    Incorrect

    • What is the lower reference limit for sperm concentration according to the WHO criteria?

      Your Answer: 1.5 million spermatozoa per ml

      Correct Answer: 15 million spermatozoa per ml

      Explanation:

      WHO guidelines
      Semen volume: Greater than or equal to 1.5 ml
      pH: Greater than or equal to 7.2
      Sperm concentration: Greater than or equal to 15 million spermatozoa per ml
      Total sperm number: 39 million spermatozoa per ejaculate or more
      Total motility (% of progressive motility and nonprogressive motility): 40% or more motile or 32% or more with progressive motility
      Vitality: 58% or more live spermatozoa
      Sperm morphology (percentage of normal forms): 4% or more

    Correct

    • A 29 year old patient has a transvaginal ultrasound scan that shows a mass in the left ovary. It is anechoic, thin walled, is without internal structures and measures 36mm in diameter. What is the likely diagnosis?

      Your Answer: Functional cyst

      Explanation:

      Features of functional ovarian cysts on ultrasound are: Thin walled and unilocular Must be >3cm diameter (if <3cm described as follicle) Anechoic (absence of internal echoes) No colour flow No solid components

    Correct

    • A patient who has been seen in fertility clinic phones regarding the timing of her progesterone blood test. She has regular 35 day menstrual cycles. When testing for ovulation what day of her cycle should she have the test on?

      Your Answer: 28

      Explanation:

      When testing for ovulation the best test is to check the progesterone level. The mid luteal progesterone levels should be checked 7 days prior to the next period. That will be the 28th day in a 35 day cycle.

    Incorrect

    • You are called to see a 24 year old patient who is currently in labour but is failing to progress. A fetal blood sample is sent for analysis. pH is 7.22. Which of the following is the appropriate course of action?

      Your Answer: Repeat in 30 minutes if CTG remains abnormal

      Correct Answer: Consider delivery

      Explanation:

      A normal pH value is above 7.25. A pH below 7.20 is confirmation of fetal compromise. Values between 7.20 and 7.25 are ‘borderline’.

      The base deficit can also be useful in interpretation of the fetal scalp pH. A base excess of more than -10 demonstrates a significant metabolic acidosis, with increasing risk of fetal neurological injury beyond this level. Delivery should be considered.
