Active clinical trials for "Infertility"

Infertility is defined as the inability of a couple to achieve pregnancy over an average period of one year (in women under 35 years of age) or 6 months (in women above 35 years of age) of unprotected sexual intercourse. Infertility can be due to female, male reasons or both. It can be either primary or secondary. Thyroid dysfunction and autoimmune thyroiditis are known adverse risk factors for pregnancy as well as fertility, regardless of the presence of disease in women of reproductive age. In particular, hypothyroid women are at an increased risk of menstrual disorders and infertility because of altered peripheral estrogen metabolism, hyperprolactinaemia and abnormal release of gonadotropin-releasing hormone. The prevalence of subclinical hypothyroidism characterized by aberrant high serum thyroid-stimulating hormone (TSH) levels with normal free thyroxin (FT4) levels in infertile women are reported to be approximately 20% and it is a primary cause of subfertility. Indeed, average TSH levels in infertile women were reportedly higher than those in normal fertile women. And elevated serum TSH levels were associated with diminished ovarian reserve in infertile patients. Moreover, although levothyroxine replacement therapy for subclinical hypothyroidism in infertile patients remains debatable, thyroxin supplementation may improve fertility to successful pregnancy. This data suggests that hypothyroidism is strongly correlated with infertility (Velkeniers et al., 2013). On the other hand, female fecundity decreases with increasing age, primarily because of decreased ovarian function. Anti-mullerian hormone (AMH) is a dimeric glycoprotein belonging to the transforming growth factor-beta (TGF-B) super family, which act on tissue growth and differentiation. It is produced by the granulosa cells from pre-antral and small antral follicles. Ovarian research after oophorectomy showed that serum AMH levels were closely correlated with the number of primordial follicles; therefore, AMH is a suitable biomarker of ovarian age in women of reproductive age. Expectedly, ovarian function may be affected by impaired thyroid function, although this association has not been elucidated. In this study, we will evaluate the relationship between thyroid function and AMH levels by comparing them in infertile patients and healthy fertile women.

This study is designed to assess the accuracy of Body Mass Index ,Waist Circumference ,Waist Hip Ratio or Waist Height Ratio as a predictor of ovarian response in women undergoing ICSI.

This is a controlled preminary trial intended to increase the implantation rate of IVF cycles, by using more than one known procedure, endometrial scratching, evaluating the status of the adhesive factors as αVβ3 integrin, L-selectin ligand MECA-79, E-cadherin and ICAM-1, as a determinant for intervention by G-CSF, according to a score that can be done on a small sample obtained during scratching, then give G-CSF for the scores less than 4 intrauterine and subcutaneously.

Patient care in Medically Assisted Procreation (MAP) requires a close and regular monitoring of the evolution of the estradiol rate. This monitoring allows the dose and duration of treatment to be accurately adjusted for each woman (every 24 or 48 hours) up to 10 to 15 days of treatment with gonadotrophins. Oestradiol (E2) is secreted by the growing ovarian follicles and reflects their growth and maturity. Its plasma dosage makes it possible to monitor the ovarian response to stimulation. This monitoring involves several constraints amongst which disruption of work life, stress, fatigue that can alter the response to treatment

This study will be conducted at the In vitro fertilization Unit at Ain Shams University Maternity Hospital. Women will be recruited from the In vitro fertilization Unit who will fulfill the inclusion criteria. They will be counseled to be included into the study The study will assess Role of Ratio of Progesterone to Number of Follicles as a Prognostic Tool for Intracytoplasmic Sperm Injection outcome.

Infertile couples who come for evaluation and treatment in IVF unit could be under psychological stress. Many authors in the past suggested that stress itself is one of the factors that directly influence fecundability rate. In couples treated in IVF unit, the investigators aim to measure chronic stress by measuring hair cortisol level (as a marker for chronic cortisol release) and by filling different questionnaires.

Comparing the reproductive outcomes of intracytoplasmic sperm injection (ICSI) cycles in women at risk of ovarian hyperstimulation syndrome (OHSS) subjected to gonadotropin releasing hormone (GnRH) antagonist protocol followed by trigger with concomitant GnRH agonist (GnRHa) and low-dose human chorionic gonadotropin (HCG) administration (dual trigger), GnRHa trigger with single luteal low-dose HCG or GnRHa trigger with multiple luteal low-doses HCG

The aim of this study is observing the relation between serum Vitamin D levels and morphokinesis of time lapse monitored Day 5 embryo in between 18 and 38 years age women undergoing controlled ovarian hyperstimulation (COH) because of unexplained or tubal factor infertility. Individuals will be divided into 2 groups according to serum vitamin D levels as normal or low , and the influence of those levels in morphokinetic parameters of embryos will be identified.

The purpose of this clinical trial is to collect imaging data on embryos followed to blastocyst stage (Day 5-6) for ongoing development and validation of the Eeva System.

Many IVF clinics offer testing for immune cells in the blood and endometrium as it has been suggested that abnormal levels of these cells can affect fertility or the chance of an IVF cycle working. However, routinely offering these tests remains highly controversial as the scientific evidence behind the tests is not of a high quality. The PIP Study aims to find out how a woman's blood and endometrial immune cells affect the likelihood of an IVF cycle working and whether or not they are different in women with subfertility and implantation failure. This feasibility study aims to find out if it is possible to enrol enough women into the research study. If this is successful, the investigators will then go on to recruit a larger group of women into the main PIP study to enable them to investigate the impact of immune profiling on IVF success in more detail.
