Hormonal serum profiles and follicular development after intramuscular and pulsatile intravenous administration of human menopausal gonadotrophin
European journal of endocrinology ·doi:10.1530/eje.0.1330057

A study was performed to compare, in a randomized way, the effect of pulsatile intravenous (i.v.) and intramuscular (im) human menopausal gonadotrophin (hMG) administration on hormonal serum profiles and follicular development in in vitro f…

Endometrial epithelial cells in peritoneal fluid during the early follicular phase
Fertility and Sterility ·doi:10.1016/s0015-0282(16)54119-3

Peritoneal fluid (PF) was obtained during the early follicular phase in 24 women at laparoscopy as part of infertility investigation. The cells present in PF were pelleted and cultured. Developing endometrial epithelial cell colonies were i…

Retrograde seeding of endometrial epithelial cells by uterine-tubal flushing
Fertility and Sterility ·doi:10.1016/s0015-0282(16)54533-6

OBJECTIVE: To estimate the amount of endometrial epithelial cells in peritoneal fluid (PF) after uterine-tubal flushing (40 mL) throughout the menstrual cycle. DESIGN: We cultured the cell pellet of flush medium present in the peritoneal c…

The differences between findings at laparoscopy and at subsequent fertility surgery
European journal of obstetrics, gynecology, and reproductive biology ·doi:10.1016/0028-2243(86)90146-2

In a series of 42 patients, the findings during fertility microsurgery were compared to the findings at both laparoscopy performed by referring gynaecologists and re-laparoscopy performed in our regimen. Since significantly fewer discrepanc…

Behavior of cultured glandular cells obtained by flushing of the uterine cavity
Fertility and Sterility ·doi:10.1016/s0015-0282(16)48683-8

In 77 of 115 cultures from uterine/tubal flushes performed in women undergoing diagnostic laparoscopy for reasons of infertility, epithelioid colonies of "tadpole-like" cells appeared. In cultured jet washings from the uterine cavities in w…
