Alternatives to female sterilization.

With national policies aimed at reaching zero population growth in the shortest possible time, many countries have introduced restrictive legislation and disincentive programs in an attempt to decrease family size norms to 2 or 3 children. As a result, younger women of lower parity are being sterilized, with consequences that will be seen in the years to come. Although female sterilization is usually associated with minimal complications and side effects and is highly effective without continuing motivation or promotion, it has the disadvantage of causing permanent, essentially irreversible sterility. Therefore, it will not be readily acceptable to a large portion of the population. For many women, alternatives must be sought. Reversible methods of female or male sterilization, longacting systemic contraceptives, longacting implants, and immunization against implantation or sperm antigens are potential alternatives, but all are still in experimental stages of development. Intrauterine devices and injectables are the 2 most effective alternatives now available. The use of intrauterine devices with abortion as a backup in case of contraceptive failure ranks high as an alternative to female sterilization.

Serum human placental lactogen (HPL) levels in patients with intact hydatidiform mole.

Serum human placental lactogen (HPL) levels in forty cases of intact hydatidiform mole were measured by radioimmunoassay. The HPL values were generally lower than normal pregnancies of the corresponding period of gestation. However, normal and occasionally higher than normal values were observed in a few cases. Serum HPL level alone is of some clinical use in the diagnosis of hydatidiform mole. When combined with human chorionic gonadotropin (HCG), a low HPL/HCG ratio for the corresponding period of amenorrhoea is a useful index in the diagnosis of hydatidiform mole.
