Personnel and Training Required
The Longitudinal Investigation of Fertility and the Environment (LIFE) Study is an interviewer-administered survey. 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.

|Average time of greater than 15 minutes in an unaffected individual||No|
|Specialized requirements for biospecimen collection||No|
Mode of Administration
If the participant answers "no" to question 1, the protocol is deemed complete.
Below is a definition from the Mayo Clinic website that may assist researchers in using the Toolkit:
Ectopic pregnancy: Pregnancy begins with a fertilized egg. Normally, the fertilized egg attaches itself to the lining of the uterus. With an ectopic pregnancy, the fertilized egg implants somewhere else. An ectopic pregnancy nearly always occurs in one of the tubes that carry eggs from the ovaries to the uterus (fallopian tubes). This type of ectopic pregnancy is known as a tubal pregnancy. Rarely, an ectopic pregnancy occurs in the abdomen, ovary, or neck of the uterus (cervix).

Question to assess both males’ and females’ pregnancy history. Females are asked about the number of pregnancies, description of pregnancies, and smoking during pregnancy. Males are asked whether they have ever fathered a pregnancy and, if so, the description of the pregnancy.
The purpose of this measure is to assess the demonstrated fecundity and fertility of the individual. This measure can also be used for estimating certain in utero exposures if the research subject is an infant.
The Longitudinal Investigation of Fertility and the Environment (LIFE) Study asks males a comprehensive set of questions regarding their pregnancy history.
