A personal series of 600 private patients using natural family planning techniques is presented. The total failure rate was 4.7 pregnancies per 100 woman-years. The advantages of this method over conv...

Enkephalin, a natural ligand for opiate receptors is composed of the pentapepides H-Tyr-Gly-Gly-Phe-Met-OH and H-Tyr-Gly-Gly-Phe-Leu-OH. The evidence is based on the determination of the amino acid se...

Sixty in-depth interviews with mothers living in a urban slum of Morocco probed resistances to practicing modern methods of fertility control and began to shed light on some of the reasons family plan...

We conducted a double-blind study to determine the efficacy of 17alpha-hydroxyprogesterone caproate in preventing premature delivery in 43 high-risk patients. Premature delivery did not occur in 18 pa...

Progesterone metabolites and estriol were determined in urine and faeces collected daily from three pregnant women (33–37 weeks) before and during ampicillin administration (2 g/day orally). Two of th...

Epidemiologic studies, retrospective and prospective, were done on 1500 abortions collected from 1966-1972. No secular or seasonal variations were observed. From the analysis of the relative frequenci...

The ability of morphine to block ovulation in animals prompted investigation of the frequency and mechanisms of menstrual abnormalities in women addicted to narcotic analgesics. Menstrual histories ob...

Psychological data was obtained from 1009 couples located in 5 countries who were practicing the temperature-rhythm method of birth control. In the U.S., survey instruments were distributed to 160 cou...

Ingestion of a single tablet containing 2 mg micronized 17beta-estradiol (E-2) produced marked increases in the serum concentrations of E-2 and estrone (E-1) in 9 postmenopausal women. The rise in cir...

The plasma concentration of progesterone (P) has been measured by radioimmunoassay in maternal peripheral vein (M.P.V.) at early pregnancy and in M.P.V. umbilical artery (U.A.) and umbilical vein (U.V...

5alpha-Pregnane-3,20-dione and progesterone were isolated from a pregnancy plasma pool and were identified by using a combination of chromatographic techniques and mass spectrometry. Antibodies to pro...

To develop a practical yet statistically valid means of indicating ovulation and adequacy of corpus luteum function concentrations of plasma progesterone (P) were measured daily during the luteal phas...

The luteal phase plasma progesterone levels of 341 control patients were compared with those in 25 patients with early and 12 patients with advanced breast cancer. There was a significant increase of ...

Summary: The use of clomiphene in gradually increasing doses, in cases of infertility due to anovulation, oligo-ovulation and inadequate luteal phase, led to a high pregnancy rate, particularly in the...

The irregular menses experienced by obese and/or hirsute women were studied by daily measurement of serum LH, FSH, estradiol (E2) and progesterone (P). During 8 cycles of 24 to 157 days, each episode ...

Plasma concentration of estrogen and progesterone were measured during the last 6 days of the menstrual cycle in women with premenstrual tension, and compared with a group of healthy women. Those wome...

A group of infertility patients were evaluated by an endometrial biopsy, timed with a basal body temperature chart, serum luteinizing hormone radioimmunassay to pinpoint ovulation, and daily serum pro...

Plasma progesterone levels were estimated by competitive protein binding in 815 samples from healthy pregnant women with uncomplicated pregnancies. This series includes 32 patients who were followed s...

This paper gives in narrative style those phases of the corpus luteum story in which the author was an active participant. The first part deals with the exciting days at the University of Rochester wh...

The levels of prostaglandins in the human endometrium throughout the normal menstrual cycle were measured by bioassay. The identity of prostaglandin F2alpha and prostaglandin E2 in endometrial tissue ...

The ovulation method of family planning relies on self-recognition of physiological changes occuring around time of ovulation rather than a calendar to enable a couple to avoid sexual intercourse duri...
