2. Secondary sex ethics -Scrotum, epididymis, vas deferens, ejaculatory duct, urethra, penis.
3. Accessory glands-seminal vesicles, prostate, bulbourethral and other glands.
Testes are two male reproductive glands or male gonads lying in the scrotum which produce sperms. Penis is directly used during sexual intercourse for insertion in female vagina. Secondary sex characters in male also differentiate an individual with the female anatomically, physiologically and psychologically.

Anatomy of female sex organs

Q.19. Describe in brief the anatomy of female sex organs?

Ans. The female sex organ consist of :
1. Primary sex orgasm -Ovaries
2. Secondary sex organs-Fallopian tubes, uterus, vagina and vulva.
3. Accessory glands-Breasts, greater and lesser vestibular glands, mucous glands of cervix of uterus, vaginal orgasm glands.
Ovaries are two female gonads which produce ova. Uterus or womb is the organ which bears the focus from fertilization till parturition. Vagina is a canal in which male penis is inserted during the sexual act. Vulva consists of mons pubis, labia majora, labia minora, clitoris, vestibule, external urethral orifice and vaginal orifice. Breasts or mammae are basically the organs of lactation. Anatomical difference in secondary sex characteristics of the two genders lies in hair distribution, larynx or voice box, muscles, subcutaneous fat, body figure, height, bones and brain.

Role of hormones in sexuality

Q.20. What is the role of hormones in sexuality?

Ans. Sexual behavior development is basically controlled by gonadotrophic hormones secreted by anterior pituitary gland or adenohypophsis. Gonadotrophic hormones or gonadotrophins or sex hormone stimulating hormones secretion starts at the onset of puberty which acts on gonads and make them secrete sex hormones. The gonadotrophic hormones are follicle stimulating hormone, luteinizing hormone and luteotrophic hormone which help in sperm production in male and ova production in female along with cyclical changes during normal menstrual cycle. Male sex hormones or androgens which are mostly in the form of testosterone are secreted by the testes and in traces by the cortex of adrenal glands and ovaries. Testosterone regulates the sexuality of man. Female sex hormones are oestrogens and progesterone. Oestrogens are secreted by the ovaries and in minute quantity by the adrenal cortex and testes. Progesterone is secreted by the ovaries, placenta, corpus luteum and in very small quantity by the adrenal cortex. The female sex hormones regulate the entire sexuality of woman. Human chorionic gonadotrophin, human placental lactogen and relaxin hormones are produced in a woman during pregnancy for maintaining pregnancy and easy parturition. Posterior pituitary hormones are oxytocin and vasopressin. Oxytocin helps in conception, sperm transportation, uterine contraction during labour, controlling postpartum haemorrhage and ejection of milk from breast after birth of baby. Oxytocin hormone is responsible for feeling of love between man and woman as well as between mother and child along with prolactin hormone and endorphins. A woman secretes chemicals called pheromones which are the cause of smell emitted by her causing attraction to man. It must be , remembered that pheromones are destroyed by contraceptive pills. Vasopression or antidiuretic hormone “ has a sex role in checking of post partum uterine haemorrhage in female.
