chromosomal microarray is the same thing as

molecular karyotyping (MK)

Occurs after fertilization and results in baby with 2 different cell lines - each having a different chromosomal number

mosaicism

caused by an interaction of many genes and environmental factors (cause of most congenital malformations)

multifactorial inheritance

assesses for uterine or vaginal anomalies

pelvic examination

pungent square

in 40% of couples who are infertile, inability to conceive is due to male infertility. this test is the first in an infertility workup because it is less expensive and less invasive

semen analysis

after ovulation, as progesterone increases, the BBT does what

slightly increases

so the MD can access the uterus easier

Based on current evidence = offer CMA as the first-tier genetic test for patients with unexplained: (DD) =developmental delay (ID) = intellectual disability (ASD) = autism spectrum disorders (MCA) = multiple congenital anomalies

the international standards for cytogenetic arrays (ISCA)

insertion of small flexible agent through the vagina and cervix into the fallopian tubes. this results the development of scar tissue in the tubes preventing conception.
