Fertility is a fundamental function of reproductive health that is under the control of different hormones, cytokines, and growth factors. Transforming growth factor superfamily is a group of cytokines necessary for blastocyst implantation as they regulate endometrial stromal cell proliferation, and promote embryonic adherence to the receptive endometrium. Hyaluronic acid molecule (HA) is a long, unbranched polysaccharide that plays a delicate function in reproduction. Hyaluronic acid regulates gametogenesis, folliculogenesisi, and implantation, thereby was oroposed to improve the rate of successful pregnancy.This study is a prospective clinical trial that includes 80 infertile Iraqi women aged (18-40 years) scheduled for fresh ICSI program. The study sample had been divided into 2 groups based on the type of intervention performed on the day of oocytes retrieval. The Hyaluronic acid group and the control group. For each participant, twice measurement of the serum level of transforming growth factor were done , the first measure was done on day of oocytes retrieval, while the second measure was performed on day of embryo transfer. A comparative statistic was made to examine the effect of hyaluronic acid intrauterine wash on the serum level of transforming growth factor and pregnancy rate.Hyaluronic acid intrauterine wash exerts a significant reduction in transforming growth factor serum level, and a significant improvement in the pregnancy outcome compared to the control group.
Activin is a member of the transforming growth factor-beta superfamily and is a polypeptide growth factor. Activin regulates follicle growth, gonadotropin responsiveness, steroidogenesis, oocyte maturation, ovulation, and corpus luteum function in the ovary via a local autocrine/paracrine effect. Activin measurement A level in serum and follicular fluid during the preovulatory stage in PCOS women undergoing an IVF/ICSI cycle to predict fertilization capacity earlier Fifty infertile couples, 25 with PCOS and 25 without PCOS, who attended Al Nahrain University in Baghdad, Iraq's High Institute of Infertility Diagnosis and Assisted Reproductive Technologies. The females that participated were between the ages of 18 and 40. On the day of oocyte retrieval, the level of Activin A in serum and follicular fluid was measured. Activin A levels in PCOS women's serum (activin A=1274 77.9) and follicular fluid (activin A =1038 50.3) compared to non-PCOS women's serum (activin A=453 25.74) and follicular fluid (Activin A=450 23.73). The study shows no correlation between activin A hormone with oocytes characteristics and fertilization rate in PCOS women with a significant increase of activin A hormone in the serum and FF of PCOS women compared to non PCOS women. Activin A level can predict a diagnosis of PCOS in addition to positive predictive pregnancy but not indicator of fertilization capacity in PCOS women.
