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 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...

Findings of estriol protective action against chemical carcinogens used to induce breast cancer in laboratory animals.

Progesterone levels in the human fetoplacental unit at term were determined by a competitive protein binding method. Progesterone levels in the umbilical vein were always higher than in the umbilical ...

A combination of Decadreon (dexamethasone) and Phenergan (promethazine) was tested in this collaborative study of 240 infertility patients as a means of preventing postoperative adhesion formation aft...

Ten ovulating women were studied to assess the interrelationships of various systemic, hormonal, and reproductive tract changes during normal menstrual cycles. Samples of blood, 24 hour urine specimen...

This article has been designed to review recent developments in the field of hypothalamic hormones involved in the control of reproductive functions. A brief resume of early physiologic and anatomic s...

Summary: Studies on pituitary and ovarian function as assessed by the urinary output of total gonadotrophic activity, the three classical oestrogens, pregnanediol and, in some cases, testosterone and ...

Eighty-six women reached at least 20 weeks' pregnancy in 96 instances, after ovulation induced by clomiphene citrate. Although 37 of the women had 44 previous pregnancies, there had been a high pregna...

To describe normal relationships between the various plasma unconjugated estrogens and progesterone during the second half of human pregnancy, the plasma concentrations of progesterone, 17-hydroxyprog...

A study was undertaken to determine whether solitary progesterone as says performed on serum samples obtained in the midluteal phase would provide the clinician with a convenient indicator that ovulat...

Following the total removal of luteal tissue, circulating plasma progesterone, intrauterine pressure, oxytocin response, and clinical progress in abortion were determined sequentially in 12 first-trim...

PROSTAGLANDINS (PGs) are being used increasingly as abortifacients although their precise mechanism of action is uncertain. One of the compounds frequently used is PGF2α, which has been shown to stimu...

A METHOD IS DESCRIBED FOR ANALYZING THE ASSOCIATION OF THE OPIATE NARCOTIC LEVORPHANOL WITH BRAIN TISSUE INTO THREE COMPONENTS: nonsaturable, saturable nonspecific, and saturable stereospecific. The m...

The use-effectiveness of oral contraception and intrauterine contraception was studied in 3 family planning centers in the United States: Grady Memorial Hospital in Atlanta, Georgia; State University ...

Some of the psychological influences on contraceptive misuse and rejection are presented, ranging from denial (of the possibility of pregnancy), guilt, sexual identity conflicts, to fear, opportunism ...

The extended use-effectiveness of IUD and oral pills as measured by 1) their theoretical effectiveness 2) consistency of use and 3) continuation of use in preventing unwanted pregnancies was studied f...

One hundred and thirty-five patients diagnosed as ovulatory failure have been treated in our clinic since 1966. One hundred and eighteen of these have been treated with clomiphene citrate, or more rec...

Plasma progesterone concentration was determined in the maternal peripheral vein, umbilical vein, uterine vein, and both ovarian veins at elective cesarean section in term pregnancy. In 10 cases plasm...

From among a group of women with apparently normal menstrual cycles, 7 cycles with short luteal phases were identified. These cycles were characterized by grossly normal FSH and LH patterns although t...

Plasma levels of progesterone* were measured during normal human pregnancy by a sensitive and rapid competitive protein binding technique. During the first half of gestation 440 determinations in 321 ...

Clomiphene citrate, in selected patients, is an effective agent for the treatment of infertility due to anovulation. An adequate laboratory and physical evaluation of each individual patient is essent...

A method to measure plasma progesterone by gas-liquid chromatography is presented. The procedure allows for the preparation of a plasma progesterone extract clean enough for accurate submicrogram quan...
