The cycle of the bitch
A few terms at the beginning:
ovary - ovary
fallopian tubes - salpinx
eggs - follicle
ovulation - ovulation
ovulation - the release of eggs from the ovary into the fallopian tube
vulva - vulvar
The cycle of the bitch can be divided into 4 sections:
a) Vorbrunst - pro-oestrus (5-15 days)
b) heat - estrus (5-15 days)
c) regression - metestrus (diestrus) (90-120 days)
d) rest - anoestrus (about 60-90 days)
(The details of the duration vary depending on source.)
a) proestrus
here is the beginning of the first visible bloody discharge from the vulva and a swelling the latter. The swelling increases in the course of proestrus to grow. During this period, mature in the ovaries, the follicles (eggs) approach.
b) estrus
The vaginal discharge can change from bloody to clear and the swelling of the vulva may go back a little. In this phase, the ovulation. So the release of the follicle into the fallopian tube. The follicles are usually capable of fertilization 2-3 days after ovulation and this for about 3 days.
c) metestrus
The swelling the vulva is declining and it is no longer present sexual acceptance. This phase is referred to as luteal phase, which lasts about 9 weeks.
In pregnant bitches, this phase lasts about 59-63 days.
d) anoestrus
The progesterone level in serum is to \u0026lt;1 ng / ml or decreased after the end of lactation. Rest of the uterus.
There are factors that influence this phase. So here the race, rank in the pack, the age flows etc. a role. So it can be of different length stages of anoestrus of 15 - are 265-days.
