  3. If semen analysis is normal and ovulation is confirmed, then work up for fallopian tube abnormalities
225
Q

Normal semen analysis

A
  • Volume: > 2m:
  • pH 7.2 - 7.8
  • sperm density: > 20 million/mL
  • sperm motility: 50%
  • sperm morphology: > 50% normal
226
Q

If patient submitted 2 abnormal semen samples 4-6 weeks apart, next step?

A

Pursue fertility options such as:

  • intrauterine insemination
  • intracytoplasmic sperm injection
  • IVF
227
Q

Anovulation workup

A
  • Basal body temperature: no midcycle temp elevation
  • Low progesterone
  • Proliferative histology on endometrial bx
228
Q

Common causes of anovulation

A
  • Hypothyroidism

- Hyperprolactinemia

229
Q

Ovulation induction

A
  • Clomiphene citrate
  • Human menopausal gonadotropin (used if clomiphene fails)
  • Monitor for ovarian hyperstimulation leads to increased ovarian size
230
Q

Diagnosing tubal abnormalities

A
  1. Check for chlamydia IgG antibody test to r/o infection induced tubal adhesions
  2. Hysterosalpingogram ( HSG ) to check for normal anatomy
  3. Laparoscopy: if HSG is abnormal to visualize oviducts and attempt tuboplasty
231
Q

Unexplained infertility

A
  • normal semen analysis, ovulation confirmed, and no tubal abnormalities
  • no treatment indicated
  • 60% patients achieve spontaneous pregnancy within 3 years
232
Q

iVF

A
  1. Eggs aspirated from ovarian follicles using U/S guided transvaginal approach
  2. Fertilied w/ sperm in lab, resulting in embryos
  3. Multiple embryos transferred into uterine cavity
233
Q

Gestational Trophoblastic Disease

A
  • abnormal proliferation of placental tissue involving both cytotrophoblast and/or syncytiotrophoblast
234
Q

GTN

A
  • most common in Taiwan and Phillipines

- risk factors include age extremes (< 20 years old and > 35 yerars old) and folate deficiency

235
Q

GTN: Presentation

A
  • Bleeding < 16 weeks gestation
  • Passage of vesicles from vagina
  • may see HTN, hyperthyroidism, and hyperemesis gravidarum and no fetal heart tones appreciated
236
Q

GTN: Signs

A
  • Fundus larger than dates
  • Absence of fetal heart tones
  • Bilateral cystic enlargement of ovaries (theca-lutein cysts)
237
Q

Most common site of distant metastasis for GTN

A

lungs

238
Q

Complete molar pregnancy

A
  • empty egg
  • 46, XX
  • fetus absent
  • 20% are malignant
  • treat w. no chemotherapy but serial B-hCG until negative
  • F/u for 1 year on OCP
239
Q

Partial molar pregnancy

A
  • Normal Egg
  • 69, XXY (triploidy)
  • fetus nonviable
  • 10% are malignant
  • treat w/ no chemotherapy but serial B-hCG until negative
  • F/u for 1 year on OCP
240
Q

32 y.o Filipino woman is 15 weeks’ pregnant by dates. She presents w/ painless vaginal bleeding associated w/ severe nausea and vomiting. Her uterus extends to umbilicus but no fetal heart tones appreciated. Her blood pressure is 162/98 mm Hg. Dipstick urine shows 2+ proteinurisa. Which of the following is likely diagnosis?

A

Molar pregnancy

241
Q

GTN: Diagnostic Testing

A

U/S

  • reveals homogenous intrauterine echos w/o a gestational sac or fetal parts
  • “snowstorm” ultrasound
242
Q

GTN: Management

A
  • Baseline qualitative B-hCG titer
  • Chest X-ray (r/o lung metastasis)
  • Suction dilation and curretage (D&C)
  • Place patient on effective contraception to ensure no confusion w/ recurrent disease or pregnancy
