Figure 48. Oocytes are usually fertilized within hours of ovulation (Austin, 1957; Harper, 1994). Normal reproduction in the female depends on hormones, which are specific chemical substances produced by specialized glands called endocrine glands. Only one survives usually. The germ cell from the male (sperm) will then fuse with the germ cell of the female (ovum) during reproduction to reform a cell with 23 pairs of homologous chromosomes. MCQs on Female Reproductive System : 1. Apart from the above-mentioned functions, the female reproductive system is also involved in the production of female sex hormones to maintain the reproductive cycle. T F 7. Fertilization of the ovum usually occurs in the fallopian tubes by the spermatozoa released by the male during copulation. Luteinizing hormone (LH): Promotes progesterone production.

The ovaries store and release the ovum and produce the 2 principal female sex hormones, estrogen and progesterone. Intrauterine system (IUS) with progestogen, sold under the brand name Mirena among others, is an intrauterine device that releases the hormone levonorgestrel into the uterus. While other hormones prepare the uterus so a baby can grow in it, other hormones still control the stretching of the uterus during pregnancy. Endocrine glands in the reproductive system produce sex hormones that are responsible for secondary sex characteristics in men and women. Oestrogen causes eggs to mature in ovaries once a girl hits puberty. Female Reproductive Endocrinology. Female Reproductive System. HORMONAL CONTROL OF FEMALE REPRODUCTIVE CYCLES.

Birth control methods include barrier methods, hormonal birth control, intrauterine devices (IUDs), sterilization, and behavioral methods.They are used before or during sex while emergency contraceptives are effective for up to five days after sex. The follicles produce hormones that control the growth and release of eggs from the ovaries. If an ovum is Regardless of whether the organism is more internally or externally biased in terms of its reproductive control, estradiol produced by developing follicles in the ovaries has a central role. This usually occurs between days 13 and 15 of the menstrual cycle. Unit 3: Reproductive Systems and the Menstrual Cycle 39 Male and female reproductive systemsinclude all of the structures and organs involved in fertilization and implantation.

The ovarian cycle involves the monthly formation and release of a secondary oocyte and the ovarian events that take place in preparation for pregnancy. Note hormone origins (production stimuli), production sites and target cells as well as tissue effects and feedback systems. Alcohol and the hypothalamic-pituitary-adrenal axis. 23 pairs of homologous chromosomes become 23 chromosomes.
