered next?
Prolactin
29
**What do these lab values indicate in male partner?** * ↓ Testosterone, ↑ FSH, ↑ LH
Primary Hypogonadism
30
**What do these lab values indicate in male partner?** * ↓ Testosterone, ↓ Low FSH, ↓ LH
Secondary Hypogonadism
31
**What do these lab values indicate in male partner?** * Normal Testosterone, ↓ sperm count, ↓ LH
Possible exogenous steroids
32
Evaluation of what 4 things need to be normal to be diagnosed w/ "unexplained infertility?"
* Normal uterine cavity * Bilateral patent tubes * Evidence of ovulation * Normal semen analysis
33
What is the medication tx of choice for women \<36 y/o w/ oligomenorrhea or amenorrhea w/ normal FSH, including PCOS?
Clomiphene citrate (Clomid)
34
5 SE of Clomiphene citrate (Clomid)
* Hot flashes * Emotional lability * Depression * Bloating * Visual changes
35
What medication is recommended for women w/ hx of estrogen dependent tumors. What is the MOA?
**Letrozole** (Femara) * Aromatase inhibitor
36
Ovulation is induction w/ \_\_\_\_\_\_ * Often used in conjunction w/ IUI (Intrauterine insemination) * Human menopausal gonadotropin (hMG) or Recombinant FSH (rFSH)
Gonadotropins
37
What are 3 SE of inducing ovulation w/ Gonadotropins?
* Multiple gestation * Ovarian hyperstimulation syndrome * Incr. risk of ectopic pregnancy
38
A laparoscopy is used for patients w/ endometriosis. * What is used for patients w/ recurrent abortions, repeated implantation failure, or distorted endometrial cavity by submucosal leiomyoma?
Myomectomy
39
With an IUI, cervical mucous is bypassed and therefore not an issue. What antibiotic is given empirically with an IUI?
Doxycycline
40
What are the 5 types of ART? (Assisted Reproductive Technologies)
1. **IUI** (intrauterine insemination) 2. **ICSI** (intracytoplasmic sperm injection) 3. **IVF** (in vitro fertilization) 4. **GIFT** (gamete intrafallopian transfer) 5. **ZIFT** (zygote intrafallopian transfer)
41
Describe IUI and the indication to do this?
Sperm is washed to remove prostaglandins, bacteria, & proteins. Sperm transcervically injected into uterus * _Indication:_ mild-moderate male factor infertility * _Preg rate:_ 10-20% * _Cost:_ $350-500/attempt
42
What method is indicated for severe male factor infertility? * It is used in conjunction w/ what female method? * Preg rate? * Cost?
**_Intracytoplasmic Sperm Injection_** * Used in conjunction w/ IVF * Sperm individually injected into each oocyte _Preg rate:_ 20% _Cost:_ $1500-3000
43
**IVF** * Follicle development is monitored via US and Estradiol levels * When follicles mature, ovulation is triggered * How and when are oocytes retrieved from follicles?
Oocytes are retrieved from follicles **before ovulation** by **US guided transvaginal aspiration of follicular fluid**
44
**IVF** * When are embryos transferred into uterine cavity through the cervix after the retrieval of the occytes?
On day 3-5
45
What hormone is supplemented thru 10 weeks gestation if conception occurs with IVF?
Progesterone
46
What is the preg rate and cost of IVF?
_Rate:_ 20% _Cost:_ 10k-15k (30k/delivery)
47
**Which method?** * Egg and sperm placed in fallopian tube * Fertilization occurs in the body * Requires laparoscopy * Pregnancy rate: 25% * Cost: $15,000-20,000 per attempt
**GIFT:** gamete intrafallopian transfer
48
**Which method?** * Zygote placed into fallopian tube * Fertilization occurs in vitro * ‘Natural’ implantation into uterus * Requires laparoscopy * Pregnancy rate: 30% * Cost: $10,000-20,000 per attempt
**ZIFT:** zygote intrafallopian transfer
49
3 "other options"
* Donor oocytes * Donor sperm * Surrogacy – own egg/sperm implanted into another woman for carrying (State specific and expensive)
50
What is the prognosis of infertility w/ unidentified etiology?
60% achieve pregnancy within 3 yrs in ABSENCE of tx
51
