Mr. and Mrs. John Takahama, a young couple who had been trying unsuccessfully to have a family for years, underwent a series of tests with a fertility clinic to try to determine the problem. Mr. Takahama was found to have a normal sperm count, and the sperm morphology and motility were normal. (1) If his count had been low, what type of information should be collected to determine the cause of
the low count? Mrs. Takahama's history sheet revealed that she had two episodes of PID during her early 20s, and the time span between successive menses ranged from 21 to 30 days. She claimed that her family was "badgering" her about not giving them grandchildren and that she was frequently despondent. A battery of hormonal tests was ordered, and Mrs. Takahama was asked to perform a cervical mucus test and daily basal temperature recordings. Additionally, gas was blown through her uterine tubes to determine their patency. Her tubes proved to be closed and she was determined to be anovulatory. (2) What do you suggest might have caused the closing of her tubes? Which of the tests done or ordered would have revealed her anovulatory condition? What will be an ideal response?
C) upper respiratory tract.
