Active clinical trials for "Infertility"

The purpose of the present study is to examine the level of ovarian response and the pregnancy rates among poor ovarian responders treated with a novel treatment protocol with 150μg corifollitropin alfa followed by 300IU hMG in a long GnRH agonist protocol.

To evaluate the effect of pentoxifylline used in preparation of semen samples that will be used for ICSI in infertile men complaining of mild and moderate asthenozoospermia (i.e. cases which does not need motility enhancement prior to ICSI) in comparison to semen samples without pentoxifylline preparation on the outcome of ICSI.

This study is for patients undergoing In Vitro Fertilization (IVF). The investigators are studying the best way to control pain during the egg retrieval process. The egg retrieval involves passing a needle under ultrasound guidance through the vagina into the ovaries to remove eggs that are to be later fertilized. Patients often report this as very uncomfortable. Different fertility clinics across the country use different methods of pain control. All clinics will use intravenous medication to control pain, while some may or may not use local anaesthetic (freezing) in the vagina. Our goal is to find the best way to control pain. Since local anaesthetic injection involves multiple needle punctures and may be painful, the investigators are unsure if local anaesthetic is necessary in addition to the intravenous pain medication. The investigators will conduct a randomized trial where all patients will receive intravenous pain medication, but some will receive local anaesthetic injection and some will receive placebo injection. Patients will be asked to complete a questionnaire on their pain experience after oocyte retrieval. The investigators will then analyze the data and determine whether local anaesthetic actually improves pain when patients are already receiving intravenous pain medications. Through our study, the investigators aim to improve the pain experience of all women undergoing IVF in the future.

The purpose of this study is to investigate levels of progesterone in the luteal phase after various stimulations in the follicular phase and treatment with GnRH antagonist protocol followed by GnRHagonist as induction of ovulation.

The purpose of this study is to determine if growth hormone given 4 weeks before as well as during a cycle of in vitro fertilization will improve outcomes in women who have had previous failure with IVF treatment cycles using high doses of follicle stimulating medications and had a poor response (less than 6 follicles).

The present study is set up to evaluate the efficacy of a programmation by administration of estrogen valerate during 6 or more consecutive days. In this prospective randomised trial, we study the impact of administration of Progynova® during 6, 7,8 9 or 10 consecutive days during the luteo-follicular transition period of the menstrual cycle.

According to the studies CC is successful at inducing ovulation in 50%-75% of cases, but only 30-40% becomes pregnant. The difference has been attributed to a negative action of clomifen citrate(CC) in the form of prolonged antiestrogenic effects on endometrial receptivity. For avoiding of these negative effects, giving ethinyl estradiol in sufficient dosages may be effective. The purpose of this study is comparing pregnancy rates after IUI in women who use CC alone and those who use CC in combination with ethinyl estradiol

The improved survival rate of extremely low birth weight(ELBW)infants has resulted in new fluid and electrolyte problems that have not been encountered previously,in particular electrolyte imbalance. ELBW infants are especially vulnerable to hypernatremia(serum sodium value >150 mEq/L). Hypernatremia may be due to rapid dehydration or excessive administration of intravenous fluids(IV)that contain sodium. The current treatment modality for hypernatremia is to increase IV fluids above daily requirements.Enteral sterile water feeds(ESWF)are theorized as an endogenous source of fluids that may decrease elevated electrolytes such as sodium and potassium in premature infants. By giving ESWF to decrease elevated electrolytes, there would be less need for large volumes of IVF that contribute to the co-morbidities of prematurity: bronchopulmonary dysplasia (BPD),intraventricular hemorrhage(IVH)and patent ductus arteriosus(PDA). The purpose of this proposed study is to determine whether enteral sterile water feedings is effective in decreasing the incidence, duration and severity of hypernatremia in ELBW infants.

During in vitro fertilisation (IVF) treatment, women receive hormone stimulation with gonadotropins to induce growth of several ovarian follicles. Selecting the optimal dosage of gonadotropin is important to avoid maturation of too few or too many follicles, which may impair the chances of treatment success, lead to treatment cancellation, or serious side effects. Motivated by the lack of standardised procedures to estimate the optimal dosage of gonadotropins, a patient-specific test has been developed to predict the optimal hormone dosage. By measuring internalisation of gonadotropin by the patient's monocytes isolated form the peripheral blood ex vivo, the Gonadotropin Removal Test determines whether a patient needs increased or reduced hormon doses. In this clinical study the investigators compare deviation from optimal outcome at oocyte pick-up day in two patient groups. Optimal outcome of stimulation is defined as 10 oocytes collected in the group of patients matching the inclusion criteria of the study. The control group receives starting hormone dosage assigned by the clinician according to standard clinical procedures. The intervention group receives starting hormone dosage adjusted according to the results of the Gonadotropin Removal Test.
