Document Summary
If conception occurs during a time of poor maternal health status, the health of the mother, fetus, and the future health of the offspring can be compromised: men"s health also plays a key role in healthy pregnancy. Female reproductive system and hormones: the menstrual cycle, typically lasts about 28 days, divided into two distinct phases: first half= follicular stage; second half= luteal stage. Follicle- stimulating hormone, luteinizing hormone, estrogen, and progesterone. The menstrual cycle: luteal phase begins about 14 days after the follicular phase estrogen stimulates the release of lh, which causes the follicle to release its egg from the ovary and ovulation occurs. 1 empty follicle becomes the corpus luteum, which secretes progesterone progesterone readies the uterus for a fertilized egg if the egg is not fertilized, menstruation occurs. Male reproductive system and hormones: three major hormones involved in the male reproductive system: follicle-stimulating hormone (fsh), luteinizing hormone (lh), and testosterone. Fsh makes sperm in a process called spermatogenesis.
