Most women did not express regret after their husband's vasectomy and the probability of regret was similar to sterilized women. However, when there was substantial conflict between a woman and her husband before vasectomy or tubal sterilization, the probability of subsequent request for reversal was increased.

Thyroid hormone preparations comprised over 1% of all prescriptions filled by retail pharmacies during 1988 in the conterminous United States, i.e., the 48 contiguous states. Their large market share gives the patterns of their use substantial public health importance. This article describes prescription thyroid hormone use in the United States from 1960 through 1988, using pharmaceutical marketing research data collected from panels of retail pharmacies and office-based physicians. Although the use of natural products has declined by over 50% since 1960, about one fourth of all thyroid hormone prescriptions were for natural preparations as recently as 1988. Per capita thyroid mentions (i.e., patient-physician contacts during which a thyroid agent of any kind was recommended, prescribed, dispensed, administered, ordered to be given by a hospital, or given as a sample) doubled during this period among those over 59 years old. Per capita mentions for synthetic thyroid products increased fourfold and tenfold among men and women in this age group, respectively. Use for weight loss, despite the label's boxed warning indicating it to be ineffective and potentially dangerous, has diminished but persists. Obesity was second only to hypothyroidism among the diagnoses underlying thyroid product mentions.

Age and reproductive stage are the most important determinants of FSH levels in US women; however, FSH by itself has limited utility in distinguishing among women in different reproductive stages.
