A Novel Concept of Fundus-Ovary-Salpinx-Para-Aorta Implantation Promoting Unit during Human Embryo Implantation. By Hiroshi Fujiwara, Yoshihiko Araki, Shigeru Saito, Kazuhiko Imakawa, Satoru Kyo, Minoru Shigeta, Masahide Shiotani, Akihito Horie and Takahide Mori. Human embryo implantation is mainly regulated by the endocrine system. Since the ovary, fallopian tube, and fundus can directly communicate through the mesosalpinx and ovarian ligament, the local concentration of progesterone in the pathway of the developing embryo is considered to be higher than in systemic blood circulation. The immune system promotes embryo implantation by stimulating progesterone production of the ovary and by inducing endometrial differentiation. The recognition of the developing embryo in the fallopian tube by the immune system is achieved through the para-aortic lymph nodes. On the basis of the above evidence, the autologous immune cells activated in vitro were demonstrated to improve clinical pregnancy rates in ...

RESULTS: During the 426 cycles, clinical pregnancy rate was 49.77% and embryo implantation rate was 27.20%. Differences in estradiol and progesterone levels on the day of endometrial transformation and before transplantation between pregnant and non-pregnant groups were not statistically significant. Furthermore, embryo implantation rate and clinical pregnancy rate among different levels of estradiol patients was not statistical different. On the day before transplantation, serum estradiol level decreased in 98.36% of patients. Differences in implantation rate and clinical pregnancy rate among patients with different extents of decrease in estradiol and different progesterone levels on the day before transplantation were statistically significant ( ...
Uterine and Serum Glycodelin Concentration in Recurrent Implantation Failure Versus Normal Fertile Women on Implantation Window. Robabeh Taheripanah1 , Marzieh Zamaniyan2* , Shahrzad Akhoondzadeh1 , Anahita Taheripanah3 , Narges Malih4. Abstract Objectives: Glycodelin is a factor which regulates immunological activity and is required in implantation window. The present study was conducted to compare glycodelin concentrations in blood and uterine flushing samples from women with in vitro fertilization (IVF) failure and fertile controls. Materials and Methods: This was a prospective clinical trial including 20 women with IVF failure and 19 fertile participants. Both groups initially filled a special questionnaire including their demographic profile and prior failed IVF attempts. Then samples of uterine flushing and blood samples were taken to measure glycodelin concentrations. Results: There were significant differences between mean glycodelin concentrations in the case and control groups, both in ...

During the development of multicellular organisms, integrins act through integrin-associated molecules to regulate essential aspects of cell-cell and cell-matrix adhesion, cell polarity and cell survival. On p. 2913, Reinhard Fässler and co-authors report that the integrin-associated protein PINCH1 regulates all four of these processes during the peri-implantation stage of mouse development. PINCH1 interacts with integrin cytoplasmic tails at focal adhesions via integrin-linked kinase (ILK). The authors show that, like β1-integrin- and Ilk-deficient mice, mouse embryos carrying a disrupted PINCH1 gene arrest at the peri-implantation stage. To pinpoint this phenotype, the authors examined embryoid bodies (EBs), an experimental model for this stage of development. Although PINCH1-null EBs show many of the same defects as β1-integrin- and Ilk-mutant EBs (including abnormal epiblast polarity and detachment of cells from matrix), they also exhibit abnormal cell-cell adhesion and increased ...

If youve experienced Unexplained Implantation Failure, you may be searching for information and treatment options. Dr. Jay Schinfeld of Abington Reproductive Medicine explains the diagnosis and how it is treated.
One of the interventions which has been recently proposed to enhance endometrial receptivity is the technique called endometrial scratching. This is an extremely easy and inexpensive intervention , in which we injuring the uterine lining in a very controlled fashion. This might sound very counter-intuitive - why would one want to actually inflict damage on the endometrium ? Conceptually, this is like the old-fashioned D&C which gynecologists used to use in the past to " treat " unexplained infertility, but its much less invasive. Instead of scraping the uterine lining ( as we do in a D&C), in a scratch procedure we just introduce a file plastic catheter into the uterus, in order to remove a small strip of the uterine lining. ( The additional benefit this procedure offers is that it allows us to map the cervical canal , and since its very similar to a dummy embryo transfer, it makes the actual ET much easier ...
embryo hatching.. Standard IVF protocols include culturing of embryos within the laboratory for three days, followed by transfer of cleavage stage embryos (6 to 8 cells), on Day 3, to the uterine cavity. Following transfer, the embryos must continue to progress to the blastocyst stage, shed the ZP, and embed into the uterine wall. In 1989 Cohen and his co-investigators observed a higher implantation rate in patients undergoing IVF, who had the ZP of their embryos mechanically opened. They therefore hypothesized that artificially creating a gap in the ZP might serve to facilitate embryo hatching and implantation. Microscopic manipulation of the ZP, in order to augment hatching and implantation, subsequently became known as "assisted hatching". Prospective randomized clinical studies have been performed in order to evaluate the effectiveness of assisted hatching. Several studies report a significant increase in embryo implantation and clinical pregnancy rates, in select groups of patients whose ...
But, regardless of how you feel about the womans choices, what do you think of the doctors choices? Its been said that the doctor implanted all eight embryos into the California moms uterus and all eight took. Other people are saying (theorizing) that fewer embryos were implanted but they divided. While that last thought is true, the idea that only four were implanted and *all* four divided is just on the side of ludicrous. From what Ive been reading, the division itself is rare - but for this woman to have four divide, those are odds worth buying a lottery ticket for. ...

rat trophinin protein: required for early embryo implantation during development, expressed in the subventricular zone and rostral migratory stream of the adult brain, but not in the brain of embryos and early postnatal animals; may play role in adult neurogenesis
It is really amazing what our world has come to, and what we are able to do and what we will be able to do in the near future. Although all of this has also brought upon many ethical and religious concerns for many people, but especially us Catholics.. Regarding genetic modification, it has recently become possible to let embryos grow outside of the human body for up to seven days, by which time, only the most vigorous survive. This reduces the number of embryos implanted and increases the number of successful implantations, while also reducing the number of multiple pregnancies. Most embryos, conceived in in-vitro fertilization clinics eventually die. If they are not implanted, they are either "donated" for research, in which case they are killed, or they are kept in cold storage in very low temperatures after which most are disposed of, or eventually die.. Not infrequently, early in pregnancy, some of these embryos are killed by injection of potassium chloride into the embryos heart. This ...
I have seen a lot of advances in the field of IVF since I first started doing it almost 30 years ago. The art and science have improved immensely, but I have come to realise that IVF is not just a matter of eggs, sperm and embryos. It takes two factors for a successful pregnancy - healthy embryos and a healthy implantation - and adequate preparation of a couple ahead of treatment is vital in order to optimise the outcome.. Our integrated approach to IVF at the Zita West Fertility Clinic involves looking at every aspect of a couples lives, including preparation of the mind, body and spirit, stress levels and micronutrition, and diet is a huge element of that. It takes about three months for eggs and sperm to develop properly and ensuring that they develop under optimum conditions improves the quality of the eggs, the sperm and, subsequently, the embryos. Healthy eggs and sperm equate to healthy embryos.. One of the greatest obstacles to successful implantation of the embryos and the reason why ...

The embryo implantation rate in assisted reproduction procedures is 20%, which leads to a low clinical pregnancy rate (35%), and even lower live birth rate (25%), per cycle started. Low embryo quality, poor endometrial receptivity, difficulties during the blastocyst hatching process are frequently denoted as the main reasons for the low implantation rate in humans.. The artificial rupture or thinning of the zona pellucida before embryo transfer-assisted hatching (AH)-has been proposed to foster spontaneous hatching and improve embryo implantation rates. Despite great effort, the clinical relevance of AH remains controversial and elusive.. There is a great importance of AH during frozen embryo cycles. Due to previous studies there is no precise answer about the value of AH performed on cryopreserved-thawed embryos. As far as is known, there is no clinical data to indicate the effects of AH on vitrified-warmed embryo transfer.. The objective of this prospective study is to assess the possible ...

RESULTS: In this study, we have applied a genome-wide transcript-level changes approach using oligo microarrays representing 37,600 genes to define the transcriptomic profile of RIF patients in comparison to fertile controls.The differentially-expressed genes (DEGs) that met the criteria , log2(Fold Change) , (LFC)≥1 and adjusted p-value≤0.05 were accepted as statistically significant DEGs. The resulting 641 DEGs that met the criteria were then used for further selection with a feature selection wrapper algorithm that helps in identifying aspects the most relevant to the distinction between patients and controls. Feature selection was performed 100 times and DEGs that were chosen in all runs were accepted to be relevant DEGs. Functional enrichment analysis was carried out with 93 DEGs that were accepted as relevant. The BIOCARTA pathway "RAC1 cell motility signaling pathway" as well as related pathways were found to be enriched ...
Dr. Saleh, Eighteen months ago, I was diagnosed with endometriosis when my doctor found 2 chocolate cysts on ultrasound. At the time, he recommended against surgery given my age (Im now 39) my lack of pain, and his concern that it could reduce my ovarian reserve. Since then I have had what I believe to be multiple implantation failures but no successful pregnancies (all natural cycles). I have read that implantation failure is more common in women with endometriosis, but I am unclear
Human chorionic gonadotropin (HCG) injections can enhance embryo implantation before the embryo is transferred into the uterus. Hcg booster shot after embryo transfer is not necessary because HCG shots before embryo transfer are adequate. Progesterone is often given after embryo transfer to support and sustain a pregnancy. Human chorionic gonadotropin (HCG) injections are mainly given in women who undergo in-vitro fertilization (IVF) procedure. Human chorionic gonadotropin (HCG) is a hormone used widely in assisted reproductive treatments (ART) to induce ovulation. Assisted reproductive treatments are ways or methods to treat infertility and to make it possible for a couple to conceive. The definition of infertility is when a couple is unable to conceive despite regular and unprotected sexual intercourse for a one-year duration.. Infertility is a common condition. In the United States, 15% of couples are unable to conceive due to infertility. Infertility can affect the male partner, the female ...
Using single-cell sequencing and an in vitro culture system, researchers followed transcriptomic and epigenomic features over time in three main embryonic cell lineages.
The molecular regulation of mammalian peri-implantation development is complex and difficult to study in vivo. We successfully cultured hamster blastocysts through hatching and peri-attachment stages, using a chemically defined medium, HECM-2h. Using this system, we showed that a species-specific, embryonic cysteine-like protease is involved in blastocyst hatching and that the process is modulated by growth factors. In particular, heparin binding-epidermal growth factor (HB-EGF) or leukemia inhibitory factor (LIF) enhance blastocyst hatching, and the former also improves attachment and trophoblast outgrowth. We observed interesting changing patterns of expression of mRNA and/or immunoreactive protein for EGF, HB-EGF, LIF and transforming growth factor-beta (TGF-beta) in the embryo and/or endometrial tissue, during peri-implantation development. Together, it appears that hamster blastocyst hatching, attachment and trophoblast outgrowth are regulated by autocrine and/or paracrine growth factors, ...
A team of researchers affiliated with multiple institutions in China has used single-cell sequencing to learn more about the human embryo during implantation in the uterus. In their paper published in the journal Nature, the group describes sequencing thousands of human embryo cells from before, during and after implantation, and what they learned from it.. To learn more about what happens during the implantation process, the researchers fertilized 65 human eggs and allowed them to grow in an in vitro culture system. This allowed them to study thousands of cells before, during and after they started the implantation process.. The researchers suggest their work created a path towards better understanding the underlying basis of an array of pregnancy disorders, including recurrent implantation failure, unexplained sporadic and recurrent pregnancy loss and diseases of abnormal placentation.. ...

A sequential study was made of non-delayed and of experimentally delayed rat blastocysts. Alterations in shape, axis lengths and area of non-delayed blastocysts first appeared on the afternoon of Day 5 of pregnancy. Similar changes were observed in delayed blastocysts beginning 12 hr after the simultaneous administration of oestrone and progesterone. In both cases implantation occurred within the subsequent 24 hr. In contrast, delayed blastocysts maintained only with progesterone were markedly larger than normal but failed to demonstrate typical pre-implantation changes or to implant. Therefore it was concluded that changes necessary for and indicative of impending implantation are induced by the synergistic action of oestrone and progesterone on the blastocyst.. Blastocysts from non-delayed and delayed, oestrone-treated animals were consistently free of their zonae pellucidae at least 18 hr prior to implantation-6 hr after pre-implantation changes were initially noted. Progesterone, although it ...

The Endometrial Receptivity Array (ERA) test has been found to be very accurate in determining the implantation window so it reduces the chances of IVF failure.
Evidence from an abundant number of studies suggests that human female reproductive functions have become impaired over the past half century and that there might be a relationship between endocrine disrupting chemicals (EDCs) and reduced fertility. It is, however, not known by what mechanisms EDCs affect different reproductive functions such as endometrial receptivity, embryo implantation and placentation.. The endometrium is continuously changing its morphological and functional properties, responding to cyclic changes of oestrogen and progesterone levels during the menstrual cycle. These changes include monthly preparation for embryo implantation through changed endometrial angiogenic activity and consequent changes in endometrial vasculature.. Use of primary human endometrial endothelial cells (HEECs) in this work was evaluated as a possible screening tool for effects caused by EDCs on human endometrial vasculature and subsequently on various endometrial functions.. In this study HEEC and ...
