Hysteroscopic Subendometrial Embryo Delivery (SEED), Mechanical Embryo Implantation
Background A major hurdle to improved in vitro fertilization (IVF) success rate is defective endometrial receptivity and implantation. Various techniques have been advocated to increase implantation while reducing side effects. Currently, embryo transfer (ET) is performed blindly without direct visualization. As such, we sought to develop a technique utilizing a flexible minihysteroscope with a...
متن کامل10. Human embryo cryopreservation and its effects on embryo morphology
Cryopreservation may have a variety of effects on embryo morphology, ranging from subtle damage on intracellular organelles, cytoplasm, or processes that can negatively affect normal cell development, to overtly blatant effects such as the lysis of one or more blastomeres. Many underlying factors can influence the outcome of cryopreservation, e.g. the quality of the oocyte or embryo itself will...
متن کاملDevelopmental morphology and structural homology of corolla-androecium synorganization in the tribe Amorpheae (Fabaceae: Papilionoideae).
Comparative developmental morphology was used to assess structural homology of flowers in Dalea, Marina, and Psorothamnus of the tribe Amorpheae (Fabaceae: Papilionoideae). Dalea, Marina, and some species of Psorothamnus have an unusual petal-stamen synorganization (stemonozone) in which free petals are inserted on a region that is continuous with fused stamen filaments. Developmental studies o...
متن کاملFlower morphology, pollination biology and mating system of the complex flower of Vigna caracalla (Fabaceae: Papilionoideae).
BACKGROUND AND AIMS Vigna caracalla has the most complex flower among asymmetrical Papilionoideae. The objective of this study was to understand the relationships among floral characteristics, specialization, mating system and the role of floral visitors under different ecological contexts. METHODS Five populations were studied in north-western Argentina, from 700 to 1570 m a.s.l. Anthesis, c...
متن کاملArborescent palm seed morphology and seedling distribution.
This study examines how the seed morphology of two large arborescent palms, Attalea maripa (Aubl.) Mart. and Astrocaryum aculeatum G. Mey, may affect their seed shadow in a seasonally dry Amazonian forest. In addition to being smaller and produced in larger numbers than those of A. aculeatum, A. maripa seeds also presented a substantially lower amount of nutritional reserves available for the e...
