- The identification of these genes in cumulus cells can serve as a novel, non-invasive marker to identify abnormal oocytes and thus ultimately improve IVF success rates," said Patrizio, professor in the Department of Obstetrics, Gynecology & Reproductive Sciences at Yale. (health.am)
Polycystic ovarian1
- By 1991, the first human pregnancy was recorded using IVM followed by IVF, and in 1994 the first birth using IVM oocytes from polycystic ovarian syndrome patients was recorded highlighting that PCOS patient's oocytes are capable of maturation. (wikipedia.org)
Manipulation1
- Other attempts to overcome ooplasmic aging have utilized oocyte manipulation at a subcellular level. (arvigen.com)
Cleavage5
- After 48 hours the culture was evaluated for the ability of embryo cleavage. (ifory.id)
- Embryos cleavage, ovarian reproductive status, Bali cattle. (ifory.id)
- Understanding the association between Cell-free DNA levels in embryo CM and the quality of embryo cleavage could help improve the quality of IVF techniques. (who.int)
- This prospective study was conducted with 96 spent CM from patients undergoing IVF cycle, in order to determine relationships of Cell-free DNA levels in embryo CM with embryo cleavage quality on day 3. (who.int)
- We conclude that cel -free DNA levels in CM might be associated with delayed embryo cleavage. (who.int)
Field of reproductive2
- Although best known for his involvement with "the pill," Chang also made a number of discoveries throughout his scientific career involving a range of topics within the field of reproductive biology. (asu.edu)
- Microarray technology provides new insights into the field of reproductive biology as well as other fields of medicine and biology. (bioone.org)
Occurs2
- They showed maturation occurs in isolation from normal follicular environment. (wikipedia.org)
- Female infants have 6 to 7 million oocytes at 20 weeks of gestation, when progressive atresia occurs, resulting in 1 to 2 million oocytes at birth, approximately 25,000 at the age of 37 years, and 1000 at the age of 51 years, the average age of natural menopause in the United States.

PCOS1
- Women with PCOS have an imbalance of reproductive hormones that tend to produce higher levels of male hormones (androgens) causing missed or irregular menstrual periods. (co.ke)
IVEP2
- The in vitro embryo production (IVEP) is very stressful for gametes. (vetmedmosul.com)
- As a result, developing a culture medium capable of effectively reducing ROS in vitro embryo production (IVEP) protocols is of tremendous importance (10). (vetmedmosul.com)
Specialist in reproductive medicine1
- He is acknowledged as a specialist in reproductive medicine both by ESHRE (European society of Human Reproduction) and EBCOG (European Board and College of Obstetrics and Gynecology). (embryolab-academy.org)
Improves1
- PGTa allows for better embryo selection, which improves implantation rates with single embryo transfer and reduces miscarriage rates. (medscape.com)
FERTILITY PRESERVATION4
- Fertility preservation is the technique of conserving or storing one's. (lushfertility.in)
- Fertility Preservation is the latest advancement in reproductive medicine where patients can preserve or retain their fertility or ability to procreate. (oasisindia.in)
- Our Medical Director, Dr. Durga G Rao is a pioneer in Fertility Preservation Techniques. (oasisindia.in)
- The aim of this review was to analyze the reproductive potential of women harboring a genetic mutation affecting the DNA repair system and explore the efficacy and safety of existing fertility preservation strategies in these patients. (bmj.com)
Woman's2
- The number of embryos transferred is determined by the woman's age and likelihood of response to IVF. (msdmanuals.com)
- The number and quality of a woman's oocytes declines with age. (medscape.com)
Implantation rates1
- Despite major advancements in assisted reproductive techniques, the implantation rates remain relatively not high. (peertechzpublications.com)
