Back to Pregnancy and child. An important fact to highlight from the start, which has somewhat been overlooked in media reports, is the study recruited only women who were seeking IVF treatment for fertility problems. So any results may not be representative of women in general.
Every month, the reproductive organs in a healthy woman prepare for pregnancy. After ovulation the egg lives for 12 to 24 hours and must be fertilised in that time if a woman is to become pregnant. The burst of oestrogen just before ovulation also works inside the neck of the uterus the cervix to make protein-rich clear jelly that covers the top of the vagina during sex.
The aim of this study was to compare the rate of maturation, fertilization, and embryo development of in vitro -matured human oocytes derived from pregnant and non-pregnant women. Immature oocytes were obtained by needle aspiration from 49 pregnant women group 1 who underwent a cesarean section at term and 77 non-pregnant women group 2 who underwent a gynecological operation during the same period 8 months. Healthy immature oocytes in group 1 and in group 2 were cultured and assessed for maturation 36 hours later.
The female reproductive cycle is complex. Hormone levels are constantly changing as girls become women, and as women ride their cycles through phases every month. Then, when women reach middle-age, they go through even more changes as their hormones take a drastic dive.
Fertility changes with age. Both males and females become fertile in their teens following puberty. For girls, the beginning of their reproductive years is marked by the onset of ovulation and menstruation.
Most mothers who are nursing through pregnancy notice a decrease in milk supply by mid-pregnancy, but sometimes as early as the first month. During pregnancy, the mature milk is also making a gradual change to the colostrum which is present at birth. Supply may increase toward the end of pregnancy as colostrum production kicks in.
Steroid injections given to pregnant women before premature birth may increase the child's risk of later behavioural difficulties, a study has found. Mothers who are expected to give birth prematurely are often given an infusion of glucocorticoids, which mimic the natural hormone cortisol. Cortisol is produced in the fetus in the late stages of pregnancy to help the lungs develop, preparing the baby for life outside the womb.
