Journal ArticleDOI
The dynamics of rapid sperm transport through the female genital tract: evidence from vaginal sonography of uterine peristalsis and hysterosalpingoscintigraphy
TL;DR: Data indicate that rapid transport of the spermatozoa through the female genital tract is under the endocrine control of the dominant follicle, ensuring the preferential accumulation of spermatozosa at the site of fertilization.
Journal ArticleDOI
The pathophysiology of endometriosis and adenomyosis: tissue injury and repair
TL;DR: A physiological model is proposed that provides a comprehensive explanation of the local production of estrogen at the level of ectopic endometrial lesions and the endometrium of women affected with the disease, involving local estrogen production in an estrogen-sensitive environment normally controlled by the ovary.
Journal ArticleDOI
Pregnancies following chronic intermittent (pulsatile) administration of Gn-RH by means of a portable pump ("Zyklomat")--a new approach to the treatment of infertility in hypothalamic amenorrhea.
TL;DR: The purpose of this communication to present this new method of treatment and the successful induction of the first two pregnancies with this method in two patients with severe hypothalamic amenorrhea.
Journal ArticleDOI
Adenomyosis in endometriosis – prevalence and impact on fertility. Evidence from magnetic resonance imaging
TL;DR: With a prevalence of up to 90%, uterine adenomyosis is significantly associated with pelvic endometriosis and constitutes an important factor of sterility in endometRIosis presumably by impairing uterine sperm transport.
Journal ArticleDOI
Uterine hyperperistalsis and dysperistalsis as dysfunctions of the mechanism of rapid sperm transport in patients with endometriosis and infertility
TL;DR: Hysterosalpingoscintigraphy during the early, mid- and late follicular phases revealed that hyperperistalsis in the early and mid-follicular phases of patients with endometriosis resulted in a dramatic increase in the transport of inert particles from the vaginal depot, through the uterus into the tubes and also into the peritoneal cavity.
