Protocol - Causes and Treatments of Known Infertility - Male
The interviewer asks the participant questions about whether the participant or partner has needed medical assistance with having a baby, the type of assistance, and the type of infertility problems.
Questions 1-3 are asked of both males and females.
The National Survey of Family Growth (NSFG) provides a card of response categories to the respondent. For example, in question 2, an investigator would provide the respondent with a card listing the categories "advice, infertility testing, drugs to improve ovulation," "surgery to correct blocked tubes," "artificial insemination," "treatment for varicocele," and "other types of medical help." The Expert Review Panel recommends that additional categories be added to question 2 for “donor sperm,” “in-vitro fertilization,” “intracytoplasmic sperm injection,” “testicular sperm retrieval,” and “vasectomy reversal.” For question 3, they recommend revising the first category to “sperm problems” and adding additional categories for “hormone deficiency” and “genetic infertility (e.g., Klinefelter syndrome).” A card was also provided in question 3.
The male NSFG questions (questions 1-3) have been modified to indicate partner instead of wife.
Below is a definition from the Mayo Clinic website that researchers may find helpful in using the toolkit:
- A varicocele (VAR-ih-koe-seel) is an enlargement of the veins within the scrotum, the loose bag of skin that holds your testicles. A varicocele is similar to a varicose vein that can occur in your leg. Varicoceles are a common cause of low sperm production and decreased sperm quality, although not all varicoceles affect sperm production. Varicoceles also can cause testicles to shrink. (Mayo Clinic. http://www.mayoclinic.com/health/Varicocele/DS00618. Accessed February 15, 2010.)
The PhenX Working Group recommends this measure should be preceded by "Difficulty Getting Pregnant" for a more complete assessment of infertility.

Protocol Name from Source:
National Survey of Family Growth (NSFG)
Personnel and Training Required
The interviewer must be trained to conduct personal interviews with individuals from the general population. The interviewer must be trained and found to be competent (i.e., tested by an expert) at the completion of personal interviews. The interviewer should be trained to prompt participants further if a "don’t know" response is provided.
If a computer-assisted instrument is used, computer software may be necessary to develop the instrument. The interviewer will require a laptop computer/handheld computer to administer a computer-assisted questionnaire.

Causes and Treatments of Known Infertility

Questions to assess a participant’s experience with infertility
These questions are used to determine the cause of the participant’s or his or her partner’s infertility and the treatments that he or she may have sought. It is important to measure because it can be related to birth outcomes (e.g., multiple births). Infertility may also be associated with gene/environmental interactions.
