Filter by:Infertility-the inability to conceive despite one year of properly timed unprotected intercourse-is a common problem. Of all types of male factor infertility, non-obstructive azoospermia may be the most difficult for couples. Importantly, patients with non-obstructive azoospermia are asked to make difficult decisions in terms of reproductive choice; surgical attempts at identifying sperm (microdissection testicular sperm extraction) are often offered to these patients without a guarantee of being able to identify sperm. New methodologies in terms of evaluation of azoospermic males PRIOR to the couple embarking upon IVF are needed urgently. The other potential benefit of non-invasive determination of testis function and spermatogenesis would be the potential targeting of sperm extraction procedures. We hypothesize that quantitative MRI employing advanced functional metrics will be sensitive to functional and metabolic differences between subsets of azoospermic cases and will improve upon current characterization of patients with this condition. Moreover, it is believed that these techniques will provide complementary information, such that they may be combined in a synergistic fashion for targeted extraction methodologies.
Identify, by Lipidomics approaches, biochemical markers of fertility / infertility in sperm and seminal plasma linking the success or failure of the artificial insemination (IUI)
Many chemotherapy and radiation-containing regimens for cancer or prior to bone marrow transplantation can cause sterility in children and young adults. In addition, some human disease conditions (e.g., Klinefelter's) are associated with infertility. Semen cryopreservation is available as a fertility-preserving option for post pubertal boys and adult men, but many do not take advantage of this option due in part to lack of information, illness, and/or time constraints relative to their treatment plan. Currently, no fertility-preserving options are available for prepubescent boys who are not yet producing sperm. The primary objective of the proposed study is to 1) Optimize techniques for cryopreserving testicular tissue, 2) Assess malignant contamination in testicular tissues and 3) develop methods to enrich spermatogonial stem cells and remove malignant contamination from testicular tissue. In addition, this study will process and cryopreserve tissue and/or cells for participating patients as a resource for future elective procedures to attempt fertility restoration.
The primary objective of this study is to explore feasibility of testis functionality assessment and testis imaging obtained from Positron Emissions Tomography (PET) /Magnetic Resonance Imagine (MRI). Using advanced MRI metrics, investigators will study the three-dimensional structure of normal testis, the levels of specific elements and compounds in the tissues (which can only be found via these imaging techniques), and the directionality (and alterations in directionality) of tissue structure. Investigators hope to develop hypothesis that will in turn suggest bio-markers to be explored in subsequent clinical trials.
Since the development in the last few years of the bipolar energy in the surgery by hysteroscopy, the hysteroscopic treatment of the submucosal uterine myoma can be performed by use of either monopolar or bipolar current. It seems that the use of the bipolar energy decreases the rate of adhesions but prospective data on the adhesion rate and fertility after the use of bipolar energy during the surgery are poor, and there is currently no recommendation as to the choice of technique to use. The main purpose of this study is to compare the rate of uterine adhesions six weeks after the surgical hysteroscopic treatment of uterine submucosal myoma, by using monopolar or bipolar energy. The pregnancy and spontaneous miscarriage rate will also be evaluated.
Human immunodeficiency virus (HIV) infection has now become a treatable disease and many infected individuals are interested in having a family. Couples in which the man is infected but the woman is HIV-negative (hereafter referred to as HIV-discordant) require medical intervention during procreation to prevent HIV transmission to the female and her child. The current view is that reducing the number of infections involving unprotected intercourse in HIV-discordant couples is a public health issue in the U.S. The safest methods for HIV-discordant couples are insemination using a sperm donor, adoption and remaining childless. However, some couples strongly desire a biologically related child. Fertility clinics in the United States have been resistant to treating HIV-discordant couples, offering only expensive, invasive techniques. This reduces access to care, leading to couples choosing unprotected intercourse to conceive a child. Pre-exposure prophylaxis (PrEP) is a treatment taken by the woman before having unprotected intercourse with an infected man. Truvada has been approved by the Food and Drug Administration (FDA) to reduce the risk of HIV-discordant couples and the Centers for Disease Control and prevention (CDC) has recommended that serodiscordant patients who wish to have a child be counseled on the availability of PrEP. When risks of transmission are minimized, including undetectable HIV in blood and use of PrEP, unprotected intercourse during the fertile period is likely to be a safe option for conceiving a child. The investigators propose to enroll HIV-discordant couples who have been counseled on the safer alternatives of donor insemination, adoption and remaining childless; have been offered referral to a clinic offering sperm washing with insemination or in vitro fertilization (IVF); have been apprised of the risks of using PrEP and one timed intercourse per cycle; and decide to proceed with this method. Couples will be from the population of HIV-discordant patients with a minimal risk of disease transmission as described above. After evaluation for normal fertility and low potential for disease transmission, the couple will receive instruction on timing of the most fertile day of the cycle, and the woman will be given a prescription for the PrEP medication. The woman and any offspring will be followed for 6 months using blood tests to check for evidence of HIV infection.
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).
This is a prospective randomized control, crossover trial to determine if supraovulation with clomiphene citrate and intrauterine insemination is more efficacious than expectant management in women with stage III or IV endometriosis who have recently undergone operative laparoscopy.
To compare the effectiveness of single step culture media and continuous uninterrupted culture media on blastulation rate
Patients & Methods: Eighty infertile women were randomly categorized into: Group EF (n=40) had EF after oocyte retrieval and Control group (n=40) did not have EF. All women were subjecte to the standard down-regulation regimen followed by controlled ovarian hyper stimulation . Oocytes were retrieved 34-36 h after hCG administration and aspirated FF was collected and centrifuged at 600 rpm for 10 min and 5-ml sample of supernatant was obtained for ELISA estimation of tumor necrosis factor-α (TNF-α), granulocyte colony-stimulating factor (G-CSF), leptin and anti-Mullerian Hormone (AMH) levels in both groups. The remaining amount was used for EF in EF group and was discarded in control group. Pregnancy was diagnosed by measurement of β-HCG level and confirmed by transvaginal sonography as clinical pregnancy
