Active clinical trials for "Infertility"

Presently spermatozoa for ICSI are selected based on morphology and motion, without determining if acrosome reaction (AR) had occurred during sperm preparation or not. Although not critical if the sperm is injected into the ooplasm, the occurrence of AR might might be an indicator of better spermatozoon quality and implantation potential, especially in severe OTA cases. It is impossible with conventional plain optic microscopy used in IVF units to determine in vivo (without fixation) if AR has occurred, and as a result spermatozoa are injected randomly. It is readily possible to distinguish AR+ from AR- spermatozoa using polarized light microscopy due to different bifriengance. In this study the investigators seek to determine, by a prospective RCT, if selecting only acrosome reacted spermatozoa, in severe OTA cases, will improve the outcome of ICSI and the entire IVF process.

As an essential step of the infertile work-up, hysterosalpingogram (HSG) has some advantages including the lack of need for anesthesia, a non-invasive procedure with less cost and relative easy to put into practice. However, it would be failed to detect the extra-tubal and peritoneal pathology and would be also difficult to distinguish the obstruction caused by the spasm of intramural segment. Obviously, imaging quality plays a key role in diagnostic accuracy of the HSG, studies had taken four roentgenograms and combined with the fluoroscopy were reported a higher sensitivity and specificity than those only taken two images in the examination. And hybridized radiography with CT or MRI system may provide the good-quality of the HSG. It is also reported that the sonosalpingography (SSG), which detect the tubal patency in real time, can show pelvic pathologies better than HSG. However, no parallel study was designed to verify the hypothesis that combined the fluoroscopy and taken more images can improving the diagnostic quality of the HSG. The aim of this study is to evaluate whether the accuracy of HSG can be improved by real-time evaluating under the fluoroscopy.

This study will be a 6-month intervention that is examining how different dietary approached may be useful for women with Polycystic Ovarian Syndrome (PCOS) who are attempting pregnancy, particularly by measuring changes in weight. Participants will be randomly assigned to following one of two dietary approaches for weight loss: 1) a low-calorie approach to weight loss (reducing caloric intake by approximately 500 calories per day) or 2) a low-fat, low-glycemic index vegan diet. A vegan diet is one that does not contain any animal products (no meat, fish, poultry, eggs, or dairy) but emphasizes plant-based foods, such as fruits, vegetables, whole grains, and legumes/beans. In addition, this diet will be low-glycemic index, which means the consumer will be asked to favor foods that don't cause a quick rise in blood sugar (for example, favoring oatmeal over cornflakes for breakfast). Participants will receive counseling and supporting materials on the dietary approach the participants are assigned to follow. Both diets are safe and have shown to be effective ways to assist with achieving a healthy weight. The investigators hypothesize that both groups will see improvements in weight and fertility with possible greater improvements seen among participants in the vegan group.

The investigators will use a thin catheter for HSG and apply pressure on the cervix with the vaginal speculum to prevent leakage of the dye during injection to study the uterine cavity and fallopian tubes and reduce the pain as compared to a standard metal cannula.

The purpose of this randomized trial is to test the effectiveness of screening and brief intervention for risk drinking by nonpregnant women with specific medical problems exacerbated by excessive alcohol consumption. The medical problems are female factor infertility, hypertension, diabetes, and osteoporosis, conditions that are costly to treat and difficult to manage. Just as pregnant women are thought to be highly motivated to modify their alcohol consumption, so women with specific medical problems worsened by alcohol intake are an appropriate group to receive a brief intervention.

To compare the effectiveness of vaginal isonicotinic acid hydrazide with placebo in minimizing the pain experienced by primarily infertile patients during diagnostic office hysteroscopy and to assess the ease of insertion of hysteroscope as reported by the hysteroscopist.

Saline infusion sonography (SIS) and hysteroscopy are commonly employed methods for uterine cavity evaluation. While hysteroscopy is regarded as the gold standard for diagnosis of intra-uterine pathology, it is not often used as an initial screening tool because of provider concerns about in-office tolerability, operating room costs, and use of anesthesia. The investigators aim to compare SIS and office hysteroscopy with respect to patient and provider satisfaction. Additionally, the investigators aim to assess the capability of office-based hysteroscopy to manage intra-uterine pathology at the time of diagnosis and reduce delays and supernumerary procedures.

Pilot study to evaluate the effect of the strain Lactobacillus PS11610 on the microbiota of the female and male genital tract in couples with fertility problems. Couples who have started treatment for artificial insemination or who are on the waiting list for an invitro fertilization treatment will be invited to participate. The estimated duration of the study will be 7 and a half months.

The study targets to evaluate the role of estimation of plasma expression levels of gene of microRNAs 203 and 210 in helping to diagnose and grade endometriosis. The study included women with unexplained infertility and clinical picture suggestive of presence of endometriosis were divided randomly into two groups: Control and study groups. All patients underwent exploratory laparotomy for diagnosis and grading of endometriosis if present. Patients of study group gave blood samples for estimation of plasma expression levels of microRNA 203 and 210 using qRT-PCR procedure.

The main purpose of this study is to compare the number of oocytes retrieved after using transdermal testosterone gel 10 mg per day or Dehydroepiandrosterone (DHEA) 75mg per day for 6-8 weeks as pre-treatment for poor ovarian responders undergoing in-vitro fertilization (IVF).
