The shared terminal duct of the reproductive and urinary system in the human male is: 
Urethra is a tube that connects the urinary bladder to the genitals for the removal of fluids from the body. The urethra travels through the penis, and carries semen as well as urine.
The main function of mammalian corpus luteum is to produce: 
The corpus luteum is a temporary endocrine structure in female mammals, that is involved in the production of relatively high levels of progesterone.
Thus, the correct answer is option (B)
Select the correct option describing gonadotropin activity in a normal pregnant female: 
Synthesis of estrogen and progesterone due to high level of hCG is a normal gonadotropic activity in a normal pregnant female.
Which of these is not an important component of initiation of parturition in humans ? [2015 RS]
Capacitation refers to changes in the : [2015 RS]
Capacitation and acrosomal reaction occur before fertilization. The process of capacitation happens when sperms enter vagina. During this period, cholesterol vesicles are removed from the acrosome.
Which of the following cells during gametogenesis is normally diploid? [2015 RS]
During gametogenesis, spermatogonia are diploid because of undergoing the process of meiosis.
Which of the following events is not associated with ovulation in human female? [2015 RS]
A childless couple can be assisted to have a child through a technique called GIFT. The full form of this technique is : [2015 RS]
GIFT (Gamete Intra Fallopian Transfer) is a technique helping to have a child.
Which of the following layers in an antral follicle is acellular ? [2015 RS]
Follicles that form an antrum during maturation are called antral follicle or Graafian follicle. During the development of the follicle, a glycoprotein polymer capsule called the zona pellucida which is acellular, forms around the oocyte, separating it from the surrounding granulosa cells.
This layer remains with the oocyte after ovulation and contains enzymes that catalyze with sperm to allow penetration.
So, the correct answer is 'Zona pellucida'.
Fertilization in humans is practically feasible only if 
The word ampulla is derived from the Latin word 'flask'. Being the second portion of the fallopian tube, it is the intermediate dilated portion which immediately curves over the ovary. This is the common site of human fertilization as both the ovum and sperms are simultaneously transported here.
Select the incorrect statement : 
In follicular phase of menstrual cycle. LH and FSH increase gradually and stimulate follicular development as well as secretion of estrogens by the growing follicles.
During pregnancy, which of the following is secreted through the urine of the mother? 
It is made almost exclusively in the placenta. HCG hormone levels found in the mother's blood and urine rise a lot during the first trimester. They may play a part in the nausea and vomiting often linked to pregnancy.
The fluid which is rich in calcium fibrinolysin and acid phosphates and contributes about 30% of the total volume of semen, is released by 
Atretic follicles are found in the 
Degeneration and reabsorption of an ovarian follicles before it fully matures and ruptures are called atretic follicles.
Both corpus luteum and macula lutea are
Both corpus luteum and macula lutea are characterised by yellow colour pigment, called lulein. It occur as a yellow area of retina as yellow spot.
