Active clinical trials for "Infertility"

Intracytoplasmic sperm injection (ICSI) is one of the standard clinical treatments for infertility. ICSI involves the injection of a single sperm into an oocyte with a sharp micropipette. Injecting a sperm with DNA fragmentation (i.e., physical breakage of the DNA double strands) into the oocyte deterministically lowers the IVF fertilization rate [1][2] and increases the miscarriage rate [3][4]. Since the invention of ICSI in 1992, single sperm selection in ICSI has been made manually by embryologists, who select sperm by qualitatively choosing sperm with "good" motility and/or morphology based on their empirical experience. This involves significant subjectivity and inconsistency. We have developed a robotic system to select sperm with low sperm DNA fragmentation. Automated sperm selection also eliminates the subjectivity and inconsistency in manual sperm selection. The system consists of a camera to acquire images of sperm and a software to analyze the images. Embryologists select sperm by observing the same sperm characteristics as in the software criteria (e.g., speed etc.), but the software provides a more accurate and quantitative measure of sperm characteristics, thus ensuring the selected sperm have low DNA fragmentation.

It is expected that 84% natural pregnancy will occur at the end of the first 12 months of sexual intercourse without the use of contraceptive methods.The lack of natural fertility is under the influence of multiple factors. These factors can be summarized as age, past infections, genetic factors, anatomical structural disorders, environmental toxins, occupational exposure, lifestyle and sexually transmitted infections.Severe psychological stress, anxiety and depression are encountered in the diagnosis, treatment method and management of the related process in couples who are faced with the diagnosis of infertility. With the telehealth service that came to the fore in the world in the 1950s, nurses use it in the management of many treatment processes such as infertility treatment, with the roles of managing the information collection process, making decisions with the information they receive, and transmitting information on patients who are far away and need constant follow-up. Assisted reproductive technologies, which are the current treatment method of infertility, have been used effectively for thirty years. Anxiety control is important in the success of treatment in the treatment process, which is both costly and stressful. Providing 24/7 hours of counseling by using telehealth methods contributes to the reduction of this anxiety.

The main objective of this clinical study is to demonstrate the non-inferiority of the semi automated device (DaVitri) developed by Overture Life in the preparation procedures for vitrification of human samples.

To goal of this study is to determine whether laparoscopic resection of colorectal endometriosis results in an increased cumulative live birth rate (CLBR) both spontaneous and after in vitro fertilization (IVF), and better patient reported outcome measures (PROMs) compared to an IVF treatment trajectory.

Intracytoplasmic sperm injection (ICSI) is a procedure performed during in vitro fertilization (IVF) in which a single sperm is injected directly into an oocyte. This procedure was developed for male factor infertility due to its requirement for a very small number of viable sperm. However, its use has expanded and is now recommended for IVF cycles in which preimplantation genetic testing for aneuploidies (PGT-A) is performed on blastocysts. We hypothesize that the ICSI procedure may interfere with the normal meiosis II process that occurs during fertilization, and lead to a higher rate of aneuploid blastocysts. In our study we will randomly assign non-male factor infertility patients to either conventional insemination or ICSI and compare the rate of karyotypically normal embryos in each group.

Infertility, defined as the inability to become pregnant after one year of regular unprotected sexual intercourse. It is estimated that around 20 % of couples suffer from infertility with prevalence rates of infertility differing substantial among countries . Sexual function in females is very complex and is affected by many factors. The prevalence of sexual dysfunction is higher in infertile patients compared to the normal population . Whether sexual dysfunction is the cause or consequence of subfertility is difficult to establish. For instance, sexual dysfunction might result in decreased coital frequency compounding the issue of subfertility due to reduced exposure. On the other hand, the psychological pressure to get pregnant stemming from sex on demand could result in a reduction in enjoyment of sex aggravating sexual dysfunction. Indeed, situational sexual dysfunction and loss of a couple's intimacy may occur as a consequence of timed intercourse where focus for coitus is no longer pleasure but conception .

Two hundred cycles will be enrolled (100 laser-assisted thinning and 100 laser-assisted drillings). They will be compared regarding the implantation and clinical pregnancy rates

The study design is an observational cohort study. Level of serum P4 will be collected on day OR+4 as well as on the day of embryo transfer (ET) either day OR+3 or OR+5.

Background: - The body produces gonadotropin-releasing hormone (GnRH) about every 2 hours. GnRH travels through the bloodstream to the pituitary gland, where it stimulates the gland to produce hormones called gonadotropins. These hormones stimulate the testicles or ovaries. The testicles produce testosterone and develop sperm. The ovaries produce estrogen and prepare for ovulation. Normal estrogen and testosterone levels are required for puberty. Some people, however, have either low levels or total lack of GnRH. This can cause problems with puberty and fertility. Researchers want to study people with low or no GnRH to better understand how it affects puberty and fertility. Objectives: - To study disorders of GnRH production. Eligibility: Adult men and women at least 18 years of age with low or no gonadotropin levels. Adolescents between 14 and 18 years of age with low or no gonadotropin levels. Design: Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. Participants will have tests to look at their hormone levels. Blood samples may be collected after taking different drugs, including insulin and cortisone. A 24-hour urine sample will be collected. Participants will have imaging studies to look at bone and brain development. They will also have ultrasounds of the kidneys, abdomen, and reproductive organs. Tests of smell and hearing will be used to look for abnormalities in these senses.

Human embryonic stem cells (hESCs) are isolated from the early human embryo and have the capability to proliferate indefinitely in culture and to develop into nearly every cell of the human body. hESC are important for studying developmental biology and for cell replacement therapies for the treatment of degenerative human diseases. An additional use for embryonic stem cells would be for the in vitro study of diseases. hESC lines derived from embryos diagnosed as abnormal by PGD testing would afford such models for study. Because embryos tested by PGD and found to be abnormal would only under rare circumstances be transferred to the uterus of a woman (and in most cases would be discarded), the derivation of new hESC lines from these embryos would provide a viable less ethically-objectionable source of cells with which to study the mechanisms of differentiation and developmental biology.
