Filter by:Polycystic ovary syndrome (PCOS) is one of the most common endocrinopathies, affecting 5% to 10% of women of reproductive age. Women with PCOS suffer from anovulatory infertility. Following lifestyle modification with weight reduction in obese PCOS women, clomifene citrate (CC) is considered the first line treatment for ovulation induction (OI) in these women. 75-80% of women will ovulate after CC administration. However, there is a discrepancy between the ovulation rate and pregnancy rate, which was reported to be 22% per each ovulating cycles after CC. Other alternatives, including gonadotropin injections and laparoscopic ovarian drilling, carried different disadvantages, such as costly treatment and risks of ovarian hyperstimulation syndrome and multiple pregnancy rate in gonadotrophin therapy and surgical risks and risk of ovarian failure in surgical treatment. The use of aromatase inhibitor, letrozole (LTZ), in reproductive medicine started in 2001. After this publication, there have been many groups of investigators studying the use of LTZ either in OI or ovarian stimulation in IVF cycles. A large multicentre randomized trial reported a significantly higher ovulation rate and live-birth rate comparing LTZ with CC. In majority of the publications, the multiple pregnancy rate was lower in LTZ group than in CC group. This can be attributed to the higher chance of monofollicular development after LTZ compared with CC. However, there is no information comparing the hormonal profile and follicular development after letrozole and CC. Mild ovarian stimulation using LTZ or CC in conjunction with intrauterine insemination is commonly offered to ovulatory women with unexplained infertility, minimal endometriosis or mild factor to improve the pregnancy rate. There is again no information comparing the hormonal profile and follicular development after letrozole and CC in ovulatory women. The aim of this study is to compare the hormonal profile after the use of LTZ and CC in anovulatory PCOS women and ovulatory women with unexplained subfertility. The hypothesis is that the FSH risk after LTZ is shorter than that of CC.
The objective of the present randomized controlled study is to compare clinical effectiveness and safety of freezing all embryos followed by frozen-thawed embryo transfer (FET) compared to fresh embryo transfer, in women undergoing IVF treatment.
440 women with expected poor ovarian response undergoing IVF/ICSI (intracytoplasmic sperm injection) will be randomly divided into 2 groups using computer generated random numbers . Group 1 ( study group) will receive Dehydroepiandrosterone (DHEA) 25 mg ( DHEA 25mg, Natrol , USA) t.d.s daily for 12 weeks before starting IVF/ICSI cycle. Group 2 ( control group) will receive a placebo. Patients included in the study will be subjected to full history taking and clinical examination. On the second day of menstruation serum FSH, LH, Prolactin and Oestradiol will be assessed and the antral follicular count (AFC) will be assessed using a vaginal ultrasound scan. AFC will be defined as the number of follicles measuring 3-10mm. All patients will have gonadotropin antagonist protocol with Human menopausal gonadotrophin (HMG) stimulation until the day of (Human chorionic gonadotrophin (HCG) administration. On the day of HCG administration, ovarian ultrasound scan will be performed using a transvaginal probe. Oocytes will be aspirated 34-36 hours after HCG administration. Oocytes will be fertilized and embryos will be transferred. Both groups will be compared regarding the proportion of pregnancy.
The study will include 100 women with unexplained recurrent implantation failure undergoing IVF/ICSI cycle. Patients fulfilling the inclusion criteria will be randomised into two groups. Study Group: This group will include 50 women with unexplained recurrent implantation failure undergoing a trial of IVF/ICSI. This group will receive intravenous infusion of intralipid 20%, on the day of oocyte retrieval, a second dose on/ the following day of positive pregnancy test and a final dose 2-3 weeks later when attending for pregnancy scan. Control Group: This group will include 50 women with unexplained recurrent implantation failure undergoing a trial of IVF/ICSI. This group will receive intravenous infusion of placebo, on the day of oocyte retrieval, a second dose on/ the following day of positive pregnancy test and a final dose 2-3 weeks later when attending for pregnancy scan.
Four hundred and fifty women with endometriosis will be divided into 3 equal groups using computer generated random numbers: Group 1 will have up to 4 stimulated intrauterine insemination (IUI) cycles, group 2 will have up to 4 unstimulated cycles, women who do not become pregnant after the 4 cycles in groups 1 and 2 will be advised to have regular intercourse at the expected time of ovulation. Group 3 will be the control group will be advised to have regular sexual intercourse at the time of ovulation for 4 months
Four hundred and fifty women with mild male factor infertility will be divided into 3 equal groups using computer generated random numbers: Group 1 will have up to 4 stimulated IUI cycles, group 2 will have up to 4 unstimulated cycles, women who do not become pregnant after the 4 cycles in groups 1 and 2 will be advised to have regular intercourse at the expected time of ovulation. Group 3 will be the control group will be advised to have regular sexual intercourse at the time of ovulation for 6 months
The purpose of this study is to investigate the effect of DHEA for treatment of subfertile patients with poor ovarian reserve and post-treatment evaluation of IVF outcome.
In this study the aim is to compare the effect of the type of anaesthetic drug used during oocyte retrieval on fertilization rates of oocytes retrieved after ovarian stimulation for in-vitro fertilization.
Records of women who had in vitro fertilization (IVF) or intra-cytoplasmic sperm injection (ICSI) in Dar AlTeb sub-fertility center will be reviewed and the follicular sensitivity index (FSI) will be calculated and correlated with pregnancy.
Dropout rates for fertility treatments are high. This study will examine the rate of patients that drop out during any type of subfertility work up or treatment. Furthermore, we will determine what reasons for discontinuation are and we will identify the demographic characteristics of the couples and the prognostic factors for drop out during assessment or treatment at a Fertility Centre in the Isala (Zwolle), Erasmus University Centre (Rotterdam), Elisabeth Twee Steden Hospital (Tilburg), Reinier de Graaf Group (Voorburg), St Antonius Hospital (Nieuwegein), Maxima Medical Centre (Veldhoven) and Noordwest Hospital Group (Den Helder/Alkmaar) in The Netherlands.
