Showing papers in "Fertility and Sterility in 1974"

TL;DR: This study found an average volume of ejaculate and an average sperm concentration that are considerably lower than in the earlier studies reported, and it is suggested that studies be undertaken to determine whether some factor has significantly altered or influenced the male potential fertility rate.

TL;DR: A retrospective study of 254 infertile men with serum sperm agglutination titers ranging from 4 to 1024 determined by the Kibrick test between 1954 and 1968 and reexamined in the 1970s is presented as mentioned in this paper.

TL;DR: Overall, 498 follicles were aspirated and 217 oocytes collected; the average recovery was 3 per patient and the mean follicular diameter was 9.1 mm in infertile and 8.0 mm in fertile patients (p less than .05).

TL;DR: A steroid danazol (17-alpha-Pregn-4-en-20-yno(23-d)-isoxazol-17-ol) possesses a marked separation of pituitary gonadotropin inhibitory activity from overt sex hormonal activities that produces a dose-related decrease in the weights of ventral prostate seminal vesicles and testes of mature male rats.

TL;DR: The Progestasert system combines the advantageous features of IUDs and oral minidose progestogen preparations as mentioned in this paper, which can continuously deliver progesterone for 1 year to the uterine lumen and endometrium.

TL;DR: In this paper, the long-range physiological effects of vasectomy spermatozoa and serum from 30 vasectomized men and 26 rhesus monkeys were tested to determine if antibodies against spermatoza are formed in vasectomy males and whether sperm-immobilizing antibodies were detected within 2 weeks after vasectomy, and the average spermagglutinin titer increased over time in human samples while decreasing and remaining low in most of the monkey samples.

TL;DR: In this article, it was shown that cyclic adenosine monophosphate (AMP) and human follicular fluid (HFF) induced metabolic and surface changes in human spermatozoa capacitation in other animal species.

TL;DR: In this article, the concentration of prostaglandin (PG) F2 alpha in human oviductal fluid was determined and the histological localization of PGF2 alpha was correlated with the menstrual cycle to illuminate possible roles of ovulatory PGF 2 alpha in luteolysis.

TL;DR: A study designed to define the oscillatory pattern of plasma levels of testosterone luteinizing hormone (LH) and follicle-stimulating hormone (FSH) in 4 young adult men was carried out as discussed by the authors.

TL;DR: A series of rabbit fallopian tube reanastomoses performed microsurgically have shown that tuboplasty under the microscope is a practical proposition and it is hoped that the greater precision offered by these techniques may improve the results previously obtained in this field.

TL;DR: 6 men with complete or partial loss of ejaculation as a result of retroperitoneal lymphadenectomy were treated with an intravenous injection of 60 mg synephrine, which stimulates adrenergic alpha-receptors, and temporary restoration of fertility was thought to be due to an increase in bladder neck tone and prevention of backflow of semen into the bladder.

TL;DR: The effects of albumin magnesium and zinc on human sperm survival in different fractions of split ejaculates were studied in this article, where the effect of these prostatic factors on the survival of spermatozoa in the last 1/2 of the ejaculate was investigated.

TL;DR: The object of this paper is to review all the hypothese related to the innervation structure and function of the vas and suggest simple and effective methods of reversible vasectomy.

TL;DR: Silastic capsules of Norgestrienone 17 alpha-ethinyl-17-hydroxy-estra-4 9 11-trien-3-one were inserted subcutaneously in the anterior forearm or in the upper gluteal region of 503 women of childbearing age.

TL;DR: It was found that spermatogenesis 2 to 3 weeks after vasectomy remained unchanged with accumulation of spermatozoa in the tubules, while between 100 and 300 days, occasional mature sperm were found in thetubules indicating a return of sperMatogenesis.

TL;DR: The results add credence to the argument that chromosome aberation may play a role in the causal background of recurring abortions.
