| blastocyst | In mammalian development, cleavage produces a thin walled hollow sphere, whose wall is the trophoblast, with the embryo proper being represented by a mass of cells at one side. The blastocyst is formed before implantation and is equivalent to the blastula. (18 Nov 1997) |

| blastocystina | A suborder of protozoa of the class lobosea. (12 Dec 1998) |
| blastocystis | A genus of protozoa of the suborder blastocystina. It was first classified as a yeast but further studies have shown it to be a protozoan. (12 Dec 1998) |
| blastocystis hominis | A species of parasitic protozoa found in the intestines of humans and other primates. It was classified as a yeast in 1912. Over the years, questions arose about this designation. In 1967, many physiological and morphological b. Hominis characteristics were reported that fit a protozoan classification. Since that time, other papers have corroborated this work and the organism is now recognised as a protozoan parasite of humans causing intestinal disease with potentially disabling symptoms. (12 Dec 1998) |
| blastocystis infections | Infections with protozoa of the genus blastocystis. The species b. Hominis is responsible for most infections. Surveys have generally found small numbers of this species in human stools submitted for parasitologic studies, with higher positivity rates and organism numbers being reported in aids patients and patients with other immunosuppressive diseases. Symptoms include abdominal pain, diarrhoea, constipation, vomiting, and fatigue. (12 Dec 1998) |

| blastocyst |
An early-stage embryo (day 5 or 6) comprising 30-150 cells. The blastocyst consists of a sphere made up of an outer layer of cells (the trophectoderm), a fluid-filled cavity (the blastocoel), and a cluster of cells in the interior (the inner cell mass, from which stem cells may be derived). The size of a blastocyst is approximately 0.15mm.

| blastocyst transfer |
In blastocyst transfer, infertile women are implanted with embryos that have matured for five days (to the blastocyst stage). By using these more developed embryos, we are able to identify those that are most likely to result in a successful pregnancy. Initial studies published by Dr. David Gardner of the Colorado Center showed that a blastocyst transfer increased the implantation rate per embryo from 21% to 46%.

| blastocyst transfer |
This is performed when the embryos are cultivated for 4-5 days to approximately 64-cell stage at embryo transfer.

| blastocyst |
An advanced stage of embryo development, the embryo consists of an outer thin layer of cells, which later develops to placenta and an inner cell mass later develops to fetus.
