Hormones released by the hypothalamus and anterior pituitary glands are typically responsible for these alterations.Girls start puberty at an average age of 11, while boys start at an average age of 12. But because everyone is different, don't be concerned if your child hits puberty sooner or later their peers. Puberty can start at any age between 8 and 14, and it's perfectly natural. It might take up to four years to complete the procedure.MaleFemaleFollicle-stimulating hormone (FHS)Luteinizing hormone (LH)TestosteroneEffects of TestosteronesIncreases muscle mass and strengthPromotes growth of long bonesIncreases basal metabolic rateEnhances production of red blood cellsProduces enlargement of vocal cordsAffects the distribution of body hairGonadotropin-releasing hormone (GnRH)follicle-stimulating hormone (FHS)Leutenizing hormoneEstrogenProgesteroneAfter ovulation, progesterone prepares the endometrium for the possibility of pregnancy. It causes the lining to thicken in preparation for a fertilized egg. It also prevents the uterus's muscular spasms from causing the body to reject an egg.Menarche, or the start of menstruation, occurs between the ages of 9 and 17 (average of 12.4 years). Anovulatory cycles are common in the early stages of pregnancy. Within 6 to 2 years following menarche, regular cycles are generally formed. The flow (menses) occurs every 28 days on average, with a range of 23-35 days. The blood loss ranges from 30 to 80 mL and lasts 4 to 6 days (ranges 2-9 days). Heavy bleeding is defined as saturating a pad or tampon in less than 1 hour. Blood, mucus, and endomentrial cells make up menstrual blood, which is dark red.Menstrual cycleUterine ChangesRelationshipOvarian changesRelationshipPreovulatory Phase/Follicular PhaseHypothalamus releases gonadotropin-releasing hormone through the portal system to theanterior pituitary systemSecretion of follicle stimulating hormone (FSH) by anterior lobe of the pituitary gland stimulatesgrowth of follicles.Estrogen produced by the follicle stimulates increased secretions of lutenizing hormone (LH) bythe anterior lobe of the pituitary gland.The follicle ruptures and releases an ovum into the peritoneal cavityLuteal Phase Begins with ovulation.Body temperature decreases and then increases by 0.5oF to 1oF around the time of ovulation.Corpus luteum is formed from follicle cells that remain in the ovary after ovulation.Corpus luteum secretes estrogen and progesterone during remaining 14 days of the cycle.Corpus luteum degenerates (corpus albicans) if the ovum is not fertilized, and secretion ofestrogen and progesterone declinesDecline of estrogen and progesterone stimulates the anterior pituitary to secret more FSH andLH, initiating a new reproductive cycle.Menstrual PhaseSecretory Phase Ischemic PhaseConsists of 4 to 6 days of bleeding as the endometrium breaks down because of the decreasedlevels of estrogen and progesterone.The level of FSH increases, enabling the beginning of the cycleLasts about 9 days.Estrogen stimulates proliferation and growth of the endometrium.• A estrogen increases, it suppresses secretion of FSH and increases secretion of LH.• Secretion of LH stimulates ovulation and development of the corpus luteumOvulation occurs between days 12 and 16.• Estrogen level is high, and progesterone level is lowLasts about 12 days and follows ovulation.This phase is initiated in response to the increase in LH level.The graafian follicle is replaced by corpus luteumProgesterone prepares the endometrium for pregnancy if a fertilized ovum is implantedCorpus luteum degenerates (corpus albicans) if the ovum is not fertilized, and secretion ofestrogen and progesterone declinesCorpus luteum degenerates (corpus albicans) if the ovum is not fertilized, and secretion ofestrogen and progesterone declinesBlood supply to the endometrium decreases.Without progesterone and estrogen, the endometrium will begin to slough off initiating themenstrual phase.

This is a concept map about human sexuality. Gender and sexuality are fundamentally essential forces that affect every part of our lives: our gender and sex help us understand our bodies, brains, and selves. Our medical, legal, educational, and political institutions are all organized around legal definitions and societal expectations regarding women and men's sex and reproduction.
