Literature Review.
Live Birth Rates in Women Under 38 Years Old with AMH Level : Morcel K A retrospective research found that in their first IVF +/- ICSI cycle 1, women under the age of 38 with AMH levels of less than 1.2 ng/ml had lower biochemical pregnancy rates (16.6%) than those with levels of 1.2 ng/ml or more (37.9%). However, the study discovered that the rates of spontaneous miscarriage (9.1% vs. 15.2%) were the same in the two groups. In a different research, it was discovered that AMH levels did not indicate the quality of the oocytes in older women having IVF/ICSI cycles.
Impact of an estrogen replacement regimen on live birth rate in frozen-thawed good-quality embryotransfer.: Özmen B An oestrogen replacement regimen may increase the live birth rate in frozen embryo transfer (FET) cycles, according to a retrospective cohort research .The study discovered that a step-up 4-mg regimen delivers optimal-dose oestrogen to thicker endometrial in a sufficient amount of time, which has a striking propensity to improve clinical pregnancy and live birth rates. Nevertheless, another research discovered that natural cycle FET boosts live-birth rates compared to hormone replacement therapy in young women with normal menstrual periods. Therefore, the type of endometrial preparation chosen may depend on the features and preferences of each patient.
Sperm cryopreservation does not affect live birth rate in normozoospermic men: analysis of 7969 oocyte donation cycles.: Torra-Massana M Men who have normal sperm analysis findings, which means that their semen sample satisfies the semen requirements as per the WHO Manual for Human Semen Analysis, are said to be normozoospermic. A semen sample that displays typical features on a seminogram is referred to by the word. The live birth rate in normozoospermic males is unaffected by sperm cryopreservation, according to a research that examined 7969 oocyte donation cycles.
Higher baseline alanine aminotransferase level is associated with lower live birth rate after freeze-thawed embryo transfer.: Zhang S , Xu H , Chen J A greater baseline alanine aminotransferase (ALT) level has been linked to a reduced live birth rate following freeze-thawed embryo transfer, according to several sources. According to one study, individuals with moderate to severe ovarian hyperstimulation syndrome (OHSS) who have aberrant ALT levels may experience poor pregnancy outcomes and a lower live birth rate.
He Puzzle of Falling US Birth Rates since the Great Recession: Kearney, Melissa S.1 , Levine, Phillip B.2 He search results provide information on the puzzle of falling US birth rates since the Great Recession. The decline in births cannot readily be explained by changing population demographics, such as aging or changing racial and ethnic composition. The decline in fertility in the United States has dropped temporarily during periods of economic decline, such as the Great Depression of the 1930s and the Great Recession of 2007-2009. The decline in birth rates in the United States between 2007 and 2020 is a dramatic one, and the reasons for this decline are not yet fully understood. The studies explore possible explanations for the decline in birth rates, including economic factors, changing social norms, and the impact of the COVID-19 pandemic.
A Neoclassical Growth Model With Endogenous Birth And Mortality Rates: Wei-Bin Zhang1 The information about a neoclassical growth model with endogenous birth and death rates may be found in the search results. In order to generate an S-shaped association between life expectancy and GDP growth, the research investigate the relationship between the drop in death rates and economic growth. The crude birth rate less the crude mortality rate plus net immigration equals the population growth rate. In neoclassical economic growth models, the studies calculate the impact of chronic noncommunicable illness death rates on economic growth. The analyses also take into account scenarios in which a drop in mortality leads to more expenditures in human capital on an individual level and an uptick in economic growth.
Live birth rate and neonatal outcomes following interventional embolization of hydrosalpinx: Interventional embolisation of hydrosalpinx may affect the live birth rate and neonatal outcomes, according to a number of sources. One research looked at the effects of hydrosalpinx interventional embolisation on live birth rate and neonatal outcome following the surgery. A different investigation discovered that hydrosalpinx can lower the IVF-ET clinical pregnancy rate
The Live Birth Rate Of Vitrified Oocyte Accumulation For Managing Diminished Ovarian Reserve: A Retrospective Cohort Study: Kuan-Sheng Lee , Ming-Huei Lin According to a number of sources, a retrospective cohort research sought to ascertain if the live birth rate (LBR) for managing decreased ovarian reserve (DOR) is improved by the vitrified oocyte accumulation method. The study discovered that vitrified oocyte accumulation has been employed for controlling DOR and that it enhances the LBR for regulating DOR. Oocytes subjected to vitrification-thawing showed an 85.7% survival rate.
Increased Blastomere Number Is Associated With Higher Live Birth Rate In Day 3 Embryo Transfer: Lifeng Tian Leizhen Xia The presented search results show a correlation between day 3 embryo transfer’s greater live birth rate and increased blastomere number. According to studies, the live birth rate rises noticeably as the number of day 3 embryo cells rises. According to one study, miscarriage rates were comparable for embryos with 8 to 9 cells and those with 10 or more cells. Another research made the claim that the rate at which sibling embryos grow may be a good indicator of the live birth rate after the transfer of D3 cleavage embryos.
Does paternal age affect the live birth rate in donor oocyte cycles? A systematic review and meta-analysis: Begon, Emmanuelle , Lefebvre, Tiphaine Inferred from the search results given is that the live birth rate in donor oocyte cycles is negatively impacted by increasing paternal age in a small but statistically significant way. The live birth rate is negatively impacted by male age in a small but statistically significant way, according to a meta-analysis based on 10,527 egg donation cycles. In a total of 237 ovum donor cycles, another study discovered a substantial reduction in the live birth rate with increasing paternal age.However, it is significant to stress that more study is required to corroborate these results.
CONCLUSION:
The Research’s Findings Offer Crucial Conclusions On Live Birth Rates In Particular Circumstances. Retrospective Research On AMH Levels In Women Under The Age Of 38 Found That Those With Levels Below 1.2 Ng/Ml Had Lower Biochemical Pregnancy Rates Than Those With Higher Levels. However, The Two Groups’ Rates Of Spontaneous Miscarriage Were Comparable. Another Study Found That An Oestrogen Replacement Regimen, Especially A Step-Up 4-Mg Regimen That Distributes Oestrogen To The Endometrium Optimally, May Boost The Live Birth Rate During Frozen Embryo Transfer Cycles. Alternative Studies, However, Highlighted The Potential For Natural Cycle Frozen Embryo Transfer To Result In Greater Live Birth Rates Than Hormone Replacement Treatment In Young Women With Normal Menstrual Cycles. The Significance Of Every Patient’s Wishes. Sperm Cryopreservation Was Found To Have No Effect On Live Birth Rates In The Setting Of Normozoospermia Males, Demonstrating Its Acceptability For Fertility Preservation. In Contrast, Persons With Moderate To Severe Ovarian Hyperstimulation Syndrome (OHSS) Have Been Found To Have Lower Live Birth Rates Following Freeze-Thawed Embryo Transfer When Their Baseline Alanine Aminotransferase (ALT) Levels Are Greater. Last But Not Least, The Mystery Of The Decline In US Birth-Rates During The Great Recession Remains Complicated, With Probable Contributing Variables Including The COVID-19 Epidemic, Changing Population Demographics, Economic Issues, And Changing Societal Standards. To Completely Comprehend The Underlying Causes Of The Dramatic Fall In Birth Rates During This Time, More Study Is Required.
The Goal Of The Neoclassical Growth Model With Endogenous Birth And Mortality Rates Is To Produce An S-Shaped Link Between Life Expectancy And GDP Growth By Investigating The Relationship Between The Drop In The Death Rate And Economic Growth. Studies In This Area Also Take Into Consideration The Impacts Of Chronic Noncommunicable Disease Death Rates On Economic Growth, Taking Into Account The Effects On Investment In Human Capital And Total Economic Growth. Live Birth Rates And Neonatal Outcomes May Be Affected By The Interventional Embolization Of Hydrosalpinx. Studies Show How This Method Affects The Live Birth Rate And Neonatal Outcomes While Also Showing How Hydrosalpinx Negatively Affects The Clinical Pregnancy Rate In IVF-ET. The Vitrified Oocyte Accumulation Technique For Treating Decreased Ovarian Reserve (DOR) Has The Potential To Increase The Live Birth Rate.
An Increase In Blastomere Number After Day 3 Embryo Transfer Is Associated With A Greater Percentage Of Live Births. Studies Have Shown That When The Number Of Blastomeres In Day 3 Embryos Rises, The Live Birth Rate Increases Noticeably. Also Indicated As A Potential Predictor Of The Live Birth Rate Following The Transfer Of Day 3 Cleavage Embryos Is The Growth Rate Of Sibling Embryos.
The Live Birth Rate In Donor Oocyte Cycles Is Negatively Impacted By Paternal Age In A Minor But Statistically Significant Way, According To A Systematic Review And Meta-Analysis. The Examination Of Egg Donation Cycles Showed That The Live Birth Rate Decreased As Paternal Age Increased. To Verify These Results, However, More Study Is Required.
In conclusion, these studies provide information on a range of variables that might affect live birth rates, including economic development, mortality rates, certain medical procedures, and demographic variables like paternal age. Our understanding will be improved, and measures to increase live birth rates and reproductive outcomes will be informed by ongoing study in these areas.
