Showing papers in "Fertility and Sterility in 1976"

TL;DR: The diagnosis can only be made clinically on the basis of a well-timed endometrial biopsy that is read histologically as 2 or more days out of phase with the next period in at least two cycles.

TL;DR: The diluent proved to be a favourable medium for significantly delaying the deterioration of sperm progression over a 24-hour period and yielded sperm suspensions free of seminal plasma and populations of spermatozoa that had increased motility ratings compared with the original semen.

TL;DR: The hypothesis is introduced that the shaking phenomenon is due to an interaction between sensitized spermatozoa and the glycoprotein micelles in cervical mucus and not after contact with the aqueous fraction.

TL;DR: In an in vitro assay human spermatozoa penetrated the zona pellucida of 38.8% of 773 human oocytes recovered from the ovaries of cadavers as mentioned in this paper.

TL;DR: The oxygen tension in the oviductol fluid of adult female rhesus monkeys was measured by means of miniaturized, flexible, oxygen probes between days 5 and 22 of the menstrual cycle.

TL;DR: Scrotal thermography is a valuable screening method for the detection of spermatic venous reflux in patients with palpable and subclinical varicocele and the technique allows selection of patients to be subjected to retrograde venography.

TL;DR: The results presented here suggest that chronic administration of the GnRH analog inhibits ovarian steroid output either by direct action of the analog on the ovary or indirectly through qualitative or quantitative changes in levels of luteinizing hormone and follicle-stimulating hormone.

TL;DR: In one man with hyperprolactinemic oligospermia, treatment with bromocriptine yielded significant improvement in sperm count (to normal values), and there was no correlation among serum levels of follicle-stimulating hormone, luteinizing hormone, sperm count, and serum prolactin values.

TL;DR: Changes in the temperature, pH, and partial pressure of oxygen in the cervical canal and cavum uteri were measured in women with or without an intrauterine device and in the uteri of rats throughout the cycle, and the PO2 exhibited significant variations.

TL;DR: In this paper, a 10-year period 295 varicocelectomies were performed in subfertile males and the results of follow-up studies indicate the following: (1) Semen quality improved in a meaningful manner in 58% of men following VCC, except at times for motility.

TL;DR: In this article, the authors found that basal body temperature correlated with serum luteinizing hormone (LH), progesterone, and estradiol or urinary estrogen levels assayed serially during one menstrual cycle.

TL;DR: The Sims-Huhner test should be an integral part of an infertility investigation, but it must not be used as a substitute for semen analysis.

TL;DR: In this article, a system was developed for the perfusion of the rabbit ovary in vitro, at laparotomy, the ovarian artery was cannulated and perfused with M 199 tissue culture medium containing insulin and heparin, then removed with its vascular pedicle intact.

TL;DR: Therapeutic trials for this oligospermic patient showed that an increase in cell count to values in the low-normal range and a drastic reduction in the percentage of round-headed cells could be achieved and the Schirren and Holstein type must be regarded as absolutely infertile due to the absence of an acrosome and its intrinsic enzymes.

TL;DR: The data support a physiologic role for follicular fluids in the process of fertilization and indicate that removal of sperm-bound seminal plasma components is a prerequisite to efficient induction of the acrosome reaction.

TL;DR: The dystopic position of the maldescended testis appears to superimpose a second insult on what very likely may be an inherent abnormality in the cryptorchid testis, the latter accounting, perhaps, for its abnormal extrascrotal position.

TL;DR: In this paper, the effects of pseudopregnancy and conservative surgery on fertility and the need for subsequent surgery with respect to the extent of the disease at the time of initial diagnosis in patients with endometriosis externa were compared.

TL;DR: In this article, the existence of male infertility in hyperthyroidism and the mechanisms adversely affecting spermatogenesis therein are discussed. But little attention has been given to the existence and mechanisms of these disorders.

TL;DR: In this paper, the nucleoproteins of spermatozoa from infertile, oligospermic patients affected by partial idiopathic spermatidic arrest were analyzed by means of polyacrylamide gel electrophoresis.

TL;DR: The sexual function of nine patients with severance of sacral nerves bilaterally (five patients) or unilaterally (four patients), performed during operations for radical extirpation of tumors of the sacrum or its vicinity, was studied.

TL;DR: In six of the eight patients with a negative SHT and in the three with a poor SHT, sperm were found in the aspirate, illustrating the limitation of the long-accepted SHT in the prognosis for infertile couples.

TL;DR: Contraception and carbohydrate metabolism was reviewed with the following main topics: frequency of abnormal results types of women at great risk mechanism of action reversibility of change individual steroid effects (estrogens-progestogens) and clinical implications.

TL;DR: A prospective study of effects of vasectomy on the plasma levels of testosterone, estradiol, follicle-stimulating hormone (FSH), and luteinizing hormone (LH) was instituted as mentioned in this paper.

TL;DR: Ovulated rabbit oocytes were fertilized in vitro in chemically defined media supplemented with bovine serum albumin and either cultured up to the expanding blastocyst stage or transferred to recipients after varying periods of culture.

TL;DR: The results suggest that prolactin plays an important role in the energy metabolism of human spermatozoa.

TL;DR: One thousand radioreceptorassays for human chorionic gonadotropin (hCG) for the diagnosis of pregnancy were analyzed under eight categories as mentioned in this paper, including normal and abnormal pregnancy in the first trimester.

TL;DR: The role of the psycholgist in AID treatment was found to be important for careful selection of cases and he can also guide and prepare these couples to face family life in the future.

TL;DR: In this article, the spontaneous contractility of rat epididymis was recorded in vivo and the effects of various autonomic drugs were studied, including Norepinephrine, epinephrine, and orciprenaline.

TL;DR: Carnitine determinations in human seminal fluid were shown to be useful in assessing epididymal and seminal vesicle function and in locating blockages in the male reproductive tract as discussed by the authors.

TL;DR: In this article, a retrospective analysis of 238 endometrial biopsies and simultaneous plasma progesterone determinations performed during the course of infertility evaluations is presented, and the data suggest a high correlation between the two procedures for the detection of ovulation.
