Changes in plasma LH, testosterone, and estrogens were investigated throughout reproduction and molt in free-living male and female emperor (Aptenodytes forsteri) and adelie (Pygoscelis adeliae) penguins. In both sexes and species, plasma LH and gonadal steroids were severalfold above basal level at the time of arrival on the breeding grounds, suggesting(More)
The first of a second generation of slow-release injectable contraceptives is the norethindrone (NET) microspheres with a 90-day duration of action. It was evaluated at 65-mg and 100-mg doses for safety and contraceptive effectiveness in two randomized, single-blind trials among 131 women: 94 women for 12 months and 37 women for 6 months. The 6-month trial(More)
The efficacy of transcervical insertions of quinacrine hydrochloride pellets to produce tubal occlusion has been evaluated in a study of 139 women in Santiago, Chile. At one year, the pregnancy rate was 3.1%, an acceptable rate for a nonsurgical method of female sterilization.
The safety and efficacy of the repeated transcervical instillation of quinacrine hydrochloride in a suspension of 5 ml of 2% Xylocaine was evaluated in 200 patients. All instillation procedures were performed during the proliferative phase of the menstrual cycle: the second instillation was made in the first menstrual cycle following the initial(More)
The surgical, immediately postoperative and delayed postoperative complications and complaints associated with spring-loaded clips and electrocoagulation as techniques of tubal sterilization at laparoscopy were evaluated in a comparative study. Each of the two techniques was randomly assigned to 150 subjects. All sterilizations were performed as outpatient(More)
Among 2283 patients, rates of technical failure, technical difficulty, and operative and early postoperative complications were evaluated for different methods of tubal occlusion at laparoscopy: electrocoagulation (980 cases), spring-loaded clip application (991 cases), and Silastic band application (312 cases). Rates of technical failure and technical(More)
Workers in rural areas earn lower wages than nonrural workers and previous evidence has attributed these differences to lower returns to worker characteristics. This paper builds on that data by examining racial and gender differences within the broader group of rural workers. While there is extensive evidence on both the structure of wages and the source(More)
Recently-delivered women who wish to avoid pregnancy should initiate contraception before ovulation. Since the return of ovulation is not predictable, regardless of the woman's lactation status and duration of postpartum amenorrhea, contraception should be initiated as soon as is reasonable after delivery. The choice of contraceptive method will depend on(More)
To evaluate the feasibility and safety of performing laparoscopic sterilization immediately after a normal delivery, 46 patients were studied. All sterilizations were performed within 48 hours of delivery, using a single puncture technique with cautery and separation of the uterine tubes, under a neuroleptanalgesic. A description of the technique, the(More)
