PIP: During 1994 clinical trials of a male hormonal contraceptive method (weekly injections of TE) at a center in England, questionnaires, focus group discussions, and individual interviews were used to ascertain the acceptability of the method for participants and their female partners. Of the 27 men who completed the clinical trial in the center, 23 (86%) of their partners participated in focus group discussions or interviews. Most of the women had experienced difficulty with the methods of contraception they had used in the past; others, who had been successfully using the female pill for a number of years, wanted a break from it. The majority of the focus group participants expressed satisfaction with the form of male contraceptive method under study. Couples dismissed the condom as a viable option, and many men rejected vasectomy because it was a surgical procedure that had poor reversibility. More than 50% of the female respondents felt their partners had shown increased irritability and libido. In some cases, this correlated with known peak blood levels of testosterone in the treatment regimen (1 or 2 days after injection); these were not perceived as problematic for most of the cases. Women, in several instances, identified changes in their partners' moods of which the men were unaware. Two participants discontinued their participation in the trial because their changes in mood were unacceptable to their partners. Nearly 40% of the female respondents said they experienced an increase in enjoyment of sexual intercourse as a result of confidence in the method and relief from responsibility for contraception. The injectable method was perceived by several participants in the clinical trials to be superior to a pill because nothing had to be remembered.
