Filter by:This study aims to see if taking a small sample from the lining of the womb (the 'scratch') before starting in vitro fertilization (IVF) treatment can influence the chance of getting pregnant and having a healthy, term baby. This study also aims to explore why an embryo is not accepted or indeed rejected by the lining of the womb. This will be analysed by carefully looking at the sample taken from the lining of the womb under the microscope and analysing the levels of natural killer (NK) cells. These cells are thought to regulate the implantation process and to be altered in some women with infertility and miscarriage.
The purpose of this randomized controlled clinical trial is to evaluate the effects of clomiphene citrate compared to placebo (substance without active medication) in men who are taking pain medication (opioids) for chronic pain conditions and who have low blood testosterone levels. The condition of men having low testosterone with long-term pain medication (opioid) usage is called opioid-induced androgen deficiency (OPIAD). Low testosterone can be caused by pain medication effects on part of the brain (hypothalamic-pituitary axis) which ultimately result in decreased testosterone production by the testes. Typical symptoms of low testosterone (hypogonadism) may include decreased muscle mass, increased fat, osteoporosis, anemia, erectile dysfunction, delayed ejaculation. In addition, men with low testosterone may experience decreased attention, and decreased libido, fatigue, and depressed mood. Few studies have looked at hormonal changes caused by long-term opioid usage in men. Clomiphene citrate, a selective estrogen receptor modulator (SERM) oral medication which inhibits estrogen effects (feedback) on the brain, has been identified by prior studies to raise testosterone in men with low testosterone (due to reasons other than chronic pain medication). Clomiphene citrate is also known to lead to increased sperm production in men with low testosterone unlike testosterone topical or injection medications. Although clomiphene citrate has been studied in hypogonadal men with beneficial outcomes and minimal side effects, no group has previously studied clomiphene citrate as treatment in patients with OPIAD.
HP-hMG, recombinant FSH (r-hFSH) and a combination of r-hFSH/r-hLH, are commonly used for ovarian stimulation in infertile women undergoing IVF/ICSI treatments. Several publications have compared the effectiveness of these compounds, in terms of clinical outcomes. The aim of our study is to investigate the effects of three different ovarian stimulation protocols (HP-hMG, r-hFSH and r-hFSH/r-hLH), in a pilot prospective observational study, evaluating the effects of recombinant LH and extractive hCG (with LH like activity) on the biological outcome as well as on the clinical outcome. We will use the apoptosis rate of the cumulus cell, usually discarded after oocyte collection, as molecular biomarker to assess the oocyte quality, as biological outcome. The clinical outcome was estimated measuring implantation and ongoing pregnancy rates within and between the three different ovarian stimulation protocols
This is a prospective, multicenter, open-label, comparative and parallel-group study of ovulation induction evaluating tailoring of Recombinant follicle stimulating hormone (FSH) treatment using the Gonal-f® prefilled pen in World Health Organization (WHO) Type 2 anovulatory subjects who have previously failed to conceive with clomifene treatment.
Sperms are prepared by sperm washing techniques before used in assisted reproductive technologies. Most commonly used sperm preparation methods are the swim up and the density gradient. Recent studies shows that the DNA integrity status of the spermatozoa is related to the success in assisted reproduction techniques. Sperm preparation methods may theoretically cause damage to sperm DNA. Therefore it is important to select the optimum method of sperm preparation causing least sperm DNA damage. Aim of our study is to investigate and compare the effect two different sperm preparation techniques on DNA fragmentation.
This is a single-blind, randomized, comparative, phase I study to evaluate the tolerability, safety and pharmacokinetic characteristics of human chorionic gonadotropin between two recombinant hCG products named DA-3803 injection and ovidrel liquid injection, in healthy subjects. The subjects will injected with these two injections at the the 21day-interval of time and their conditions including vital signs, blood, clinical examination will be carefully observed.
Female inability to conceive a child. The purpose of this randomized, two-arm and double blind, double dummy study is to demonstrate that the treatment of a daily dose of 3x10mg dydrogesterone orally is as effective and safe as the daily dose of 3x200 mg micronized progesterone capsules administered intravaginally for the luteal support in patients undergoing IVF. The treatment will start on the day of oocyte retrieval and continue until pregnancy is negative or until week 12 gestation.Patients will be followed after treatment until 30 days after delivery to record any safety and tolerability data of the patient and their newborn(s).
Uterus transplantation, as a possible future treatment for uterine factor infertility, has been developed in animal species during the last decade. The study protocol includes transplantation of the uterus from a live donor (mother, relative, friend) into women with absolute uterine factor infertility (lack of uterus from birth or due to life saving hysterectomy).The recipient will be treated by standard immunosuppression and transfer of embryos (acquired by IVF before surgery) will be attempted when at least 12 months have passed from transplantation. Approval for a case series including up to 10 patients has been acquired.
Male infertility is a multifactorial disease process with a number of potential contributive causes. Considering the majority of male infertility cases are due to deficient sperm production of unknown origin, environmental and nutritional factors must be evaluated. The purpose of this study is to evaluate the effects of 6 months antioxidant dietary complement (Conceptio) on sperm parameters (sperm count, motility and DNA fragmentation) in infertile men with oligoasthenozoospermia.
A novel gonadotropin protocol for ovarian stimulation adds low-dose hCG (50- 200 IU) as a source of LH (luteinizing hormone) in the late follicular phase . This regimen reduces the number of small pre-ovulatory follicles which could reduce the risk of OHSS(ovarian hyper stimulation syndrome). Adequate ovarian hormonal levels , oocyte maturation, avoidance of a premature LH surge, and increased pregnancy rate are the other benefits of this regimen. HCG might also affect endometrial function, stimulate endometrial growth and maturation and enhance the endometrial angiogenesis. These effects could extend the angiogenesis. These results could lengthen the implantation Window. Inhibin A is a heterodimer protein and does not begin to increase until just after the increase in oestradiol in the late follicular phase, suggesting secretion by the dominant follicle. Inhibin A secretion is regulated by LH and is associated with paracrine/autocrine action on oocyte maturation. Moreover, it is related to follicular development and size, serving as a marker of follicular maturation after IVF cycles .However, the role of hCG supplementation during COH (controlled ovarian hyperstimulation)is still a matter of debate and more studies is needed. Thus, the objective of this trial was to investigate whether LH activity in the form of low dose hCG in GnRH (Gonadotropin releasing hormone)antagonist cycles would improve the quality of oocytes, level of inhibin A and endometrial vascularity.
