Effect of seminal plasma application to the vaginal vault in in vitro fertilization or intracytoplasmic sperm injection treatment cycles-a double-blind, placebo-controlled, randomized study.

PURPOSE: To study whether intravaginal application of seminal plasma after follicle aspiration has the potential to increase implantation and clinical pregnancy rates after IVF-ET. METHODS: We conducted a prospective, double-blind, placebo-controlled randomized study of 230 patients undergoing IVF-ET cycles. 500 µL of Fresh seminal plasma from the patient's partner or culture medium (placebo) were injected in the vaginal vault just after follicle aspiration. The main outcome measured was ongoing clinical-pregnancy rate. RESULTS: After ET cancellation in ten patients due to lack of fertilization or embryo cleavage, 220 embryo transfers (103 and 117 in the study and control groups) resulted in a clinical pregnancy rate of 36.9 % and 29.1 % for the study and control groups, corresponding to a relative increase of 26.8 %. After an early pregnancy loss of 13.1 % (5/38) and 23.5 % (8/34) in the study and control groups respectively an ongoing pregnancy rate of 32.0 % (33/103) and 22.2 % (26/117) was achieved corresponding to a relative increase of 44.1 %. Multivariate logistic regression analysis adjusted for study group, age, infertility, and cycle characteristics did not demonstrate any parameter that could predict occurrence of clinical pregnancy rates after IVF-ET. CONCLUSIONS: Patients who underwent SP intravaginal insemination after oocyte pick-up reached higher implantation and clinical pregnancy rates following ET compared to controls, although the difference did not reach statistical significance. More studies and variable methodologies may clarify the potential clinical effect of SP in improving live birth rates after ART.

Surrogate in vitro fertilization outcome in typical and atypical forms of Mayer-Rokitansky-Kuster-Hauser syndrome.

BACKGROUND: The genital malformations in Mayer-Rokitansky-Küster-Hauser syndrome (MRKH) are frequently accompanied by associated malformations whose forms were recently classified as typical (isolated uterovaginal aplasia/hypoplasia) and atypical (the addition of malformations in the ovary or renal system). The aim of this study was to compare the surrogate IVF performance of women with typical and atypical forms including their chances of achieving pregnancy. METHODS: The follow-up data on a total of 102 cycles of surrogate IVF in 27 MRKH patients treated in our department between 2000 and 2010 were analysed. Twenty patients with the typical form who underwent 72 IVF cycles were compared with seven patients with the atypical form who underwent 30 IVF cycles. The various examined parameters of these intended mothers were age, hormonal profile during controlled ovarian hyperstimulation and laboratory outcome. RESULTS: The mean number of gonadotrophin ampoules needed for stimulation and treatment duration was significantly higher in the atypical form (3600 ± 1297IU for 13 ± 2.3 days versus 2975 ± 967 IU for 11.6 ± 1.6 days, P≤ 0.01). Serum estradiol and progesterone levels measured on the hCG administration day were similar. A significantly higher mean number of follicles 12.6 ± 6 versus 8.9 ± 5.4, P≤ 0.03, metaphase II (MII) oocytes 8.7 ± 5.1 versus 6.7 ± 4.8, P≤ 0.05, fertilizations 6 ± 3.6 versus 4.4 ± 3.3, P≤ 0.03 and cleaving embryos 5.7 ± 3.8 versus 4.1 ± 3.3, P≤ 0.01 were available in patients with the typical form compared with those with the atypical form, respectively. There was no significant difference in fertilization rate, cleavage rate or the mean number of transferred embryos. Embryo quality of the transferred ones and pregnancy rate per cycle were also similar between the two groups. CONCLUSIONS: Women with the typical form of MRKH needed fewer gonadotrophins and for a shorter duration for ovarian hyperstimulation. The mean number of follicles, oocytes, MII oocytes, fertilizations and cleaving embryos was higher among women with the typical form. Pregnancy rates were similar since the available number and quality of transferred embryos to the surrogate mother were not affected.

A unique biological in-vivo model to evaluate follicular development during in-vitro maturation treatment.

The aim of this study was to identify the size in which the dominant follicle acquires the ability to produce a functional corpus luteum. This observational study includes 15 women with ovulatory cycles who underwent human chorionic gonadotrophin (HCG)-primed in-vitro maturation (IVM) treatments without embryo transfer. All patients received subcutaneous injection of HCG 10,000 IU 38 h prior to oocyte retrieval. Five to seven days following retrieval, serum concentrations of progesterone and oestradiol were measured along with ultrasound scan measuring the antral follicle count. Using receiver operating characteristic curves and the Youden index (J), this study clearly shows that the diameter of the dominant follicle at the time of the LH surge is a good predictor for its ability to form a progesterone-producing corpus luteum (area under the curve 0.94). These findings revealed that the dominant follicle develops the competence to form a corpus luteum, signified by the production of more than 10 nmol/l serum progesterone at 5-7 days from oocyte retrieval, as soon as it acquires a diameter of 10.5-12.0mm. In addition, a new cohort of viable antral follicles can be identified as early as 5-7 days following IVM oocyte retrieval.

Fertility preservation treatment for young women with autoimmune diseases facing treatment with gonadotoxic agents.

OBJECTIVE: To describe a case series of seven women with SLE and other systemic autoimmune rheumatic diseases (SARDs) who required cyclophosphamide therapy and underwent fertility preservation treatments. METHODS: Of the seven patients reported here, five women had SLE with nephritis, the sixth had immune thrombocytopenia purpura (ITP) and the seventh had microscopic polyangiitis (MPA) with renal involvement. All women were nulliparous and younger than 35 yrs. RESULTS: Patients with SLE underwent in vitro maturation (IVM) of immature oocytes aspirated during a natural menstrual cycle followed by vitrification of the matured oocytes if a male partner was not available, or vitrification of embryos if one was available. The patient with ITP and the patient with MPA underwent gonadotropin ovarian stimulation followed by oocyte or embryo vitrification. All women completed fertility preservation treatment successfully and mature oocytes or embryos (36 and 13, respectively) were vitrified. No complications were associated with this treatment and cytotoxic therapy was initiated as scheduled in all cases. CONCLUSIONS: Oocyte or embryo cryopreservation should be considered for fertility preservation in young women with SARDs who face imminent gonadotoxic treatment. In patients, where gonadotropin ovarian stimulation is deemed unsafe, IVM of immature oocytes, aspirated during a natural menstrual cycle, followed by vitrification or fertilization of the mature oocytes, seems to be safe and feasible. For patients in whom hormonal ovarian stimulation is not contraindicated, this method may be considered depending on the urgency to start cytotoxic therapy.

Postpartum chills phenomenon: is it a feto-maternal transfusion reaction?

OBJECTIVE: To examine the theory that the postpartum shivering phenomenon is related to feto-maternal bleed during the third stage of labor. METHODS: One hundred laboring low-risk women who had a normal vaginal delivery were observed for the presence of postpartum chills. The duration of the first and second stages of labor changes in body temperature, maternal and fetal blood types and the use of epidural anesthesia were recorded. Following the delivery maternal blood was examined for the presence of fetal red blood cells using the Kleihauer-Betke stain. RESULTS: Complete data was available in 97 patients. Post-partum chills occurred in 31 of them (32%). Women with and without chills were similar in their maternal and gestational age, the use of epidural anesthesia, and length of second stage of labor. Women with chills delivered smaller babies but the difference did not reach significance. Maternal-fetal blood group incompatibility was significantly more common among shivering than non-shivering women (48% vs. 20% respectively, p=0.006). Kleihauer-Betke test was positive in 11 women. The only two women in this group who experienced chills had maternal-fetal blood group incompatibility. CONCLUSION: Post-partum chills are a common phenomenon. It may be the clinical presentation of feto-maternal transfusion reaction. The small number of positive Kleihauer-Betke tests may reflect its low sensitivity in the detection of small feto-maternal bleeds.
