Secretes fluid that makes up most Seminal Vesicle of the components of the semen (sugar and proteins) b. Prostate Secretes a slightly alkaline milky fluid glands that is discharged as a part of semen ( increase the motility of semen) c. Secretes a thick and clear mucus that Bulboureth lubricate and neutralizes the any trace of ral gland acidic urine in the urethra, provides some lubrication for the tip of the penis during intercourse  What is the Function of Male Reproductive System? Function Produce male reproductive cells ( sperm cells), hormones and accessory material. Deposit sperm cells in female reproductive organ. Spermatogenesis is the process of sperm cell development.  Trace the pathway of the Sperm or semen? Testosterone is a hormone that is responsible for many of the physical characteristics specific to adult males WHICH COME FIRST!

PENIS TESTES URETHRA VAS DEFERENS Assignment 1.Determine the hormones produce in Male Reproductive System. 2.Explain Hormonal Regulation in Male Reproductive system.  A Testes: Interstitial Cells Testes: Sustentacular Cells Fill in the gaps Structural between cells found seminiferou in s tubules Seminiferou s tubules  Inhibits FSH secretion Inhibin Released in amounts proportional to sperm count High sperm count-high inhibin Low sperm count –Low inhibin Feedback mechanism in male reproductive system: The male reproductive system utilizes a negative feedback loop to regulate the production of hormones and sperm cells. When sperm count is high, inhibin is released, suppressing FSH and LH production, leading to decreased sperm production. Conversely, when sperm count is low, inhibin levels decrease, allowing for increased FSH and LH production, stimulating sperm cell production. This Guide questions: 1. What is the hormone/s produce by the following: a. Hypothalamus b. Pituitary glands c. Testes Guide questions: 2. Which are the hormones controlling the production of Testosterone? 3. Which are the hormones stimulating the production of sperm cells? 4. How does the inhibin affect the production of sperm cells? Complete the flow chart  1 Inhibits FSH secretion 2 Inhibin Released in amounts 3 4 proportional to sperm count High sperm count-high inhibin Low sperm count –Low inhibin Puberty is the time in life when a boy or girl becomes sexually mature. It causes physical changes and affects boys and girls differently. RA 10354: Reproductive Health Law The recently enacted Reproductive Health Law (RA 10354) or the Responsible Parenthood and Reproductive Health Act is perhaps 20 Towards a Better Future for the Youth the most responsive policy in the country in terms of addressing adolescent reproductive health. RA 10354: Reproductive Health Law RA 10354’s provisions ensuring adolescent reproductive health are in the forms of providing information, family planning supplies, and penalizing those who refuse to provide reproductive health services and information to adolescents on the basis of age. Assignment Draw a female reproductive organ and label the parts. Determine the function.  Functions of Female reproductive system Produce female sex cells (egg cells). Produce female sex hormones Receive sperm cells from the male. Nurtures the development of and provides nourishment for the new individual. Fundus Female Reproductive System Parts Characteristics and Function OVARIES / Contains ovarian follicles that GONADS produce oocyte/egg cells FALLOPIAN Serves as passageway of eggs TUBES from the ovary to the uterus; site /OVIDUCTS of egg fertilization  Female Reproductive System Parts Characteristics and Function UTERUS Serves as site of egg implantation; is where fertilized egg develops Made up of Fundus, body and cervix Cervix -the lower, narrow end of the uterus (womb) that connects the uterus to the vagina (birth  Female Reproductive System Parts Characteristics and Function Vagina Organ for copulation Function to receive the penis during intercourse Allows menstrual flow and childbirth The vaginal opening is covered by a thin mucous membrane called the hymen ( not reliable indicator Oogenesis is the process of formation of female gametes Puberty is the time in life when a girl becomes sexually mature and able to produce egg. Female Sex Hormones regulates the menstrual regulates supportsthe pregnancy cycle menstrual cycle  Fallopian 2 Tube Ovary 1 Uterus 3 Cervix 4 Vagina 5 Unlocking of Terms Ovulation 1. __________________ - occurs when your ovary releases an egg Menarche 2. __________________ -menstruation is a woman's monthly bleeding, often called your “period.” Menstruatio n 3. _____________________ - is defined as the first menstrual period in a female adolescent Unlocking of Terms Menopau 4. _________________ se - woman's last period Fertilizati on 5. __________________ -is the process of fusion of male and female sex cells(gametes). It is the process which occurs after pollination. Menstrual cycle the length of the menstrual cycle varies from woman to woman, but the average is to have periods every 28 days. Regular cycles that are longer or shorter than this, from 23 to 35 days, are normal. The menstrual cycle is the time from the first day of a woman's period to the day before her next period.  MENSTRUATIO N LUTEAL PHASE PHASE FOLLICULAR PHASE OVULATION PHASE Phases This is “period” when the endometrium or lining of the uterus sheds over 3-7 days if there is no pregnancy. This is when several eggs mature inside small cysts or follicles. This is when an egg is released from the biggest follicles and travels through the fallopian tube, where it can be fertilized. If it is not fertilized, it dissolved in about 24-28 hrs. This is when the endometrium ( lining of the uterus ) is thick and prepared to support a Quiz 1 1. Serves as site of egg implantation; is where fertilized egg develops 2. Produces egg 3. Serves as passageway of eggs from the ovary to the uterus; site of egg fertilization 4.
