[Single embryo transfer: is Scandinavian model valuable in France?].

The aim of infertility treatment is clearly to obtain one healthy baby. If the transfer of a top quality single embryo could provide a baby to all the patients, there would be no more discussion. The problem is that, nowadays, French pregnancy rates after fresh embryo or frozen embryo transfer are not the same as in Nordic countries.

[Intra-uterine insemination: ovarian stimulation or not?].

Conflicting results have been published about intra-uterine insemination efficacy. In many studies, success rates is due to ovarian stimulation and number of follicles. In the present fight against multiple pregnancies, ovarian stimulation is discussed and present pregnancy rates are weak.

[Oocyte and embryo quality in polycystic ovary syndrome].

Objective: To compare oocyte and embryo quality in women with Polycystic Ovary Syndrome (PCOS) and in women with normal ovulation.

Patients And Methods: Forty women with PCOS underwent a total of 67 In Vitro Fertilization (IVF) or Intracytoplasmic Sperm Injection (ICSI) cycles. The control group consisted of women, of the same age, who underwent IVF (for tubal infertility) or ICSI (for male factor infertility) in the same period.

Blastocyst stage transfer: the real benefits compared with early embryo transfer.

With the development of commercially available sequential media it is now possible to grow human embryos to the blastocyst stage without feeder cells. The transfer of blastocysts offers several advantages, the most important being synchronization of the embryos with the uterine endometrium and selection of the best quality embryos with a high implantation potential. This study was conducted to compare the efficiency of day 2 and day 5 transfer in a prospective randomized trial involving patients for whom embryo selection was possible (i.

[Comparative randomized controlled study between human follicle- stimulating hormone (FSH-HP) and human menopausal gonadotropins (hMG) in in vitro fertilization].

We present the results of a prospective randomized trial comparing the issue of IVF-ET and of ICSI when either highly purified human folliculostimulin (FSH-HP) or human menopausal gonadotrophin (hMG) is used. There seems to be a trend to a better rate of ongoing pregnancies when FSH-HP is used although not statistically significant. The study has been stopped due to the lack of hMG.

Results of planned in-vitro fertilization programming through the pre-administration of the oestrogen-progesterone combined pill.

The use of an oestrogen-progesterone combined pill permits the induction of ovulation in the absence of any developing follicle. Two treatments were compared. In the first, patients received no prior treatment before stimulation.

[Results of preparatory surgery for in vitro fertilization with embryo transfer].

68 cases out of a total of 407 patients who were destined to have IVF (16.7%) had most adhesions in the pelvis which made the ovaries inaccessible for laparoscopic recovery, in the two years between September 1981 and September 1983. Using very severe criteria for selection we rejected 46 cases as unsuitable for surgery at that time.
