To test the postulate that endogenous opioid peptides may be involved in the neuroendocrine mechanisms controlling the frequency and amplitude of LH pulses, saline and an opioid receptor antagonist, n...

In order to assess a possible influence of endogenous opioids upon gonadotrophin secretion in women, we examined the effects of i.v. administration of 10 mg naloxone, a specific opiate antagonist, in ...

A homogeneous group of 214 infertile women with endometriosis treated at the Johns Hopkins Hospital from 1960 to 1979 received conservative surgery as the sole therapeutic modality. Among this group, ...

The increasing importance of an ectopic pregnancy as a cause of maternal death presents a challenge that will be met when primary care physicians combine a high index of suspicion with the ability to ...

Since the isolation of the enkephalins five yr ago, there has been an explosive increase in knowledge concerning the effects of the opiates and opioid peptides. This review deals with the interactions...

The fertile period of the human menstrual cycle consists of those days on which sexual intercourse can result in a pregnancy. Its duration is determined by the functional life span of the gametes with...

A case-control study of the epidemiology of preterm delivery was undertaken at Yale-New Haven Hospital in Connecticut during 1977. The study population consisted of 175 mothers of singleton preterm in...

A 2-year international study involving NFP (natural family planning) associations in 5 countries (Canada Colombia France Mauritius U.S.) was conducted to evaluate statistically the effectiveness of th...

The ovulation method provides a woman with an awareness of her cervical mucus pattern. This enables her to mark the beginning and end of the fertile phase of the cycle as well as the time of maximum f...

Two antisera, Y-10 and Y-18 were raised in rabbits against synthetic human beta-endorphin conjugated to bovine serum albumin and keyhole limpet haemocyanin respectively. Antiserum Y-10 has been shown ...

A review of the extensive literature on the subject indicates that sex hormones have been associated with a wide variety of adverse clinical conditions following usage during pregnancy. About 230 case...

The authors present "Billing" ovulation method as natural family planning.

The treatment of pelvic inflammatory disease depends upon the etiology of the condition. Pelvic infection (PI) after parturition and abortion, gynecologic surgery, and a variety of invasive procedures...

Two cases of ovum retention occurring in postovulatory follicles are described. The ova were recovered at laparoscopy by aspiration of decompressed ovulatory follicles, one during a natural cycle and ...

The management of patients with premature rupture of membranes (PROM) poses one of the most serious dilemmas in obstetrics since PROM significantly increases the likelihood of prematurity and serious ...

Wedge resection was performed in 12 patients with polycystic ovarian disease, and cell samples from the cystic follicles were assayed for LH(hCG) receptor using [125I]iodo-hCG as a ligand hormone. Sim...

In previous studies it could be demonstrated that in severe hypothalamic amenorrhea, which is associated with absent or deficient hypothalamic secretion of Gn-RH, ovarian function could be restored by...

The luteinized unruptured follicle syndrome is a frequent phenomenon, occurring in half of our women with regular cycles and infertility. Progesterone concentrations and 17 beta-oestradiol concentrati...

The treatment of hirsute women is controversial and often presents a therapeutic dilemma. Mechanical methods (such as shaving or using depilatories) are safe but often unacceptable to the patient, whe...

A shift in progesterone-to-estradiol balance to estradiol dominance is assumed to be a prerequisite for regular uterine contractions. To antagonize this effect in premature labor 24 consecutive women ...

Cytogenetic analysis of 1000 spontaneous abortions showed 463 to have an abnormal chromosome constitution. The proportion of chromosome abnormalities varied with the gestational age of the abortus and...

Now that principles of NFP have been established specific programs are necessary to disperse information and to teach techniques. The hospital-based NFP program offers the community a needed service a...

Purpose Endometriosis is a benign estrogen-responsive disease which shares some characteristics with malignant tumors such as invasion and unrestrained growth. In this respect, the epidermal growth fa...

Endometriosis was encountered in 66 of 140 patients (47%) who underwent laparoscopy for chronic pelvic pain at Boston Children's Hospital Medical Center. Pelvic pain associated with this diagnosis was...

Plasma progesterone concentrations drawn at the time of endometrial biopsy in 26 infertility patients with histologically documented luteal phase inadequacy were compared with those of 26 infertility ...

Healthy volunteers with regular ovarian function, women taking oral contraceptives, and infertile patients being treated with clomiphene were studied longitudinally from day 7 of the cycle to menstrua...

Three hundred and ninety-six patients were evaluated for primary and secondary infertility between December 1976 and May 1979 at a large referral center. Timed late luteal endometrial biopsies were ro...

The administration of small doses of LHRH at 2-hourly intervals over a 27 day period to a 24-year old patient with Kallman's syndrome resulted in ovulation as indicated by: (1) a biphasic temperature ...

In rhesus monkeys with hypothalamic lesions (which appear to abolish the endogenous production of gonadotropin-releasing hormone), normal ovulatory mestrual cycles were reestablished by an unvarying, ...

Myometrial tissues from pregnant and nonpregnant mature and immature rats were examined for the presence of gap junctions by thin section and freeze-fracture microscopy before and after incubation in ...

Twenty-five women scheduled for hysterectomy for nonmalignant disease participated in the study. Sperm storage in endocervical crypts was examined in three groups of patients: nine women pretreated wi...

Four points on the basal body temperatures (BBT) curve have been correlated with the estimated time of ovulation (ETO), as determined by indirect hormonal parameters, in 74 menstrual cycles from 24 su...

I read with interest the recent article by Wade and associates, "A randomized prospective study of the use-effectiveness of 2 methods of natural family planning: an interim report" (134: 628, 1979). I...

The volume of peritoneal fluid was measured after laparoscopic aspiration in 303 women. Contamination with blood was estimated at 4.2 per cent by haemoglobin assay. In 120 women with regular menstrual...

One hundred and forty-nine patients presenting with infertility underwent two hundred and ten endometrial biopsies as part of a routine infertility evaluation. The initial biopsy was out of phase in 4...

3 cases of stroke in young women of childbearing age are presented to show the severity of illness and mortality in women using oral contraceptives. All 3 patients smoked more than 15 cigarettes a day...

Tubal abrasions were surgically induced in 25 rhesus monkeys following demonstration of tubal patency. Five monkeys received dexamethasone, promethazine, and ampicillin perioperatively, five received ...

Progesterone and human chorionic gonadotrophin (HCG) in serum and pregnandiol in urine were measured in 64 patients admitted to hospital because of threatened abortion. Blood samples were taken and ur...

The concentration of human beta-endorphin (beta h-EP)) was measured in various hypothalamic nuclei, in extrahypothalamic brain regions and in the anterior and posterior lobes of the pituitary using a ...

It is commonplace for gynecologists to refer to "midcycle" ovulation of women. This concept has often led to the routine diagnosis of ovulatory status on day 14 of what is expected to be a 28-day mens...

We describe the opioid properties of a tridecapeptide, the sequence of which corresponds to the NH2-terminal sequence of dynorphin, a novel porcine pituitary endorphin. It contains [Leu]enkephalin. In...
