EXAM PART A: SECTION 2 (15 minutes; 5 questions; 10 marks)
For the data interpretation questions you may be provided with a figure, table or scenario in
which you are expected to answer either a multiple choice or short answer question. Each of
the 5 data interpretation questions will require you to answer two questions. We have
allowed 3 minutes per question (5 questions and a total of 10 marks).

Question 1. The figure below shows the AMH concentration (pmol/l) in seminal plasma and
sperm count (x 106/ml) of 47 adult oligospermic and normospermic men between the ages
of 26 to 44 years old attending an ART clinic.



I. From the figure above how many normospermic men have an AMH concentration above
200 pmol/l?
a) 10 men
b) 7 men
c) 6 men
d) 5 men
e) 3 men

II. Based on these data, state below, in one to two sentences, your prediction of how AMH
concentration may relate to Sertoli cell function in normospermic men.

…..followed by 4 other Data interpretation questions.

of an embryo, focussing on the hormonal and anatomical changes that
accompany this transition.

Question 2. Identify which steps involved in spermatogenesis many change in length
between humans and ruminants and give 3 examples of how dietary and
environmental factors can impact this process.

Question 3. Outline at least 5 different diagnostic measures used to identify disorders of
