Does Aging Affects Fertility and Pregnancy ?

  The prime reproductive years for women are from their late teens to late 20s. Age 30 marks the onset of a reduction in fertility (the capacity to become pregnant). Once you're in your mid-30s, this drop accelerates. By the age of 45, most women's chances of spontaneously becoming pregnant have significantly decreased. The quantity of eggs in a woman's ovaries is fixed from birth. As women age, their egg supply declines. Additionally, older women are more likely to have eggs with faulty chromosomes. Additionally, uterine fibroids and endometriosis are two conditions that might impact fertility and which are more common in older women. Approximately 1 in 4 women will become pregnant during any one menstrual cycle for healthy couples in their 20s and early 30s. One in ten women by the age of 40 will become pregnant each menstrual cycle. Age also reduces a man's fertility, though not as consistently.

Why does depression make you lose your memory?

  Declarative memory, which involves the retention of facts and events, may be less effective when a person is depressed. The hippocampus , a stress-sensitive region of the brain involved in learning and memory, is often smaller in depressed individuals. Low hippocampus volume may be the cause of poor memory. These results provide credence to the hypothesis that melancholy may impair declarative memory, which involves remembering facts and experiences. The study's authors postulate that depression might inhibit the growth of new nerve cells . This can make it challenging to create or access fresh memories. Acute and long-term alterations brought on by stress can harm some parts of the brain. The most common memory impairment caused by excessive stress hormone production is long-term delayed recall memory, although it can also improve short-term, instant recall memory. This improvement is most noticeable in emotional memory.
