Filter by:This study will add: Finding out an association between Protein S activity and unexplained female infertility. Aim: Study hypothesis: In women with unexplained infertility protein S activity may be low. Study question: In women with unexplained infertility does protein S activity low?. This study aims to assess the activity of protein S activity in women with unexplained infertility. Objectives: The main objective of this study is: To determine the prevalence of Protein S activity with unexplained female infertility and to compare its prevalence in fertile women among women attending outpatient clinics at Ain Shams University Maternity Hospital.
Polycystic ovarian syndrome (PCOS) is a heterogeneous, multifaceted and complex disorder characterized by insulin resistance (IR), hyperinsulinemia, and hyperandrogenism leading ovarian disfunction and infertility. Given the central pathogenic role of IR in the endocrine, reproductive, and metabolic disturbances of PCOS, several pharmacological and non-pharmacological approaches have been proposed to counteract the hyper insulinemic IR typical of the syndrome. Two Inositol stereoisomers, Myo-Inositol (MI) and D-chiro-inositol (DCI), captured the attention of researchers for their insulin-sensitizing actions, which configure them as proper candidates for the treatment of PCOS. Very few studies reported on spontaneous clinical pregnancy rates, none were powered for this outcome, and none reported on the clinically relevant outcome of live birth. Therefore, data about clinical pregnancy rate, live birth rate, and miscarriage rate comparing inositols with placebo are limited. Conversely, about infertility and assisted reproduction techniques (ART), improvements have been reported in PCOS women who underwent fertility treatment using inositol in different forms, combinations or doses. This data, considering the different tissue-specific ratios (i.e., 100:1 in the ovary) and the different physiological roles of inositol stereoisomers, suggest that DCI supplementation alone might not be the optimal or appropriate approach for improving IVF outcomes in PCOS patients, and drawn attention to the importance of MI and DCI supplementation in a physiological ratio in order to restore normal ovary functionality. Indeed, the combination of MI and DCI, at a more physiological ratio of 40:1, was able to more quickly restore to normal the hormonal and metabolic parameters in PCOS women than MI treatment alone or DCI treatment alone, improving the endocrine profile and IR of women with PCOS. Nevertheless, regarding infertility the primary outcomes that should be considered are clinical pregnancy rate, miscarriage rate and live birth rate. Although many studies showed improved hormonal and metabolic profile and improved ovulation rate and higher quality and number of oocyte retrieved in ART in PCOS women after inositols administration, data about clinical pregnancy rate, live birth rate, and miscarriage rate are limited with several concerns regarding interpretation of the studies.
Brief Summary: LM001 is a recombinant human Follicle Stimulating Hormone (r-hFSH) Injection, which is proposed for Assisted Reproductive Technology (ART). This is a randomized, open-label, two-period, two-crossover study to evaluate the safety and pharmacokinetics of recombinant human follicle stimulating hormone injection (LM001), compared with Gonal-F®, both given subcutaneously.
Our findings will provide preliminary clinical evidence to suggest the new experimental treatment approaches, toward female factor infertility treatment with pentoxyfylline.
Agonist triggering in controlled ovarian stimulation protocols is being used during last years (among high responder patients to avoid OHSS). Indeed, agonist triggering is more physiologic than HCG triggering. Investigators propose to compare the effectiveness of both types of trigger among three different subsets of patients: 1. Poor responders. 2. Normo-responders 3. High responders Comparing both the number and the quality of achieved oocytes.
Anti Mullerian hormone (AMH) is gaining place as ovarian marker, chiefly in infertility assistance. Investigators explored its correlation with oocytes retrieval after long GnRH agonist protocol for stimulation, in younger and older infertile population. Methods: This prospective analysis compiled data of 66 females, receiving ICSI treatment from April 2016 to October 2017. Serum FSH, LH, Estadiol, AMH and antral follicle count were assessed. Outcomes were measured as good (5 to 19 oocytes) and bad responders.
The aim of this study is to prospectively examine the relationship of the uterine junctional zone thickness, evaluated by ultrasonography and In Vitro Fertilization (IVF) treatment outcome. The study hypothesis is that the uterine junctional zones of women who did not achieve pregnancy will be thicker than those of the women who do achieve pregnancy
The first In-Vitro Fertilization cycles were performed in natural unstimulated cycles. Today gonadotrophins are administered to induce multiple follicular development and controlled ovarian hyperstimulation. During ovarian stimulation gonadotrophin-releasing hormone analogues are co-administered in order to prevent premature luteinizing hormone surges. Premature luteinizing hormone surges are observed in about 20% of stimulated cycles without using gonadotrophin-releasing hormone analogues . Avoiding the adverse effects of elevated luteinizing hormone levels, first gonadotrophin-releasing hormone agonist analogues were used to supplement the gonadotrophin stimulation. The continuous administration of gonadotrophin-releasing hormone agonists causes gonadotrophin suppression through down-regulation and desensitization of the gonadotrophin-releasing hormone receptors in the pituitary gland after an initial short period of gonadotrophin hypersecretion . Gonadotrophin-releasing hormone antagonists (cetrorelix and ganirelix) cause immediate and rapid gonadotrophin suppression by competitive antagonism of the gonadotrophin-releasing hormone receptor in the pituitary without an initial period of gonadotrophin hypersecretion. Several advantageous effects of cetrorelix were established , and these effects seemed to be independent from the type of antagonist used for luteinizing hormone-suppression.The quality of oocytes and developing preembryos is one of the most relevant factors determining the success of an In-Vitro Fertilization treatment. As ovarian stimulation protocol is one of the eligible factors during an In-Vitro Fertilization treatment, its embryo quality influencing effects are necessary to know.
This will be a prospective, randomized (1:1 ratio) clinical trial for non-male factor infertility in advanced maternal age with or without intracytoplasmic sperm injection(ICSI). Qualified 1422 patients are randomized into either of two groups: group A will undergo conventional in-vitro fertilization(IVF)(711 cases), Group B will undergo intracytoplasmic sperm injection (ICSI) (711 cases). All participants will receive the same protocol for ovarian stimulation and standardized luteal phase support. The target population will be patients with non-male factor infertility aged ≥38years with FSH ≤15. Women with other reasons of infertility (eg. anovulation, endometriosis, and premature ovarian failure) are excluded. The randomization will take place before controlled ovarian stimulation by a computer randomization system. The accumulated live birth rate , pregnancy complications will be followed up by checking medical records and telephone calls.
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.
